Question
A person initially spends 50% of his salary and saves
the rest. After his salary increases by 30%, he continues to save the same amount but now spends Rs. 9,000 more. Calculate his initial salary.Solution
ATQ, Let, the initial salary of the person be Rs. '100x'. Initial expenditure of the person = 0.50 X 100x = Rs. '50x' Initial savings of the person = 100x - 50x = Rs. '50x' New salary of the person = 1.30 X 100x = Rs. '130x' Savings of the person remains the same. So, 50x + 9000 = 130x - 50x Or, 80x - 50x = 9000 Or, 30x = 9000 So, x = 300 So, the initial salary of the person = 100x = 100 X 300 = Rs.30,000
