# The Simple interest on a sum of money for 2 years at 4% per annum is Rs340. Find (i) the sum of Money and (ii) the compound interest on this sum for one year payable half-yearly at the same rate

Hint:

### Use the formula of simple interest to get the principal amount and from that find the compound interest.

## The correct answer is: 171.4 Rs

### Complete step by step solution:

(i) We calculate simple interest by the formula,…(i)

where P is Principal amount, T is number of years and R is rate of interest

Here we have R = 4% ,T = 2 years ,SI = 340 Rs and P = ?

On substituting the known values in (i), we have

Rupees

(ii) We know that compound interest = Total amount - principal amount that is, CI = A - P …(ii)

Here we have …(iii)

Here, we have T = 1 (payable half yearly), P = 4250 , R = = 2% and A = ?

On substituting the known values in (iii), we get

On substituting the known values in (ii), we get

CI = 171.7 Rs
