Question
P spends 30% of his income to
groceries, another 30% to rent, and 40% of what is left to bus fare. If his sole expenses are groceries, rent, and bus fare, and he saves ₹600, what is his total income?Solution
ATQ,
Let P’s total income be Rs. ‘100p’ Amount spent on groceries = 100p × 0.3 = Rs. 30p Remaining amount = 100p – 30p = Rs. 70p Amount spent on rent = 70p – 30p = Rs. 40p Amount spent on Bus fare's = 40p × 0.4 = Rs. 16p Savings of P = 40p – 16p = Rs. 24p So, 24p = 600 Or, p = 25 So, income of P = 25 × 100 = Rs. 2,500
