Question
Out of the total income of Sunita, she spends 35% on
food, 15% on rent and 30% on groceries. Out of the remaining income, she donates 25% in a charity and saves the rest. If Sunita saves Rs. 3,750, then find her income.Solution
ATQ, Let the income of Sunita be Rs. '100x' Amount spent on food = '100x' X 0.35 = Rs. '35x' Amount spent on rent = '100x' X 0.15 = Rs. '15x' Amount spent on groceries = '100x' X 0.3 = Rs. '30x' Remaining income = ('100x' - '35x' - '15x' - '30x') = Rs. '20x' Savings of Sunita = '20x' X 0.75 = 3,750 Or, 15x = 3,750 Or, x = 3,750 ÷ 15 = 250 Therefore, income of Sunita = 100x = 100 X 250 = Rs. 25,000
