Aptitude - Simple Interest - Discussion

The answer should be 115.50.

It's very simple:
after one year- net amount will be= principal + interest
=200+(200*5*1)/100=210.

The person paid 100.
So new p is 110, so interest comes out to be=( 110*5*1)/100
=5.5

So total amt to be paid after 1 year gaain is = Rs. 115.50.

115 is correct answer bcoz he had taken 200 for 2 years at 5%

S.I for which become 10 rupees

Total =210 at the end of 1st year
so 210-100=10 rupees

Now P become 100 for next year(S.I) coz he had return 100 rupees already

S.I for 100 in one year at 5% is 5

So TOTAL momey to be paid by him would be

210+105=315 out of which he had return 100

So it becomes 215 , means which contains 100 rupees for sum and 115 rupees are to be paid.

115 is correct

Finally what is the conclusion? is 115 correct or 115.5 correct?

The ans is correct as it is based on simple interest, according to SI interest must be calculated only.

Hi guys its me dharampal singh. There is no confusion at all.

Please read problem carefully, particular problem is about simple interest not about compound interest. Interest has been charge on principle amount only not on interest. So answer is 115. Thanks you.

@All those are supporting 115.50

Given Question: A person takes a loan of Rs. 200 at 5% "simple interest"....

What will be the answer if "compound interest" in the place of "simple interest" in the given question ?

What will the difference in the amount he has to pay, while calculating with "simple interest" and "compound interest"?

Can some one answer my questions please?

You are Right Mr.Mukesh Rai..

I 100% agree with you...

Keep it up

You clear my mind to give good solution

Dear All I am not getting what you are justifying let's have a solution from my end

the person takes loan of Rs. 200 at 5% PA

He returns Rs. 100 at the end of 1 year

Bank will charged interest on Rs 200 for one Year

taht is (200*5*1)/100 comes Rs 10 as interest

But he returned Rs. 100 at the end of the first year hence the total is (90+10=100).

hence still he has taken Rs 110.

Now he clears all his dews at the end of the 2nd year now again Bank will charg interest over Rs 110 for 1 year

Hence interest will be (110*5*1)/100 and taht comes Rs 5.5

hence total amount he has to pay at the end of the 2nd year is (110+5.5 = 115.5)

hence the option D is correct and this given in answer is wrong

115 is correct answer because 10 rupee was remaing from 1 year and for the 2 year the simple interest on 100 rupee will be only 5% so adding 100+remaing year 10+5 % simple interest will be 115
