Question 137

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

Solution

Average expenditure for the first 5 months = Rs. 1200

=> Total expenditure in first 5 months = $$5\times1200=Rs.$$ $$6000$$

Similarly, total expenditure in next 7 months = $$7\times1300=Rs.$$ $$9100$$

Total savings = $$Rs.$$ $$2900$$

Thus, total annual income = $$6000+9100+2900=Rs.$$ $$18000$$

$$\therefore$$ Monthly average income = $$\frac{18000}{12}=Rs.$$ $$1500$$

=> Ans - (D)
