Answer» Let incomes of wife and husband be Rs. 3x and Rs. 7X respectively. SAVINGS of husband = Rs. (3x - 15000) Savings of wife = Rs. (7x - 45000) Ratio of savings = $(\frac{{3x - 15000}}{{7x - 45000}} = \frac{3}{5})$ ⇒ 15x - 75000 = 21x - 135000 ⇒ 6x = 60000 ∴ 3x = 30000 ⇒ 7x = 70000 ∴ Their RESPECTIVE incomes are Rs. 30000 and Rs. 70000 respectively. |
