Question
Vikram allocates his income in the following manner:
20% is spent on essentials. After essentials, he uses 20% of the balance on food. He spends one-fourth of the remaining amount on transport. Following these expenses, he spends 25% of what's left on entertainment. He saves the remaining sum, which amounts to Rs. 45,000. Calculate his total income.Solution
Let the income of Vikram be Rs. '100q'.
Money spent on essentials = 0.20 Γ 100q = Rs. '20q'
Remaining income = 100q β 20q = Rs. '80q' Money spent on food = 0.20 Γ 80q = Rs. '16q'
Remaining income = 80q β 16q = Rs. '64q' Money spent on transport = (1/4) Γ 64q = Rs. '16q'
Remaining income = 64q β 16q = Rs. '48q' Money spent on entertainment = 0.25 Γ 48q = Rs. '12q'
Savings = 48q β 12q = Rs. '36q' So, 36q = 45,000
Or, q = 1,250
Therefore, income of Vikram = 1,250 Γ 100 = Rs. 1,25,000
