Question
Rs. x is invested at simple interest at 8% per annum
for 3 years. If instead Rs. (x + 500) is invested at the same rate for the same period, the total interest received from both deposits is Rs. 1320. Find the value of x.Solution
ATQ, SI = PNR/100 SI = x * 8 * 3/100 SI = 0.24x SI = (x + 500) * 8 * 3/100 SI = 0.24x + 120 (0.24x + 0.24x + 120) = 1320 0.48x = 1320 - 120 0.48x = 1200 x = 1200 / 0.48 x = 2500
