    Solution

    ATQ,

    Let Tarun’s income be Rs. 100n

    Arjun’s income = 1.7 × 100n = Rs. 170n

    Expenditure of Arjun = 0.5 × 170n = Rs. 85n

    Expenditure of Tarun = 0.7 × 100n = Rs. 70n

    So, 85n - 70n = 1050

    Or, 15n = 1050

    Or, n = 70

    Savings of Arjun = 170n - 85n = 85n = 85 × 70 = Rs. 5,950
