Question

3) Find the Interest on Rs. 1700 for 2 years at the rate of 10 p.c.p.a.​

Answer 1

Solution!!

The concept of simple interest has to be used here. The principal, rate of interest and time is given in the question. We have to find the simple interest.

Principal (P) = Rs 1700

Rate of interest (R) = 10%

Time (T) = 2 years

You should know the formula to find the simple interest to solve this.

Interest = (P × R × T)/100

Interest = (1700 × 10 × 2)/100

Interest = 17 × 10 × 2

Interest = 17 × 20

Interest = Rs 340

Hence, the simple interest is Rs 340.

The questioner may ask you to find the amount. So here's a formula to find the amount.

Amount = Principal + Interest
