Answer» Correct Answer - Option 3 : Rs. 2591.54

Given:

Principal(P) = Rs. 6400

Rate of Interest(r)  = 24%

Time =  1.5 years compounded half-yearly.

Formula used:

If the interest is compounded half yearly, the rate of interest will be halved and time will be doubled.

CI = P [1 + (R/100)]n - P

Calculation:

CI = 6400 [1 + (12/100)]3 - 6400

⇒ 8991.54 – 6400 = 2591.54

On Solving, we get

CI = Rs. 2591.54

The compound interest is Rs. 2591.54
