The simple interest accrued on a certain principal is Rs. 1200 in 4 years at the rate of 8 percent per annum. What would be the simple interest accrued on thrice that principal at the rate of 6 percent per annum in 3 years?
A2150
B2050
C2025 ✓ Correct
D2100
Correct answer: (C) 2025
Explanation
The new simple interest is Rs. 2025.
From SI = PRT/100, P = 1200 x 100/(8 x 4) = Rs. 3750.
Thrice the principal is 3 x 3750 = Rs. 11250.
New SI = 11250 x 6 x 3/100.
= 11250 x 18/100 = Rs. 2025.
