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?
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
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.
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
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
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.
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
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
The term "quarterly 8%" does not mean that the interest rate is 8% per quarter and 32% per year. Instead, it means that the annual interest rate is 8%, and the interest is applied every quarter (i.e., every 3 months) at a rate of 2% per quarter.
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
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.
Taking 2-3 min's for an problem,seen many vedios in your channel,but SI and CI are much time taking problem's...no tricks... doing like 6 mark 12 mark essays 🙏🙏🙏
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
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
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 .
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🙏
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.
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)
Sir, in 8th question we can also solve using a formula CI - SI = (SI * R)/200, CI = 645 and SI = 600, so CI - SI = 45 45 = (600* R)/200 => 45/3 = R so we easily get Rate = 15%.
Ur Teaching was amazing and easy to understand 🙏but each question getting so much time. and some questions get a lot of time to explain in a huge step don't we have a short cut method to do. in exam we don't have a time to do in a large step to get a answer. We should get around 30 sec for each question to choose the correct answer in a Short cut method
for 2nd question if it takes 15years to become amount 7times if we divide 15 by 7 we gate years to become amount 1time and if we multiply that no by 10 we get years to become amount 10time. pleas correct me if i am wrong .
Sir I have a doubt, In question number 13 you have got a solution of 10% interest , I think it should be 22% because if we take 10% for one year interest will be 50rs and for 2 years it will be 100 only not 220rs. Please reply
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
In ques 1 if the provided quarterly interest rate is 8% than instructor is doing it wrong because the yearly rate of interest would be 8*4= 32 than the answer would be something else.
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.
3rd question answer we can think like this too right? Ans - 15-12= 3% 3% value is 300 ( 3300-3000 ) so 300×4=1200 ( 3%×4= 12% ) and 300×5=1500 ( 3%×5= 15% ) you got the answer 3000-1200 = 1800 3300-1500 = 1800.
Sir watched your all videos , but SI and CI video , that was worst , rest were good. there are tricks like a+b+ab/100 and other , in exams we will be dealing with new problems , we won't be having this much time .
In question 7) you took 7(1/2) per annum as (7.5/12)...similarly the other 12(1/2) as(12.5/12),but in the beginning intro you told to multiply the timeperiod also with 12 if taken yearly then y didnt u multiply the timdperiod with 12 in the 7th problem
Hey sir , you teach well no doubt in it ......but here are few sums which are going above head please guide me what to do I am unable to understand those Ques.!
The answer to the first question is wrong. It says quarterly rate of 8%, that means for 3 months interest rate will be 8%. With quarterly interest of 8% the simple interest amount will be 5200
In question 4 while solving I used BODMAS. So I first solved 2250*4R/100 and 2000*4R/100 and then subtracted 100R - 80R so I got 20R which I used to divide 130, I am getting 6.5% as the answer.
For 2 question we can use one small formula to find no.of years. (N1-1)/T1=(N2-1)/T2. Where N1 and N2 are the no.of times and T1 and T2 are time periods
There is another shortcut. Based on the concept that if a sum doubles in a certain no. Of years, means it has increased by 100%. Similarly, 7 times means increase of 600% in 15 years, and 10 times mean increase of 900% in x years. Now, 600 is changed into 900 by multiplying it by 3/2. To get the answer, multiply 15 by 3/2 i.e. 22.5 years answer. :)
In Question 8 Sir you've mentioned that CI = P + I(last year interest) And we know that last year compound interest is 300 then how come you changed it into 45 and made 300 as a principle value when you wrote there (345 = P + 345)
I think this will help you. The CI2 is 300. CI1 is 345. Diff is 45 and that 45 is taken as a SI of first 1yr. Because at 1yr SI = CI. Then for SI=45 and simplified we will get Rate is 15percentage. I think this is the logic he told.

3rd question answer we can think like this too right?
Ans - 15-12= 3%
3% value is 300 ( 3300-3000 )
so 300×4=1200 ( 3%×4= 12% )
and 300×5=1500 ( 3%×5= 15% )
you got the answer 3000-1200 = 1800
3300-1500 = 1800.

yea i have the same doubt...by dividing interest by four he considered yearly interest Or maybe interest is always yearly no matter what.
@@godwincrasto3709No, I have seen some questions where the interest rate was given quarterly or half yearly. I think they have made a mistake there.

Where are tricks. In all the questions you used formulas only.
respected sir,
in simple interest qno 9
why we couldn't minus the two ( ci-si) rather doing all those things
sir, in question 3 you have taken + instead of - as 8% decrease. Is it intentionally or it's by mistake?

Sir plz can you develop video on data interpretation and data analysis?
Yes please make videos for data interpretation and data analysis
Most awaited dialogue "See how easy it is."
For 2 question we can use one small formula to find no.of years.
(N1-1)/T1=(N2-1)/T2.
Where N1 and N2 are the no.of times and T1 and T2 are time periods
There is another shortcut. Based on the concept that if a sum doubles in a certain no. Of years, means it has increased by 100%. Similarly, 7 times means increase of 600% in 15 years, and 10 times mean increase of 900% in x years. Now, 600 is changed into 900 by multiplying it by 3/2. To get the answer, multiply 15 by 3/2 i.e. 22.5 years answer. :)
This formula helps! Thankyou
In Question 8
Sir you've mentioned that CI = P + I(last year interest)
And we know that last year compound interest is 300 then how come you changed it into 45 and made 300 as a principle value when you wrote there (345 = P + 345)
I think this will help you.
The CI2 is 300. CI1 is 345.
Diff is 45 and that 45 is taken as a SI of first 1yr. Because at 1yr SI = CI. Then for SI=45 and simplified we will get Rate is 15percentage. I think this is the logic he told.
