Here is the solution for the problem. 3) We need to find the rate of simple interest given the principal amount, the final amount, and the time. Given: Principal (P) = Rs. 12500 Amount (A) = Rs. 15500 Time (T) = 4 years Step 1: Calculate the Simple Interest (SI). The simple interest is the difference between the amount and the principal. SI = A - P SI = Rs. 15500 - Rs. 12500 SI = Rs. 3000 Step 2: Use the simple interest formula to find the rate (R). The formula for simple interest is SI = (P × R × T)/(100). Rearranging the formula to solve for R: R = (SI × 100)/(P × T) Step 3: Substitute the given values into the formula. R = (3000 × 100)/(12500 × 4) R = (300,000)/(50,000) R = 6 The rate of interest is 6%. Comparing this with the given options: A. 3% B. 4% C. 5% D. 6% The correct option is D. The rate of interest is D. 6\%. That's 2 down. 3 left today — send the next one.
