    Neha earns 30% more than Sneha. Neha saves 40% of her

    salary, while Sneha saves 10%. If the difference in their spending is Rs. 720, what are Neha’s total savings?
    A Rs.7,800 Correct Answer Incorrect Answer
    B Rs.5,950 Correct Answer Incorrect Answer
    C Rs.9,800 Correct Answer Incorrect Answer
    D Rs.3,120 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let Sneha’s income be Rs. 100n

    Neha’s income = 1.3 × 100n = Rs. 130n

    Expenditure of Neha = 0.6 × 130n = Rs. 78n

    Expenditure of Sneha = 0.9 × 100n = Rs. 90n

    So, 90n - 78n = 720

    Or, 12n = 720

    Or, n = 60

    Savings of Neha = 130n - 78n = 52n = 52 × 60 = Rs. 3,120
