Suppose the salary of A = x Salary of B = 42000 – x A spends 75% of his salary and B spends 90% of his salary; Saving of A = 100 - 75 = 25% Saving of B = 100 - 90 = 10% |
As per the question: x × 0.25 = (42000 – x) × 0.1 ⇒ 0.25x = 4200 – 0.1x ⇒ 0.35x = 4200 ⇒ x = 12000 Hence, Salary of B = 42000 – 12000 = Rs.30000 |
