Out of his total income, Sanjay spent 50% on rent, 20%
of the remaining income on groceries, and saved 30% of the income left after his expenses. Find the income of SanjaySolution
ATQ, Let the income of Sanjay = Rs. '100y' Amount remaining with Sanjay after his expenses on rent = 100y - 100y × 0.5 = Rs. '50y' Amount remaining with Sanjay after his expenses on groceries = 50y - 50y × 0.2 = Rs. '40y' Amount saved by Sanjay = 40y × 0.3 = Rs. '12y' If 12y = 36000, So, income of Sanjay = 36000 × (100y / 12y) = Rs. 3,00,000
