10:26 An amount becomes 7 times in 15 years. In how many years will the same amount become 10 times? The rate of interest remains the same for both cases.
13:16 A sum becomes Rs. 3000 at the rate of 12% per annum (simple interest). The same sum becomes Rs. 3300 at the rate of 15% per annum (simple interest) in the same duration. Find the sum and the duration.
17:41 A man got Rs. 130 less, as simple interest, when he invested Rs. 2000 for 4 years as compared to investing Rs. 2250 for same duration. What is the rate of interest?
20:22 1/5 part of an amount was given at 3% simple interest, 1/3 part was given at 5% simple interest, 2/5 parts at 9% simple interest and remaining part at 11% simple interest. The total interest received was Rs. 297. How much amount was originally given?
24:21 Rs. 20400 was divided in two parts and then invested. One part invested at 6.25% for 8 years yields the same interest as the other part invested at 7% for 5 years. What is the value of smaller part?
26:52 If simple interest on a certain sum for 15 months at 7(1/2) % per annum exceeds the simple interest on the same sum for 8 months at 12(1/2)% per annum by Rs. 32.50, then the sum in Rs.
29:32 If simple interest for 2 years for a sum is Rs. 600 and compound interest for the same sum for 2 years and same rate of interest is Rs. 645, what will be the rate of interest? EASY
36:47 Aman invests Rs. 8000 at some rate of interest. Being simple interest the money doubles in 5 years. Raj sees this and invests Rs. 6250 for 3 years at same rate of interest. How much interest does Raj get?
38:19 Aman got a salary of Rs. 8600. The salary was invested by him in two parts. Find the difference between the two parts of his salary, if in first part he got some simple interest at 15% per annum in 4 years, which was same as the second part which he invested at 20% for 3 years?
39:54 Ram gets Rs. 2600 for Rs. 2000 in 5 years at some rate of simple interest. Had he invested in other places where rate of simple interest is 3% more than current rate, how much would have Ram got in same time?
45:06 Suresh for 2 years invested Rs. 500 in SBI. He also invested Rs. 300 in ICICI for 4 years. At the end he received Rs. 220 from both banks as simple interest. What must have been rate of interest?

God...Thats new 🤐
Can you please send the instalment problem link? .I couldn’t find it in this channel
Check question no .9. That equals to 16000 not 8000
8th amswer is not clear
Can u explain on topic geometry
Don't listen to others comment it's one of the best channel to learn aptitude
Don't be emotional, it is wrong explanation
@@KUMAR-jz2oc konsa wrong he
@@electroniks2273 bro initially whatever he told in this video all those are wrong explanations,
What wrong .
Please explain what is wrong is this video
Really appreciate your efforts . Guys don't look for short time video , because concept may give you 10% of problem solving technique but when you start solving problems you get more clearance in your concept and this is provided here.
Anyone in 2024?

kyu bhai ??
Or naet
I'm from 2025
Best channel to learn aptitude and reasoning. I have recommended this channel to all my friends , and my juniors
Thanks, Vishal! That's very kind of you. :)
@@CareerRideOfficial how you know his name because his yt channel name is collage world how ?
Nice lecture sir, my doubts are cleared now. U have taken little bit hard problems from the begining of this lecture. So may be it is difficult for those students who didn't sloved some basic problems on S.I. before this lecture.But it is perfect lecture for me . U explained in simple language and quick not too much longer time. We just need more practice to solve quick. And Best of luck to all guys
Thank you, Vijay. Do follow the link in the description box below for the practice questions :). All the best!
Easier way to do the second sum:
subtract 1 from both amounts (ex: 7 times means 1principal + 6interest, similarly for 10 times, 1principal + 9interest). We do this because your principal remains constant, your interest amount goes on increasing.
Using cross multiplication:
6 x 15
9 x ?
You’ll get the answer as 22.5
Good one thanks ..
lol Imran Sir's trick. :P
yeah mann, I did this ques with same trick 👍
its literally unitary method
Sir in first question,suppose if we do only using prt/100 also,we will get the same answer even though whether in question it is given quarterly or half yearly or monthly,then what is the difference using separate formulas for each?
Brother explanation is nice but firstly explain some easy problems then move on to medium then hard ur prbloms seems to be difficult from starting onwards it may tend to getting tension how difficult SI is so my humble request is explain easy problems so everyone can easily understand
Humble request, please start from easy problems instead of starting from difficult ones.
I couldn't understand the explanation of the difficult problems, hence had to leave the video in between.
Hope you keep all kinds of students in mind while explaining.
Wooooooow you solved my problems easily thanks sirji
in ques.1 if the rate given is quarterly rate, then there is no need to divide the rate by 4. we will only multiply the time with 4.
+1
Yes
yeah you'll get interest amount as 5200
Yess
@@sanjaychakrawarty7350
Yes correct!!!!
Easier method for question 3:
This will work only with simple interest so keep it in mind.
The increase in ROI is 3% and the amount increased is Rs 300, therefore you can equate 1% as Rs 100 as the principal remains constant.
So, 12% will be Rs 1200 interest. Subtract from Rs 3000 and you have your principal.
For Time,
1200=(1800x12xT)/100 =50/9
prathamesh brother can you give me your short tricks please
Yes bro could you tell
I have a question over there it is written as per annum can't we take it as per annum as time period?

Questions 2
7time - 15 years
10 time - ?
14 time - 30 years
Using reiteration technique we get 22.5 years. 5sec solution. Avoid compilation.
Note: only applicable when rate of interest is same.

Nice one brother👌👌👌
Your explanation is really good Thank u for the video
very helpful for me sir...thanks a lot🤗🤗🤗
Angreji me samaach hota hai. Dhaniawad hai Sire.... Lots of appreciate from North Eastern Regions.
The video is super amazing 😍
For the ques 8 i think simply CI-SI can give us the ans .
Amazing course. simple interest video should come before compound interest video in the playlist
If you are considering T As a year then how 2T can be considered as 6 months instead of 2 year
Thank you so much ❤i understood this topic and now it is easy to solve sums.
Glad to hear that
In question no. 9 if he earns 8000 in 5 years then rate will be (8000/5)=1600%...???
Didi u r so beautiful
Nd really osm video...concept is clear...
Your explanation for each and every problem was clear-cut, and your teaching style is truly commendable!👏😊I sincerely appreciate your dedication to providing such helpful guidance sir. Thank you🙏
It's not
It was an excellent lecture sir thanks a lot sir this topic is now easy for me❤️❤️
Very helpful, Sir..Thanks a lot..
respected sir,
in simple interest qno 9
why we couldn't minus the two ( ci-si) rather doing all those things
Thanku sir, very helpful...
Sir this is one of the best channel I ever landed for aptitude ,thank u for being with us through this platform

thankyou so much ....jen got placed🥰
You are teaching us in a very easiest manner Sir. Thank you very much for your kindness teaching 🙏🙏🙏🙏🙏🙏🙏☺️☺️☺️☺️☺️☺️☺️
Thank you..Well explained..
awesome.... thank you
You said that, the 2 in half yearly,4 in quarterly, 12 in monthly cancels out then Why u wrote the formulas for half yearly, quarterly,and for 1 month.....
Isn't the Simple interest formula enough to solve the problem
+1
But for the safe side u must know the changes ,else there is a chance of making a mistakes in compound interest , same method is used but formula is different .
@Shaily Priyadarshini I think this question answer is 5200
@Shaily Priyadarshini beacuse there are 10quarters in two and half years for each quarter 8% so for 10 quarters 80% of principal which is 5200
@@chandrasekharnaidu4394 yes right! i feel same but why is it not so?
awesome sir
Thankyou sir for this whole playlist
When we are doing for quarterly or half yearly questions, if we multiply time and divide rate by the same number, it always gets cancelled and it becomes same as calculating yearly, so may be I think we need to multiply the time, but do not divide the rate, bcoz it stays the same for each interval the intrest is calculated
"Very easy"----> but every question has a trick . No easy question in every video. But very very helpful to see such kind of tricky mathematics . 😦
Tq sir.good explained
every topic of this playlist is the most important topic 😁😁
really very helpful sir, thanx alot sir..
Thanks, Rishi! :)
Sir this is very helpfull
Sir please make a video over installment
In question no. 1 the rate of interest is 8% quarterly. Therefore in one year it will come to 32%. and the Simple Interest for 2.5 years will be=5200. Finally the total amount =6500+5200=11700. How is it possible to get simple interest only 1300 @ 8%quarterly.
In question they asked Quarterly what will yield... You calculate for one year. So from your answer SI=5200(one yr interest amnt) just divide it by 4(Quarter).. the answer will be SI=1300
@@selvaganapathy4848 for quaterly rate is 8% they given. then for 1 year it will be 32%
Same doubt. Quarterly interest is 8% so yearly it will be 32%. We always need rare of interest yearly. So as per this SI us turned out to be 11700 but I am confused
sir make video on geometry and trigonometry for RPF SI exam
Thank you so much sir for the help.
In last sum of SI, the money received as interest was 220 from both bank i.e 440 total interest. But you have consider only 220 Rs while solving the problem.
Yea even i was thinking about that
I also think so.... But if we consider Rs220 nd Rs 220 from both the banks.... Then we can also calculate SI seperately and if we do it....we got 2 different rate of interest (r)
22% and 18.33%.... but acc. To question we should have common ratio (so it's correct the money comes from both the banks combine)
Also they not mentioned the rate of two diff bank as it same or diff
Great explanation sir 😊
Great job
Thank you so much sir for this very helpful session.
One of the best channel for aptitude ❣❤
Just awesome Sir ❤🎉
Most awaited dialogue "See how easy it is."
Thankyou so much..God bless you and your channel🥺😌
It's taking long time... Is this method useful in compititive exams?
Can you please help us with some short cuts

Very nicely taught
You tell it's very easy in the beginning of every question, & I tried my self but I can't solve it, then I was in dipression
Thank you ♥️
in 3rd question by using which formula did you calculate value of T?
Its really helpful and it clears all doubt related to day to day calculations.
May I get the link of the video on the topic Installment
thankyou
Thanku so much sir!!! Your way of explaining examples is just awsm ...
Nice lecture my doubts are cleared now
thank you sir
your video on SI has taken away my fear of SI related problems. Thank you so much
Bro some of the concept are wrong, be carefull
Eg. Q1
Excellent
Thanks ..
your videos are really helpful for placement preparation.
Awesome Explanation
Outstanding explain the topic
awsm video ...
Thanks Sonam!
In the second question
Consider the change in interest.
Only and apply the rule of rati
6 ....times in 15 years
9 times in howmany years
9*15
------- gives 22.5 years
6
so happy with the teaching
😇
In Question 6 (25:00), it is not mention that the smaller part is invested at 6.25% for 8 years. then there must be 2 answers for this question, if we assume that smaller part is invested at 6.25 % for 8 Years or it is invested at 7% for 5 years.
Sir your videos are awesome👌 but can you clarify the 1st problem is right or wrong? I feel it is wrong approach
Yes
Rate multiply by 4 .. rate must be annually
Hai , will you please tell
How come you take time 1 year time period in 5th problem ?
They didn't give actually
Sir, Can u please upload installment related videos in simple and compound interest...?
