SSC CGL - 7th March 2020 Shift 1 • Quantitative Aptitude • Q67

The simple interest on a sum of Rs.50,000 at the end of two years is Rs.4,000. What would be the compound interest on the same sum at the same rate for the same period?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. Rs.4,080.

Understanding/Application

p = Rs. 50000

i = Rs. 4000

t = 2 years

i = P×R×T/100

4000 = 50000(r)(2)/100

r = 4%

C.I. = p(1 + r/100)t - p

= 50000(1 + 4/100)2 - 50000

= 50000(26/25)2 - 50000

= 54080 - 50000

= 4080
