Question
The simple interest on Rs. (6p + 300) at 25% p.a. for 2 years is Rs. (2p + 350). Find the ratio (p - 100) :(p + 50)
Solution
ATQ, Simple interest = Principal × Rate × Time ÷ 100 So, 2p + 350 = (6p + 300) × 25 × 2 ÷ 100 Or, 2p + 350 = 3p + 150 Or, p = 200 Required ratio = (p - 100) :(p + 50) = (200 - 100) :(200 + 50) = 100:250 = 2:5
