A person takes loan of Rs. 1,50,000 at a compound interest rate of 10% per annum. If the loan is repaid at the end of the 3rd year, what is the total interest paid?

Correct option is D

Given:

• Principal = Rs. 1,50,000.
• Rate = 10% per annum.
• Time = 3 years.

Formula:
Compound Interest = Principal × [(1 + r)^t - 1], where r = rate and t = time.

Solution:

1. Calculate the total amount to be paid:
   A = 1,50,000 × (1 + 0.1)³
   A = 1,50,000 × (1.1)³
   A = 1,50,000 × 1.331 = Rs. 1,99,650
2. Total interest = Amount - Principal:
   Interest = 1,99,650 - 1,50,000 = Rs. 49,650

Final Answer: (d) 49,650
