Kalyan invested an sum of Rs. 12,000 for two years compounded at 5% and 10%, respectively. What is the compound interest (in Rs) at the end of two years?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 1,860.

Compound Interest = P[(1 + R1/100)(1 + R2/100)] - P

Where P is principal, R1 and R2 are rates of interest.

According to the given question,

Compound Interest = 12000[(1 + 5/100)(1 + 10/100)] - 12000

⇒ 12000 × [(21/20) × (11/10) - 1]

⇒ 12000 × [231/200 - 1]

⇒ 12000 × (31/200) = 1860
