Question

A man deposited a sum of money to a bank at 9% simple interest p.a. The total interest
that he will get at the end of 5 years is 1,620. Find the deposited amount. ​

Answer 1

Answer:

let the deposited amount is xRs

the interest of x Rs at 9% interest p.a. for 5 years

is x.5.9/100 Rs=9x/20 Rs

so,

9x/20=1620

9x=1620×20

x=1620×20/9

x=180×20=3600

deposit amount is 3600 Rs

Answer 2

The correct answer is Rs 3600.

Given: Rate of interest = 9%.

Time period = 5 years.

Simple interest = Rs 1620.

To Find: Principle amount.

Solution:

$SI=\frac{PRT}{100}$

Let the principle amount = P.

1620 = $\frac{P*9*5}{100}$

P = $\frac{1620*100}{9*5}$

P = Rs 3600.

Hence, the principle amount is Rs 3600.
