Step-by-step explanation:

If Rita buys 5 sarees at an average cost of 2250, she has spent total ₹11,250 (2250 × 5) on those 5 sarees.

If she buys another 3 sarees at an average cost of 2750, she had spent ₹ 8250 (2750 × 3) on the 3 sarees.

She now has bought 8 sarees for a total spending of ₹19500 (11250 + 8250)

Which brings the average price to …

Average cost = Total money spent ÷ No. of sarees

Average cost = 19500 ÷ 8

Average cost = 2437.5

Hence, the average price of all the sarees is ₹2438.
