Question
‘P’ and ‘Q’ invested Rs. 7200 and Rs. 4800
respectively for 9 months and 15 months. P kept 35% of his profit and donated the rest. His remaining profit was Rs. 1890. What was the total profit earned?Solution
ATQ,
Profit ratio of P and Q = 7200 × 9 : 4800 × 15 = 64800 : 72000 = 9 : 10
P’s total profit = 1890 / 0.35 = Rs. 5400
Each part = 5400 / 9 = 600 → Total profit = 600 × (9 + 10) = Rs. 11400
