ATQ, Let, the initial salary of the person be Rs. '100x'. Initial expenditure of the person = 0.65 X 100x = Rs. '65x' Initial savings of the person = 100x - 65x = Rs. '35x' New salary of the person = 1.40 X 100x = Rs. '140x' Savings of the person remains the same. So, 65x + 5200 = 140x - 35x Or, 105x - 65x = 5200 Or, 40x = 5200 So, x = 130 So, the initial salary of the person = 100x = 100 × 130 = Rs.13,000
