Given Total salaries of A and B = Rs 40,000 A spend = 85 % of his salary B spend = 95% of his salary Formula used Income = Expenditure + Saving Calculation Let the salary of A and B be a and b respectively Saving of A = a - 85% of a = 15% of a Saving of B = b - 95% of b = 5% of b Savings are same of both So, 15% of a = 5% of b ⇒ a : b = 1 : 3 So, x + 3x = Rs. 40,000 ⇒ x = 10,000 Salary of A = x = Rs. 10,000 ∴ The correct answer is Rs. 10,000
