Out of his total income, Mohan spent 35% on rent, 30% of the remaining income on groceries, and saved 45% of the income left after his expenses.
ATQ, Let the income of Mohan = Rs. '100y' Amount remaining with Mohan after his expenses on rent = 100y - 100y × 0.35 = Rs. '65y' Amount remaining with Mohan after his expenses on groceries = 65y - 65y × 0.3 = Rs. '45.5y' Amount saved by Mohan = 45.5y × 0.45 = Rs. '20.475y' If 20.475y = 40950, So, income of Mohan = 40950 × (100y / 20.475y) = Rs. 2,00,000
