Angle = 30H - (11/2)M
Perfect
👌👌👌👌👌👌👌👌👌👌👌👌
And why should I remember this, if I can do this conceptually in same time.
Easy
@@NoOne-ky1er Substitution in formula is easier than doing everything like this. I need to crack NTSE and there is 100 questions for 2 hours so it's impossible without shortcut.
Clock wise direction =| 11/2m-30H |
Anticlockwise= | 30H-11/2m |
For angle bw hour and minute hand😀
how to apply this??
Absolutely right
After that I am getting answer as 5:43⁷/¹¹....can you help me out please?
Another way (6:30 pm)
Hour hand at 6
Minute hand at 30
To move to 30,minute hand needs to go 180°
In 1 minute the hour hand goes .5°
So just do 30*.5=15°
Therefore when the minute hand comes to 30,the hour hand goes away from minute hand in 15°
So angle between hour and minute hand at 6;30 is 15°
It is simple when you use in mind calculation.
Bhai apka knowledge toh kamal ka he
😂
I always use this method instead of formulae in video😊
Angle = 30(hour)-5.5(minutes)
= 30(6)-5.5(30)
=180-165
=15°
Bro is this a trick...?
@@sanferico5578 yea
It's more simple
so easy 😍
Wow.. Thanks for sharing ❤
Formula method: 30(H)-11/2(M).... Now let's apply it. H stands for hour that is 6 and M stands for minutes that is 30... 30(6)-11/2(30) this gives u... 180-165=15...........
It fails if they asked to find right angle between 5:30pm and 6:00pm
@@kingmaker9082 I HAD SIMPLE FORMULA FOR THAT TAKE
55=60
2ND STEP(U ASKED 5 AND 6 CLOCK SO 5-3 = 2, 2*5=10) AND (5+3=8, 8*5=40)
THEN SOLVE IN 2 WAYS
1ST
55=60
10=X(CROSS AND FIND THE SOLUTION)
2ND
55=60
40=X(CROSS AND FIND THE SOLUTION)
For tnpsc if we use this methods means "timeout go away." see if angle bn 6.30 means sum all 30 degree from 12 to 6 30+30+30+30+30+30=180+(30mins/2)=195-180=15

You should simplify the numbers in your calculations to make it easy. Like 13/2 instead of 39/ 6 in the first question
In first question as the time is in 1:5 ratio we can use the formula Minutes/2
It gives u 15
U can do this to every time which is in 1:5 ratio
And if the time given is in 1:4 ratio then Minutes should be multiplied by 2 that will give u the angle.
I like your teaching really u made me ro become NTSCE TOPPER MAM REALLY
Formula for Angle btw clock hand is -
Angle = 60×H - 11×M is divide by 2
For eg : time 4 :20 then the angle is -
60×4 - 11× 20 is divide by 2 = 10 * degree
This is the short cut method 👍
S
bhaiiii laundaaa h tu bhagwan tera bhala krrreee
edit yours self its angle =30h-11xMdivided by 2
Why does that formulae not work in rest of the problems ??
How so cute u r like ur teaching style. . Dont take in wrong way.
Simp
So how should we take it ?
Huh?
As a joke.......🫣
Let there be safe environment for women
Akka pls do more problems on angles. As one problem is difficult to understand. Pls do 2 problems.
Nicely, explained this concept thank you 😊
Hi pragati
😎😎
@@jatrahul194 chup reh
Im Rohith from VIT vellore ...big fan of your teaching mam... was very useful watching your videos...i cleared my exams
last question ✍️No need of this much lengthy explaintion!!!
Firstly solve angle between hour hand and minute hand using formula
angle = 30H-(11/2m)
If angle < 180 then
subtract (360 - obtained angle )
Which will be reflex angle.
The question before the last can't we solve it using formula ???
What if angle >180 ??
@@mettuudaykiran2917 Just write it down, it's the answer.
Use the same formula for entire problem (except one) of this video
That is ,
Angle = 30H-(11/2)M
And why should I remember this, if I can do this conceptually in same time.
@@NoOne-ky1er u could save some time ?

yess broo...
Your teaching is superb.thank u.
Madam make it a simple. Minute hand moves 6° every minute and hour hand moves 0.5° every minute so ultimate angle after one minute is 5.5°and calculate accordingly.
How bro can you explain this
@@SriRam-ce3hi suppose the question is- find the angle between minute and hour hand when its 4.30.
While calculating every consider the perfect timing like in this case-4.00. Now minute hand will travel 30 minutes which means it will travel 180 degree ( minute hand moves 6 degree for a minute, so 30*6=180). Now for every minute hour hand moves 0.5 degree. So after 30 minutes hour hand will move 30*0.5=15. Now we know angle between each digit of watch. In this case angle between 4&6 is 60 degree. So 60 minus 15=45 degree. This is the answer. This may look lengthy but try such examples with pen paper
@@SriRam-ce3hi or other method- after every minute both hands move 5.5 degree. So after 4.00 minute hand will move 30 minutes. So 30*5.5=165 degree (this means hour hand moved 180-165=15 degree). Again the angle between digit 4&6 is 60 degree. So 60-15=45 degree is the answer
Thanks a lot bro
Tell me mail id bro
In 24 hours,
Minutes and Hours hand coincides 22 times
Minutes and Seconds hand coincides 1438 times
Minutes and hours hand coincides every 65 minutes not 60 mins
Ur teaching is beautiful like you mam 😘
cute face beautiful voice & awesome teaching.
Beat method: 6:30 means hour hand is between 6 and 7 so angle will be half of 30 so 15 degree
Mam use shortcuts instead of lengthy process that helps to save time in cracking exams
Madam we can use the formula for all sum (A=30h-5.5m) ,why you didn't use that madam while I use that and get the answer with 4,5 simple steps madam ,but anyway thankyou so much madam
Mam Plzz can u make other video for clock ,I can't get that what u teached
Best video. I am very confident in this now. Thankyou
Angel=30(H)~11/2(M)
Shortcut of finding between angle
Thank you
Tq ,excellent
Tqq super 👏
Madam your teaching way mind-blowing
In the first problem .. I. e 30 ÷ 2 = 15°
If hour and min hand lie on the same axis ..
Q. Solution:- 15° angles between the hour hand and the minute hand when the time is 6:30 clock.
ma'am yours calender is good but your clock have some issues .Kindly solve that .............
your 'faithfully
hari om bhatt
(60H-11M)/2 ANGLE can be found with this formula happy to share........
Q)for 7.23hr angle ?
A) (60*7-11*23)/2=83.5degree
Teaching is super mam,
Please give the tricks about reasoning problems also mam
Benoliya what is Angela s
Tq madam, good class
thanks maam, its a perfect video as per my search query
Thank you for best explanation
In all videos on u tube one type of problem is MISSING.
Q1)A wall clock takes 10 seconds to strike 6. how much time it will take to strike 12 ?
Q2) a wall clock strike 12 and it takes 33 seconds to do so. how much time it will take to strike 4
Q1.22seconds
Q2.9 seconds
Thank you so much ma'am this video was very helpful.
very well explained and all videos are thought me very easiest method,but the thing is in most of all videos u always stand covering the board completely while solving problem, so we are not able see the board properly, so try to stand beside board while solving.
Sure and thanks for following our videos
Just like the way u r teaching , 💯👏 keep posting videos
Mm
mam your really so beautifull and pretty and your concept explanation is quite good
6 : 30
Just divide min by 2 i.e 30/2= 15
Then 6 and 30 are overlaping so 0 Degree.
0+15=15 degree
Consider h as hour and m as minutes the angle for 6:30 can be calculated using the formula
30h+0.5m-6min. Just a shortcut.👍
Is this formula applicable to all problems
@@sccutsz for problems based on finding angles yes it is
You have to apply Modulus so as if it gets negative answer , it becomes positive
Really good videos within short time , thanks mam
Most welcome 😊
I love your style of teaching ❤
I can never seen a talented teacher like you
True
u r looking beautiful and ur teaching too
It's very useful...
Mam for the first problem minute/2 gives the answer in fraction of seconds...
Can we do that for all similar questions?
30H-11/2M
This method is quite easier,....
To much long. We can find in a short way. But i appreciate your hard work.
Gud explanation Ishwariya .
Even logically without any formula u can do in just 2 steps.
Have doubt.
When the min hand gains 15 mins, by that time hour hand would be somewhat forward. Then how could say that they are coincide?
Similarly to the right angle question?
Can you make a video on calanders keeping the aptitude level to the level of iim mba .
This method is quite lengthy
We can go to gjp clock problems
Can you show the short method?
These videos are too good... don't know why there's hardly any views... .
Very nice mam
This was very helpful...thank you👍
one can also solve type 2 problem by using relative speed concept.
Yes bro that is more efficient
Madam in part 2 your hair became short why madam🤔
నేను చాలా మంది టీచర్లు క్లాస్ చెప్పేవాణ్ని చూసాను కానీ మీ లా అంత ఓపిక నీలా అంత అందంగా చెప్పిన వాళ్ళు ఎవరు చూడలేదు ప్రస్తుతం ఏం జాబ్ చేస్తున్నారు మేడం
Superb 🎉🎉
While solving sum on the board..you cover all the area..i am not able to see the simplification process 😅
Thank You!
Very good 👍
Nice
Tq ma'am I'm going to pass my exam
Mam your language is so beautiful or wonderful
12:06 why it was 600 it should be 60 right
please answer this4 me.a clock gains 4 mins after every six hrs.if it was set to read 9 am on monday what was the actual time on wednesday of the same week if the clock indicated 9 pm? thanks
Nice Explanation Mam🤗😌
2 ; 15 afternoon to 2 ; 35 afternoon upto different minutes how many degrees madam ?
I will give you formula
30*hour -11/2*min
Good work but kindly don't hide half of the board while talking as we can see only your back and not the solution.
we can just use first method,like hour hand angle taking 3hours and say x min find its angle
2)find minute hand angle taking x minutes and both should meet means same angle covered by both hands.this is for better understanding
5:35 waqt badal diye jazbat badal diye
Thankyou mam u are best
Madam 1 kind request...pls dont hide the board while writing...
Thanks for the video mam!!!
U are so beautiful mam😁🥰👍
Mam looks beautiful btw 😍
in question 2, it says at what time? so after 16 4/11 min, what time will it be?
Thank you so much
Your teaching super medam
I saw u after long time
Nice madam explanation is as good as you look.
Mam aapki smile bahut aachi hai
very nicely explained
And you are from south India. 🇮🇳
Excellent class
Please upload the videos for time and work , combinations
Mam can you make a video on paper folding and cutting please
You teach very well but please let us see the board clearly you always stands in front of it
Per hr 30 degree..then at 6.30 it's haf tha 30 degree .. obviously 30/2= 15 simple
It helped a lot thank you mam
