Question
Initially, a person spends 70% of his salary and saves
the remaining 30%. If his salary increases by 20% and his savings remain unchanged, he finds himself spending Rs. 6,000 more. What was his initial salary?Solution
ATQ,  Let, the initial salary of the person be Rs. '100x'.  Initial expenditure of the person = 0.70 X 100x = Rs. '70x'  Initial savings of the person = 100x - 70x = Rs. '30x'  New salary of the person = 1.20 X 100x = Rs. '120x'  Savings of the person remains the same.  So, 70x + 6000 = 120x - 30x  Or, 90x - 70x = 6000  Or, 20x = 6000  So, x = 300  So, the initial salary of the person = 100x = 100 X 300 = Rs.30,000
