- Rs. 17,000
- Rs. 18,000
- Rs. 16,000
- Rs. 15,000

**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.
