Question
P earns Rs. 12,000 per month. He
spends 40% of his income on rent, 25% of the remaining amount on food, and saves the rest. Q saves 20% more than P, and Q's total expenses amount to Rs. 7,020. What is Q's total income?Solution
ATQ,
Amount spent by P on Rent = 12000 × 0.4 = Rs. 4,800 Remaining income = 12000 – 4800 = Rs. 7,200 Amount saved by P = 7200 × (1 – 0.25) = Rs. 5,400 So, amount saved by Q = 5400 × 1.2 = Rs. 6,480 Therefore, income of Q = 6480 + 7020 = Rs. 13,500
