Find his monthly average income if he saves Rs. 2900 during the year?
The average expenditure of a man for the first five months is 1200 and for the next seven months is Rs.1300. Find his monthly average income if he saves Rs. 2900 during the year
- Rs. 1500
- Rs. 1475
- Rs. 1450
- Rs. 1425
Answer: (1) Rs. 1500
Explanation:-
The average expenditure of a man for the first five months = Rs. 1200
Therefore, the sum of expenditure of money foe the first five months = 5 x 1200
= Rs. 6, 000
The average expenditure for next seven months = Rs. 1300
Therefore, the sum of expenditure of money for next seven months = 7 x 1300
= Rs.9, 100
Then, the total expenditure of a man during the year = 6, 000 + 9, 100
= Rs. 15, 100
He saves in the year = Rs. 2, 900
So, the total income of a year = 15, 100 + 2, 900
= Rs. 18, 000
Then, his monthly average income = 18, 000/12
= Rs. 1, 500
Hence, the correct answer is (1) Rs. 1, 500.
