Question
The interest received on investing Rs. (5p + 150) on
simple interest at 15% p.a. for 2 years is Rs. (2p + 240). Find the ratio (p - 90):(p + 60)Solution
ATQ,
Simple interest = Principal × Rate × Time ÷ 100 So, 2p + 240 = (5p + 150) × 15 × 2 ÷ 100 2p + 240 = 1.5p + 45 0.5p = 195 p = 390 Required ratio = (390 - 90):(390 + 60) = 300:450 = 2:3
