Find the compound interest on a sum of ₹50,000 at the rate of 6% per annum to be compounded half yearly at the end of 2 years. (Approximate to the nearest integer.)

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. ₹6,275

We know the formula for value after compound interest is =  P × (1 + R/n)nt 

Thus Interest received =  Principal After Interest - Principal

Thus, Principal After Interest = (50,000) × (1 + 6(2)(100)6\over{(2)(100)})(2)(2)

= (50,000) × (1.03)4

~ 56,275

Interest = 56,275 - 50,000 = 6,275
