Question
Shalini allocates her income in the following manner:
20% is spent on household expenses. After household expenses, she uses 20% of the balance on rent. She spends one-fourth of the remaining amount on travel. Following these expenses, she spends 25% of what's left on personal care. She saves the remaining sum, which amounts to Rs. 18,000. Calculate her total income.Solution
Let the income of Shalini be Rs. '100q'.
Money spent on household = 0.20 Γ 100q = Rs. '20q'
Remaining income = 100q β 20q = Rs. '80q' Money spent on rent = 0.20 Γ 80q = Rs. '16q'
Remaining income = 80q β 16q = Rs. '64q' Money spent on travel = (1/4) Γ 64q = Rs. '16q'
Remaining income = 64q β 16q = Rs. '48q' Money spent on personal care = 0.25 Γ 48q = Rs. '12q'
Savings = 48q β 12q = Rs. '36q' So, 36q = 18,000
Or, q = 500
Therefore, income of Shalini = 500 Γ 100 = Rs. 50,000
