Find his expenditure in the month of July.​

Answer 1

Answer:

Rs.2450

Step-by-step explanation:

Total expenditure from January to December

= Rs. (2800"12) = Rs.33600

Total expenditure from January to July

= (2450*7) = Rs.17150

Total expenditure from July to December

= (3150*6) = Rs. 18900

His expenditure in the month of July

= Rs{(17150+18900)- 33600}

= Rs. 2450
