Question
Out of his total income, Rahul spent 25% on rent, 35% of
the remaining income on groceries, and saved 60% of the income left after his expenses.Solution
ATQ, Let the income of Rahul = Rs. '100y' Amount remaining with Rahul after his expenses on rent = 100y - 100y Γ 0.25 = Rs. '75y' Amount remaining with Rahul after his expenses on groceries = 75y - 75y Γ 0.35 = Rs. '48.75y' Amount saved by Rahul = 48.75y Γ 0.6 = Rs. '29.25y' If 29.25y = 58500, So, income of Rahul = 58500 Γ (100y / 29.25y) = Rs.2,00,000
