Question

A sum of money at a simple interest amounts to Rs. 815 in 3 years and to Rs. 854 in 4 years. What is the sum?

• A. Rs.698
• B. Rs.700
• C. Rs.650
• D. Rs.715

Answer 1

The correct option is A

Rs.698

S.I. for 1 year = Rs. (854 - 815) = Rs. 39.

S.I. for 3 years = Rs.(39 $\times$ 3) = Rs. 117.

Principle = Total sum in 3 years - S.I. earned in 3 years = Rs. (815 - 117) = Rs. 698
