An apple seller bought 60 apple at 50 each,one third of them spoilt before she could sell them. She then sold the restart 80 each.find her profit or loss

Cost of 60 apples at 50 each = 60 * 50 = 3000

1/3 of the apples spoilt = 60 / 3 = 20

Remaining apples to sell = 60 - 20 = 40

Cost of remaining apples = 40 * 50 = 2000

Total cost = 3000 - 2000 = 1000

Revenue from selling the remaining 40 apples at 80 each = 40 * 80 = 3200

Profit = Revenue - Cost = 3200 - 1000 = 2200

Therefore, the seller made a profit of 2200.
