SSC CGL - 20 Sep 2025 - Shift 1 • Quantitative Aptitude • Q58

What is the compound interest on a sum of Rs. 12,500 at 15% p.a. in 2 years, if the interest is compounded 8-monthly?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 4137.50.

8 months = 2/3 year ⇒ Time = 2 years = 3 periods (n)

Rate per period =15%×23=10%= 15\% \times \frac{2}{3} = 10\% per 8-month period

Amount (A) = P(1 + R/100)n = 12500 (1 + 10/100)3

= 12500 × (11/10)3

= 12500 × 1331/1000

= 16637.5

CI = A - P = 16637.5 - 12500 = 4137.5
