Question
The simple interest on a sum of money is 8/25 of the
sum. If the rate of interest per annum is two times of the number of years in numerically. Find the rate of interest.Solution
ATQ, Let assume that Simple interest = 8x Principal = 25x Rate of interest = 2R Number of years = R Simple interest = Principal × Rate of interest × Number of years/100 8x = 25x × 2R × R/100 16 = R2 R = 4%
