Given:

Cost of 11 oranges = Rs. 10

Cost of 10 oranges = Rs. 11

Formula used:

Cost Price (CP) per orange = Total Cost ÷ Number of Oranges

Selling Price (SP) per orange = Total Selling Price ÷ Number of Oranges

Gain Percentage = (Gain ÷ Cost Price) × 100

Calculations:

CP per orange = (10 ÷ 11) = Rs. 0.9091

SP per orange = (11 ÷ 10) = Rs. 1.10

Gain per orange = SP - CP = 1.10 - 0.9091 = Rs. 0.1909

Gain Percentage = (0.1909 ÷ 0.9091) × 100

⇒ Gain Percentage = 21%

∴ The gain is 21%.
