What is the compound interest on a sum of Rs. 37500 for 4/3 years at a rate of 12% p.a. if the interest is compounded 8-monthly?

Show answer & explanation

Correct answer: B

Explanation

   The correct answer is option 2 i.e. Rs. 6240

Understanding

Application

Given:

P = Rs. 37500

Time = 4/3 years = 16 months

Rate = 12% PA

Since the interest is compounded 8-monthly:

Rate = 12 × 8/12 = 8%

Time = 16/8 = 2

For CI:

A = P(1 + R/100)T

So,

A = 37500 × (1 + 8/100)2

A = 37500 × 27/25 × 27/25

A = 43740

Hence,

CI = 43740 – 37500

= Rs. 6240
