Question
Simple interest earned on an amount of Rs.1200 at rate
of R% per annum after 4 years is Rs.384. Find the simple interest earned on an amount of Rs.1500 at rate of (R + 4)% per annum after 3 years.Solution
According to question, => 384 = 1200 × R% × 4 => R = 384/48 = 8 Therefore, required interest = 1500 × (8 + 4)% × 3 = Rs.540
