Question
‘U’ and ‘V’ invested Rs. 8100 and Rs. 5400
respectively for 5 and 9 months. U retained 30% of his profit after donating the rest. He received Rs. 1890 as his profit. What was the total profit?Solution
ATQ,
Profit ratio of U and V = 8100 × 5 : 5400 × 9 = 40500 : 48600 = 15 : 18 = 5 : 6
U’s total profit = 1890 / 0.30 = Rs. 6300
Each part = 6300 / 5 = 1260 → Total profit = 1260 × (5 + 6) = Rs. 13860
