Question

A sum of money at simple interest amounts to Rs. 815 in 3 years and to Rs. 854 in 4 years. The sum is

• A. Rs. 650
• B. Rs. 690
• C. Rs. 698
• D. Rs. 700

Answer 1

The correct option is C

Rs. 698

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

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

$\therefore$ Principal = Rs. (815 - 117) = Rs. 698
