A sum was put at simple interest at a certain rate for 3 years. Had it been put at 1% higher rate, it would have fetched ₹5100 more. Find the sum.

A₹ 1,70,000 ✓ Correct

B₹ 1,50,000

C₹ 1,75,000

D₹ 2,00,000

Correct answer: (A) ₹ 1,70,000

Explanation

The sum is Rs. 1,70,000.

Extra interest comes only from the 1% rate rise over 3 years.

P x 1 x 3 / 100 = 5100.

3P/100 = 5100.

P = 5100 x 100 / 3 = Rs. 1,70,000.
