A man bought 8 shirts at ₹550 each,10 pants at ₹1,000 each and 12 pairs of shoes at ₹850 each pair. What is the average expenditure per article?

Correct option is A

Given:

Shirts: 8 at ₹550 each
Pants: 10 at ₹1,000 each
Shoes: 12 pairs at ₹850 each
Total articles = 8 + 10 + 12 = 30

Formula Used:
Average expenditure per article $$=\dfrac{\text{Total cost}}{\text{Total number of articles}}$$​​

Solution:
Total cost
= $$8\times550 + 10\times1000 + 12\times850$$​​
= 4400 + 10000 + 10200 = 24600

Average =$$\dfrac{24600}{30}$$​= ₹820
