Answer 2

Answer:

given : selling price of 20 pens  = cost price of 22 pens

to find : profit percent

Here, a = 22 and b = 20, then

we know , gain % = $\frac{cost price - selling price}{selling price} \times$ 100%

Therefore, Gain% = $\frac{22 - 20}{20} \times$ 100%  = 10%

hence profit percentage is 10%
