Your entire logical reasoning playlist helped me gain confidence, at least now i know i can solve these thanks is a very small word for all u have done!!
Really awesome explaination sir.👌.I've listened in very keen way such that I felt Your class ended so quickly.😅.It felt like a classroom☺️..Tq so much sir👍..keep rocking!!!!
Thank you so much Sir! I went through the entire playlist in 3 days and I am pretty much comfortable with such questions if asked in interview placement rounds.
If you find it's very confusing, then I will suggest you go on -learn with Anirudh sir RUclips channel, he explains all this with basics as well tricks
This analogy did make the understanding a bit easier. Think of the correct clock and the broken clock (clock gaining/ lossing time) as 2 cars in a race. If CAR-1 gains/wins at the finish line means that at one point both the cars were next to each other i.e (The correct time shown by both clocks) and eventually CAR-1 (broken clock) gained/lossed to CAR-2 (correct clock)
We can do mind calculation with that trick!! If 5min/1hr. 24hrs===> 24×5min= 120min=2hr/day. So for it to be 12 hrs it should be 6days from now on that is sunday 11am
for Q16: in 34 hrs clock gains 28.33 min, it means alarm should go off 28.33 mins before the correct time. but in 28.33 mins, a clock will gains 23.6 ~ 24 sec, so it should wait for 23.6 ~ 24 sec more. Because Q is asking when the alarm will ring, so it should ring after 33hrs32min04Sec i.e. at 10am 32min 04Sec Another Way is in 24 hrs clock gains 20 min, so in 33 hrs clock will gain 27.5 min i.e. 27 min 30 sec & will show 10:27:30 time although actual time is 10:00 only. For remaining 32 min 30 sec, the clock will gain 26.6 sec, means as actual time travels 32.5 min alarm will go off 26.6 sec early. So as it is 10:32:30, time in alarm is 11:00:26, means alarm should rings actually at 10:32:04 i.e. 26 sec early of 10:32:30. (Neglecting milliseconds-as it will make the calculation more lengthy & confusing)
One thing that separates from other is everything in one video,i missed my college lecture and similar like that i have got it here,one topic covered in one day/lecture
The 13th and 16th questions are wrong. The 13th answer will be 45 minutes and 9/11 seconds and the 16th answer will be 10 hours, 32 minutes, and 4/73 seconds. Because in the 13th question you forgot to calculate the thing that while the minute hand moves to 42 minutes hour hand moves by 21 degrees towards 11 so there will not be the difference of 8 minutes between the hour hand and the minute hand it will be more than that. The exact answer is 45 and 9 /11. 30(10) + 0.5t - 6(8) = 6t t = 45 and 9/11 And in the 16th question your answer was 28 minutes and 20 seconds but what is it? It is the amount of time jaggu's clock will ahead when 11 in actual real-time occurs, and you have subtracted 28 : 20 from 11 : 00. Means 11 : 00 in real-time and 11 : 28 : 20 in jaggu's clock. Here mistake is alarm will not set off on 11 : 00 in real time, It will set off when jaggu's clock is on 11 : 00 and real-time is behind that time and we have to find what would be the actual time in the real world. what we have to find is == real-time when jaggu's clock reaches to 11 : 00 what you have calculated is == time of jaggu's clock when real-time reaches to 11 : 00 and you have subtracted additional time The actual answer is 27 minutes and 69/43 seconds, and after subtracting answer will be 10 : 32 : (4/73)
This is the only topic of yours which has confused me a lot found it very complicated otherwise other topics that are taught by you are just like piece of cake
take the modulus of this that is the right formula bcz in cases like where angle is given and u have to find m or h there would be 2 possibilities with modulus
we can also use the formula angle=mod of 30H -(11/2)M to calculate the angle as well as the time at which the hands of a clock make an angle. here, H is for hour hand and M is for minute hand.
@@shivamtah2182 Mod is distance from 0. It is always positive as distance is positive. Here Mod will imply that the angle is positive measure of distance between the two hands.
@@ananthustalin2736 Question asking of angle trace for hour hand not angle between min and hour hand so at 12 noon angle is 0 degree and at 7 o'clock angle is 210 degree but min hand also moves 10 min so angle change for hour hand I.e. angle increase for hour hand by 5 degree so 210+5 =215 degree
[11/2M - 30H] is the simple formula for finding the angle between the two hands.....where M is minutes and H is hours 2Q). 10:25 = [(11/2×25)-(30×10)] =[137.5 - 300] = 162.5° { The ans will not be in negative}
Q.11 ) Straight line betw 2 and 3 o' clock is then when clock shows 3:45 and not 3:40 so the ans will be x = 60*45/55 = 540/11 = 49 1/11 min When I drew it on paper the ans came but just by drawing it might mis lead us so I did it on my watch and ans changed. But anyways your channel is super and I'm preparing for my cet for this coming june only with this and one more channel. Lots of appropriation towards you sir thank you and HAPPY GURU PURNIMA.
sir please make a video on counting figures, dice and cubes , mirror images ,paper cutting and folding . your videos are the best . never thought it would be so easy for me to solve sums . thank you sir .
Sir I have a doubt regarding 7th question Sir answer is 4.5 min But in question they said that the clock has gained time so from that we can say that time is running fast So as it is running fast 4.5 min has to be subtracted from 6:30 PM(Because it is running fast we have to set it right) So the answer from 6:30 it becomes 6:26:30 is it is right sir?
(ATQ) Clock time gains 20s for every three hour And what will be the time on friday .... Ques says gain not behind thats why we added 4.5 in 6:30 dear..if it says behind then we have to substract it...and no need to set it right and there is no need to set it just see it what will be the time on that day if clock is fast...
In question 2) Answer might be 197.5° or 162.5 Because 60 min-hr passes 30° 25 min-hr passes 12.5° Total angle between 10 to 5 is 210 So angle accurate angle is 210-12.5=197.5 If ask for small angle is 360-197.5=162.5
@@alisechan9067 its not 137.5 beacause from 10 to 5 there is 7 hours gap means 7*30 = 210degree angle and also every 12 min hour hand moves by 6degree then here its 25 minute so 12 degree aprox then 210 -12 =198 is the exact ans
use formultas: coincide (60 x H /11) , angle between hr and min hand - mod of | (30)Hour - (11/2)minutes | , time when angle is 90 between hands = (5 x hour +- 15 ) (12/11) ... + and - are giving respective two values.
This had helped me sooooo much👏👏😘..tquu tquu tquu tquu soo much sir for this video ...Really ur explanation made me understand very easy ..nd happy 🤗👍👍
Most simplest equation i can give u is,if y is hours and x is minutes,then (-30*y)+((11*x)/2) ignore the negative sign for the result. eg: @ y=2,x=40 if we input we get 160. tested on most times. here is a python program of the sort, y=int(input("Enter Hours")) x=int(input("Enter Mins")) Equation1=((1-(x/60))*30)+((((x/5)-y)-1)*30) print(Equation1) Equation2=(-30*y)+((11*x)/2) print(Equation2) Equation1 and Equation 2 are the same,But equation 2 is simplified...hope it helps
There is an error in the in the 13th problem 1:03:18. To find the time after setting the hands 8 mins apart, you should've find the coincidence and then add 8 to get 62.54 which is the time after setting 8 mins ahead the hour hand and you should have subtracted 8 mins from the coincidence to get 46.54 which is the time after setting 8 mins behind the hour hand. One of your solutions is 3 mins behind the original solution. Thank you...
In 16 no question.. I think there is having some mistakes..because u have calculated the total time gained for 34 hour i.e. upto 11 AM..but the clock actually moved till 31min 20 sec past 10 AM..these things i didn't got
@@saiprakash7223 yh for 34 hrs they have calculated... And 28 minutes 20secs gained by the clk... Then 11 am is as per the clk(he set alarm) but before 11 am the alarm rangs (because that is gains time as given in question))..... Did you get it sir??
Answer to question no.1 should be 147.5 degree... Because if minute hand and hour hand are 25 minutes apart then second hand would cover (30×5=150 degree). So in 25 seconds minute hand would cover (6÷60)×25=2.5 degree. Therefore, angle is formed between minute hand and hour hand is equal to (150-2.5)=147.50 degree. Kindly tell me whether it's correct or not.
In 1 min, the min hand covers 1 min space which is equals to 6°. In 1 sec, the sec hand covers 1 min space which is also equals to 6°. There are 25 min spaces, and 1 min space is equals to 1 sec which is equals to 6°, so it should be 25×6° =150°.
they have just asked the degree between min and sec hand diff clock .... initially even i did the same way but later thought be question just asked us to find only angle of 25 mins however we will have options in exam so choose the best
Sir your teaching is appreciated take a bow for that ❤️but sir the question of 7'O clock &8'O clock you taught,the calculation part is wrong i think,sorry if I would be wrong
Very good sir. 13th & 9th ques. Are new kuch naya sikhne ko mila, likes and views are less but concept is new, plz all of u don't watch after seeing likes and views. Simply watch randomly . Good nice one and method is also nice of cross multiplication
Thanks, Shubham. We have got some interesting videos on QA, Resume Writing, HR Interview and Interview Q & A on core subjects as well. Do take a look :)
Sir for problem number 2 why did you consider the travel distance in degree of hour hand (30*10) , because the question is simply asking angle between the hr and min hand and not about the angle covered by hands of clock in the past?
How many times are the hour hand and the minute hand of a clock at right angles during their motion from 1.00 p.m. to 10.00 p.m.? (I.A.S., 2009) (a) 9 (b) 10 (c) 18 (d) 20 In this question the answer should have been 16, since from 3 to 4pm and 9 to 10pm, the hands will be at right angle only once whereas for the rest of the 7 hours the hands will be at right angle 2 times every hour. Which makes it 7*2 = 14 + 2 = 16 The correct answer given in the book RS Agarwal is c] 18.
Sir in 16th question u should take 59 min and 60 sec ...viz 28 min 20 sec should be subtracted from 59 min 60 sec to get the right answer. Kindly check and revert back.
The only channel I found where I can understand each and every single concept.. tqsm sir 💕 Sir please provide a seperate video for the calendar questions as soon as possible 🥺
wonderful sir, really you have made quality videos and it is helpful for learn to concept and also your trick is really helpful for us.please sir make some videos for English for job interview and placement test
sir, I have some doubts about the 3rd question I think the answer will be 5. because in question has not given find the angle between the hand of the clock but in question has provided find how much turn hour hand.
In question no 13 right answer would only be first one cause the question asks for a time between 10 to 11 o clock, or is it related to am and pm , please elaborate.
I'll provide a very easy trick... Whenever you have to find angle between minute hand and hour hand of a clock. Just assume a hypothetical clock in which in 1 min the total degree equls to 5.5 and not 6. By this no need to minus the 0.5 degree of hour hand, and the answer will be direct. For eg, Find angle between 3:20 pm, Ans : 1min = 5.5 ( hypothetical clock ) 20min = ? , it will be 110° , now at 3 pm the angle would be 90° , therefore 110° - 90° = 20° Final answer would be 20°. Just practice few sums you'll get clear.
Sir in last sum time is 11 am then why are we taking 1 am for making it 24 hours and then again adding 10 h ours time ?? why can't we take 11 am directly?
You wrong 150+12.5 if small angle and 210-12.5 if large angle because after 25 minutes hour hand will move up words so there is no sense of minusing....12.5 from 150

I have a formula to remove any angle of time .
30xHour - 11/2xminutes
Ex 1.
Angle between 10:25=
30x10 - 11/2x25
=300-137.5
=162.5°
Bukchik bukchik
thank youu!
but the correct ans is 360 - 162.5 =197.5 degree
@@abish.v.s6262 both are correct
Exactly i found the same answer and I'm confused after watching this video
We can do mind calculation with that trick!!
If 5min/1hr.
24hrs===> 24×5min= 120min=2hr/day.
So for it to be 12 hrs it should be 6days from now on that is sunday 11am
i don't understand this example 😣
I did this exact mind calculation
for Q16: in 34 hrs clock gains 28.33 min, it means alarm should go off 28.33 mins before the correct time. but in 28.33 mins, a clock will gains 23.6 ~ 24 sec, so it should wait for 23.6 ~ 24 sec more. Because Q is asking when the alarm will ring, so it should ring after 33hrs32min04Sec i.e. at 10am 32min 04Sec
Another Way is in 24 hrs clock gains 20 min, so in 33 hrs clock will gain 27.5 min i.e. 27 min 30 sec & will show 10:27:30 time although actual time is 10:00 only. For remaining 32 min 30 sec, the clock will gain 26.6 sec, means as actual time travels 32.5 min alarm will go off 26.6 sec early. So as it is 10:32:30, time in alarm is 11:00:26, means alarm should rings actually at 10:32:04 i.e. 26 sec early of 10:32:30. (Neglecting milliseconds-as it will make the calculation more lengthy & confusing)
Being M_Indian Exactly. Was searching for a comment which says solution to 16Q is wrong. You were spot on!! Cheers!!

Thank you
It is 10000 times better than clases. U saved us 🥰
One thing that separates from other is everything in one video,i missed my college lecture and similar like that i have got it here,one topic covered in one day/lecture
Nice joke
Question 2 asked to calculate the angle b/w the angle between the right and left hand of the clock. Answer should be 197.5 I think.
Yes 198 u think
right yar.....when we just observe clock...we can see angle is already above 180 degree, when time is 10:25.......sir can u please solve this query
angle must b 197.5 according to me
Yes 😂😂 how can it be 312.5
Thats the comment i was looking for i also got 197.5 i think Sir didn't do 360-162.5=197.5
The 13th and 16th questions are wrong. The 13th answer will be 45 minutes and 9/11 seconds and the 16th answer will be 10 hours, 32 minutes, and 4/73 seconds.
Because in the 13th question you forgot to calculate the thing that while the minute hand moves to 42 minutes hour hand moves by 21 degrees towards 11 so there will not be the difference of 8 minutes between the hour hand and the minute hand it will be more than that.
The exact answer is 45 and 9 /11.
30(10) + 0.5t - 6(8) = 6t
t = 45 and 9/11
And in the 16th question your answer was 28 minutes and 20 seconds but what is it?
It is the amount of time jaggu's clock will ahead when 11 in actual real-time occurs, and you have subtracted 28 : 20 from 11 : 00. Means 11 : 00 in real-time and 11 : 28 : 20 in jaggu's clock. Here mistake is alarm will not set off on 11 : 00 in real time, It will set off when jaggu's clock is on 11 : 00 and real-time is behind that time and we have to find what would be the actual time in the real world.
what we have to find is == real-time when jaggu's clock reaches to 11 : 00
what you have calculated is == time of jaggu's clock when real-time reaches to 11 : 00 and you have subtracted additional time
The actual answer is 27 minutes and 69/43 seconds, and after subtracting answer will be 10 : 32 : (4/73)

Thanks, Divya. Taking the feedback.
Stay connected :)
Finally found in english teaching with clear class thank you
You are welcome! :)
You can also use this formula in some sums:
Angle = 30*Hour-5.5*Minute
Then you have to go and teach 😂
This is same formula as it is told in this video bro
take the modulus of this that is the right formula bcz in cases like where angle is given and u have to find m or h there would be 2 possibilities with modulus
Q. No.2 angle b/w two hands of a clock is = mod 11/2m -30h
and if the angle is, 90 degree = mod 30h-11/2m
we can also use the formula angle=mod of 30H -(11/2)M to calculate the angle as well as the time at which the hands of a clock make an angle. here, H is for hour hand and M is for minute hand.
What is mod
thanks!
@@shivamtah2182 Mod is distance from 0. It is always positive as distance is positive. Here Mod will imply that the angle is positive measure of distance between the two hands.

Sir I have a doubt regarding 7th question
Sir answer is 4.5 min
But in question they said that the clock has gained time so from that we can say that time is running fast
So as it is running fast 4.5 min has to be subtracted from 6:30 PM(Because it is running fast we have to set it right)
So the answer from 6:30 it becomes 6:26:30 is it is right sir?

All the best!
In question 2) Answer might be 197.5° or 162.5
Because 60 min-hr passes 30°
25 min-hr passes 12.5°
Total angle between 10 to 5 is 210
So angle accurate angle is 210-12.5=197.5
If ask for small angle is 360-197.5=162.5
the answer is 137.5 coz 150 degree- 12.5 degree

Now I'm perfect at clocks concept Sir, I'm very confident that I can solve any question in clocks concept.... Thank you so much Sir.....🙏🙏🙏
I like how you say 'okay very bad drawing' every time you draw a clock.
Haha pehele Padhai kr le
It's really easy to catch up the important points from your lectures and easy to understand, thank you for this wonderful session sir
This had helped me sooooo much👏👏😘..tquu tquu tquu tquu soo much sir for this video ...Really ur explanation made me understand very easy ..nd happy 🤗👍👍
Upto now every concept is clear to me in reasoning from this channel.... But this topic somewhat difficult for me
Most simplest equation i can give u is,if y is hours and x is minutes,then
(-30*y)+((11*x)/2)
ignore the negative sign for the result.
eg: @ y=2,x=40
if we input we get 160.
tested on most times.
here is a python program of the sort,
y=int(input("Enter Hours"))
x=int(input("Enter Mins"))
Equation1=((1-(x/60))*30)+((((x/5)-y)-1)*30)
print(Equation1)
Equation2=(-30*y)+((11*x)/2)
print(Equation2)
Equation1 and Equation 2 are the same,But equation 2 is simplified...hope it helps
There is an error in the in the 13th problem 1:03:18. To find the time after setting the hands 8 mins apart, you should've find the coincidence and then add 8 to get 62.54 which is the time after setting 8 mins ahead the hour hand and you should have subtracted 8 mins from the coincidence to get 46.54 which is the time after setting 8 mins behind the hour hand. One of your solutions is 3 mins behind the original solution. Thank you...
You can easily calculated by using formula 10.25 angle between is
30*hours-11* minutes/2
1:01:50 45(9/11) is the ans.
14th question last calculation,im pretty sure i have calculated it 20 time now....how is 38*24*60/11*62==6080/77

You are God for job seekers.. Great explanation sir
In 16 no question.. I think there is having some mistakes..because u have calculated the total time gained for 34 hour i.e. upto 11 AM..but the clock actually moved till 31min 20 sec past 10 AM..these things i didn't got
Yh that is what the clk has wrong time!!
Me too....plz any one clarify...😐
@@saiprakash7223 what is you doubt sir?
@@suffrinbegam.s8157
Yah madam...The same question that sarup das asked
@@saiprakash7223 yh for 34 hrs they have calculated... And 28 minutes 20secs gained by the clk... Then 11 am is as per the clk(he set alarm) but before 11 am the alarm rangs (because that is gains time as given in question))..... Did you get it sir??
Answer to question no.1 should be 147.5 degree...
Because if minute hand and hour hand are 25 minutes apart then second hand would cover (30×5=150 degree).
So in 25 seconds minute hand would cover (6÷60)×25=2.5 degree.
Therefore, angle is formed between minute hand and hour hand is equal to (150-2.5)=147.50 degree.
Kindly tell me whether it's correct or not.
In 1 min, the min hand covers 1 min space which is equals to 6°.
In 1 sec, the sec hand covers 1 min space which is also equals to 6°.
There are 25 min spaces, and 1 min space is equals to 1 sec which is equals to 6°, so it should be 25×6° =150°.
they have just asked the degree between min and sec hand diff clock .... initially even i did the same way but later thought be question just asked us to find only angle of 25 mins however we will have options in exam so choose the best
Sir, thank you so much for your effort.. It's really really helpful..
Sir your teaching is appreciated take a bow for that ❤️but sir the question of 7'O clock &8'O clock you taught,the calculation part is wrong i think,sorry if I would be wrong
Your teaching is awesome. U keep it simple and interesting.
Very good sir. 13th & 9th ques. Are new kuch naya sikhne ko mila, likes and views are less but concept is new, plz all of u don't watch after seeing likes and views. Simply watch randomly . Good nice one and method is also nice of cross multiplication
Thanks, Shubham. We have got some interesting videos on QA, Resume Writing, HR Interview and Interview Q & A on core subjects as well. Do take a look :)
Make one more video on "Calendar"
Where is calendar video?

Sir in Question no 5, if we divide 11:60 by 11:25 then answer will be 00:45 not 00:35
Starting point very nice editing anna. I like that bgm😍👍👍👍
Sir for problem number 2 why did you consider the travel distance in degree of hour hand (30*10) , because the question is simply asking angle between the hr and min hand and not about the angle covered by hands of clock in the past?
In question no 14.
In 24 hours both the hands meet for 22 times ..for every meet it gains 38/11 mins.. therefore in total its 22*(38/11)=76 mins.
This is not perfect clock so 22 times a day is maynot be possible
in 10th question when the minute hand moves, the hour hand will also moves forward but you didnt considered that..why?
Same doubt here🤔
How many times are the hour hand and the minute
hand of a clock at right angles during their motion from 1.00 p.m. to 10.00 p.m.? (I.A.S., 2009)
(a) 9 (b) 10
(c) 18 (d) 20
In this question the answer should have been 16, since from 3 to 4pm and 9 to 10pm, the hands will be at right angle only once whereas for the rest of the 7 hours the hands will be at right angle 2 times every hour. Which makes it 7*2 = 14 + 2 = 16
The correct answer given in the book RS Agarwal is c] 18.
Thanks for you effort it is very helpful to me you made problem on clocks so easy and effortless

In Question number 9, how 170hours is multiplied with 120 seconds and divide it by 408 seconds ? no need of converting the 170 hours into seconds?
Awesome explanation sir make a video on calendars too...👀
Thank you so much sir
Bestest video on RUclips 🙌🏼
i understand everything but this cross multification. there is something sus
there is mistake in 13th question , one of the answers should be 45 -9/11
Sir in 16th question u should take 59 min and 60 sec ...viz 28 min 20 sec should be subtracted from 59 min 60 sec to get the right answer. Kindly check and revert back.
I have done wonderful ride with your class bro..... heartful thanks
what did u ride 🍆
The only channel I found where I can understand each and every single concept.. tqsm sir 💕
Sir please provide a seperate video for the calendar questions as soon as possible 🥺
Soon. Stay connected.

Your all videos are very much helpful to us thanku sir and plz make a video on foor also plz🙏
Sir in the 3rd question the hour hand has moved through 215 degree from noobnot 25
Hi the explanation is v good
Can u give provide some similar tutorial on calendar and dates and days
Explained beautifully....got all the concept in one go...
wonderful sir, really you have made quality videos and it is helpful for learn to concept and also your trick is really helpful for us.please sir make some videos for English for job interview and placement test
superb said seriously u have cleared my all doubts thank so much sir
Really you are teaching away some sir👍
i Face difficulty after question number 9
Sir please upload a video on CALENDERS
Sir in Q 14,answer will be 27360/11 min or 80 80/341 minutes
sir, I have some doubts about the 3rd question I think the answer will be 5. because in question has not given find the angle between the hand of the clock but in question has provided find how much turn hour hand.
Thank u for making such concepts easy !!! :)
Sir i just love ur classes🤩💯💯👍👍🔥
In question no 13 right answer would only be first one cause the question asks for a time between 10 to 11 o clock, or is it related to am and pm , please elaborate.
Very nice explanation and good easy lyrics to solve
I'll provide a very easy trick... Whenever you have to find angle between minute hand and hour hand of a clock.
Just assume a hypothetical clock in which in 1 min the total degree equls to 5.5 and not 6.
By this no need to minus the 0.5 degree of hour hand, and the answer will be direct.
For eg, Find angle between 3:20 pm,
Ans : 1min = 5.5 ( hypothetical clock )
20min = ? ,
it will be 110° , now at 3 pm the angle would be 90° , therefore 110° - 90° = 20°
Final answer would be 20°.
Just practice few sums you'll get clear.
Nice!!!
Thank you so much sir..for this awesome explanation..it is really very helpful for us!!
Sir 3rd question was solved incorrect. Correct ans is 155 degree
Sir in last sum time is 11 am then why are we taking 1 am for making it 24 hours and then again adding 10 h ours time ?? why can't we take 11 am directly?
You are doing great job sir
Thank you for making its most simpler
If a minute hand is moved by 25 mins then relative to it hour hand will move 0.5 degree per minute so anwer will be 150-12.5= 137.5 degrees
You wrong 150+12.5 if small angle and 210-12.5 if large angle because after 25 minutes hour hand will move up words so there is no sense of minusing....12.5 from 150
