Answer 2

Given:-

• Interest = 36
• Time (t) = 3 years
• Rate (r) = 3%

⠀

To find:-

• Sum would earn an interest.

⠀

Solution:-

Let,

• the principle sum be x.

⠀

Here,

• Time = 3 years
• Rate = 3% per year
• Interest = 36

⠀

⇛ Simple Interest = P × R × T/100

⇛ 36 = x × 3 × 3/100

⇛ x = 36 × 100/9

⇛ x = 400

⠀

Hence,

• the sum that would earn an interest is 400.
