Answer:SI=P×R×T/

400×3×6/

=72ans

## Given,

Principal amount, P = Rs 400

Time period, T = 3 year

Rate of Interest, R = 6% p.a.

## To Find,

Simple Interest, SI =?

Formula to be used,

Simple Interest = (P × T × R)/100

## Solution,

We know that,

Simple Interest = (P × T × R)/100

Putting all the values, we get

⇒ Simple Interest = (400 × 3 × 6)/100

⇒ Simple Interest = 7200/100

⇒ Simple Interest = Rs. 72

Hence, the simple interest is Rs. 72.
