A certain sum amounts to Rs. 9243.20 in 
years at 4% p.a. simple interest. What will be the simple interest on the same sum for 
years at 8% per annum?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Rs. 5232
SI = PRT/100
A = 9243.2, T = years, R = 4%
9243.2 = P + P × 4 × 3/200
9243.2 = 212P/200, P = 8720
Required SI for years at 8% p.a is
SI = 8720 × 8 × 15/200 = Rs. 5232
