A man buys 7 shirts at Rs. 300 each, 2 trousers at Rs. 450 each and 1 pair of shoes at Rs. 500 each. What is the average expenditure (in Rs) per article?
1). 210
2). 250
3). 320
4). 350
Total expenditure for 7 shirts = 7 × 300 = Rs. 2100
Total expenditure for 2 trousers = 2 × 450 = Rs. 900
Total expenditure for 1 pair of shoes = Rs. 500
Total amount spent = 2100 + 900 + 500 = Rs. 3500
Total article = 7 + 2 + 1 = 10
Now,
∴ Average expenditure = 3500/10 = 350
