Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. Rs. 6681.6.

Sum, P = Rs 9000

Rate = 32%

Time = 2 years

Amount = P(1+R100)TP({1 + { R \over 100}})^T

Compound interest = Amount - sum of money

According to the given question,

 Amount = 9000(1+32100)29000({1 + { 32 \over 100}})^2

⇒ 9000×132100×1321009000 \times {132 \over 100} \times {132 \over 100} = 15681.6

Interest = 15681.6 - 9000 = 6681.6

Hence the compound interest is Rs 6681.6.
