The income ratio of Aman to Qureshi is 5:7. Both
individuals save ₹900 each. If the ratio of their expenditures is 7:11, determine Qureshi's total expenditure.Solution
Let the income of ‘Aman’ and ‘Qureshi’ be Rs. ‘5x’ and Rs. ‘7x’, respectively. ATQ, {(5x – 900):(7x – 900)} = 7:11 Or, (55x – 9900) = (49x – 6300) Or, 6x = 3600 So, x = 600 Expenditure of ‘Qureshi’ = 7x – 900 = {(600 × 7) – 900} = Rs. 3,300
