# Find Out the Monthly Average Income.

The average expenditure of a man for the first five months is Rs.1200 and for the next seven months is Rs.1300. If he saves Rs.2900 in that year, his monthly average income is:

- Rs.1700
- Rs.1400
- Rs.1500
- Rs.1600

Correct Option is (3)** Rs. 1500**

**Explanation:-**The average expenditure of a man for first five months = Rs. 1200

Therefore, the total expenditure of five months = 1200 x 5

= Rs. 6, 000

The average expenditure of next seven months = Rs. 1300

Therefore, the total expenditure of seven months = 1300 x 7

= Rs. 9100

He saves in a year = Rs. 2900

So, the total income of a man in a year = 6, 000 + 9, 100 + 2, 900

= Rs. 18, 000

Then, the average monthly income of a man = 18, 000/12

= Rs. 1, 500

Hence, the answer is (3) Rs. 1500.
