Solution

The correct option is A Rs. $678.57$
Total amount spent on shirts is $5 \times 450 = 2250$
amount on trousers is $4 \times 750 = 3000$ and on shoes $12 \times 750 = 9000$
Hence total amount spent is $2250 + 3000 + 9000 = 14250$
so average per article is $14250 / 21 = 678.57$
Hence Option A is correct
