Question

The cost price of 12 pencil to the selling price of 10 pencils.Find the profit percent.

Answer 1

Answer:

Let the cost price of 1 pencil = x

Find the selling price of 1 pencil:

Selling Price of 10 pencils = Cost of 12 pencils

Selling Price of 10 pencils = 12x

Selling Price of 1 pencil = 12x ÷ 10 = 1.2x

Find the gain:

Gain = 1.2x - x = 0.2x

Find the gain percentage:

Gain percentage = gain/cost price x 100

Gain percentage = (0.2x/x) x 100 = 20%

Answer: The profit is 20%
