    Answer: (4) Rs. 15, 000

    Explanation:-
    Let the total monthly salary of a person be Rs. X.

    If a person spends 15 % of his monthly salary on kitchen expenses, 20% on child education, 8% on family insurance and 17% on other miscellaneous expense,

    Then, his total expenses = X x 15/100 + X x 20/100 + X x 8/100 + X x 17/100
    = (15 X + 20 X + 8 X + 17 X )/100
    = 60 X/100
    = 3 X/5
    He save amount = Rs. 6, 000
    Then, X – 3 X/5 = 6, 000
    (5X – 3 X)/5 = 6,000
    2 X/5 = 6, 000
    2 X = 6, 000 x 5
    X = 30, 000/2
    X = Rs. 15, 000

    Then, the total salary of a person is X = Rs. 15, 000.

    Hence, the answer is (4) Rs. 15, 000.
