    Question

    A family spends 40% of their monthly income on rent, 20%

    on groceries, and 15% on utilities. If they save ₹5,400 after these expenses, what is their total monthly income?
    A ₹20,000 Correct Answer Incorrect Answer
    B ₹25,000 Correct Answer Incorrect Answer
    C ₹21,600 Correct Answer Incorrect Answer
    D ₹30,000 Correct Answer Incorrect Answer

    Solution

    Let the monthly income be x. Rent = 0.4x, Groceries = 0.2x, Utilities = 0.15x. Total expenses = 0.4x + 0.2x + 0.15x = 0.75x. Savings = Income - Expenses = x - 0.75x = 0.25x. Given savings = ₹5,400. 0.25x = 5400 → x = 5400 / 0.25 = ₹21,600. Correct answer: C) ₹21,600
