Solution -
CP of 12 oranges = 10
CP of 1 orange = 10/12
SP of 10 oranges = 12
SP of 1 orange = 12/10
Profit = SP - CP
= (12/10) - (10/12)
= (72 - 50) / 60
= 22/60
Profit percentages = (Profit / CP) × 100
= [(22/60) / (10/12)] × 100
= (11/25) × 100
= 44%
Therefore,
The profit percentage is 44%.
Hence,
The correct answer is option (b) 44%.
