percent gain:(profit)/costeach * 100

100 (15/8 - 5/3) / (5/3) = 12.5 %

To find the gain percentage, we need to calculate the difference between the selling price and the cost price and then express it as a percentage of the cost price.

First, let's calculate the cost price for one lemon:
The man bought 6 lemons for ₹10, so the cost price per lemon would be ₹10/6 = ₹1.67 (approximately).

Next, let's determine the selling price for one lemon:
The man sells 8 lemons for ₹15, so the selling price per lemon would be ₹15/8 = ₹1.88 (approximately).

Now, let's calculate the gain per lemon:
Gain = Selling Price - Cost Price
Gain = ₹1.88 - ₹1.67 = ₹0.21

Finally, let's calculate the gain percentage:
Gain Percentage = (Gain / Cost Price) * 100
Gain Percentage = (0.21 / 1.67) * 100 ≈ 12.57%

Therefore, the man's gain percentage is approximately 12.57%.
