Question

Simple interest on a certain sum of money for 3 years at 8% per annum is half the compound interest on . 16000 for
2 years at 10% per annum . The sum placed on simple interest is

Answer 1

Let the sum of money be P

So, the simple interest on P at 8% p.a for 3 years = P*3*8/100 = 24P/100

The compound interest on Rs. 16000 for 2 years at 10% per annum = 16000(1+10/100)2 â 16000 = 19360 â 16000 = 3360

According to the question

24P/100 = (1/2)*3360

24P = 168000

P = 7000
