    Solution

    ATQ,

    Let the income of 'N' be Rs. '100n'

    Income of 'M' = 1.8 ├Ч 100n = Rs. '180n'

    Expenditure of 'M' = 0.75 ├Ч 180n = Rs. '135n'

    Expenditure of 'N' = 0.85 ├Ч 100n = Rs. '85n'

    So, 135n тАУ 85n = 1170

    Or, 50n = 1170

    Or, n = 23.4

    Savings of 'M' = 180n тАУ 135n = 45n = 45 ├Ч 23.4 = Rs. 1,053
