Explanation

CP of 6 pencils = 5. CP of 1 pencil = 5/6. SP of 5 pencils = 6. SP of 1 pencil = 6/5. Profit = 6/5 - 5/6 = (36-25)/30 = 11/30. Profit% = (Profit / CP) * 100 = (11/30) / (5/6) * 100 = (11/30) * (6/5) * 100 = (11/25) * 100 = 44%.

AI explanation

The cost price of one pencil is 5/6 dollars, and the selling price of one pencil is 6/5 dollars. The profit per pencil is 6/5 minus 5/6, which equals 36/30 minus 25/30, resulting in 11/30 dollars. To find the profit percentage, divide the profit by the cost price and multiply by 100, giving (11/30 divided by 5/6) multiplied by 100, which simplifies to 44%.
