A man bought 6 pencils for Rs.5 and sold them at 5 pencils for Rs.6. Calculate his gain percentage30%33%33.33%44%

Step 1: Calculate the cost price per pencil. The man bought 6 pencils for Rs.5, so the cost price per pencil is Rs.5/6 = Rs.0.8333.

Step 2: Calculate the selling price per pencil. The man sold 5 pencils for Rs.6, so the selling price per pencil is Rs.6/5 = Rs.1.2.

Step 3: Calculate the gain. The gain is the selling price per pencil minus the cost price per pencil. So, the gain is Rs.1.2 - Rs.0.8333 = Rs.0.3667.

Step 4: Calculate the gain percentage. The gain percentage is (gain/cost price per pencil) * 100. So, the gain percentage is (Rs.0.3667/Rs.0.8333) * 100 = 44%.

So, the man's gain percentage is 44%.
