There would be the loss of 15% if a pen is sold for $51 . What should be selling price to gain 20%

Answer 1

Let the selling price to gain 20% be x.

Given that the loss of 15% occurs when the pen is sold for $51, this means that the cost price (CP) of the pen is:
CP = $51 / (1 - 0.15) = $51 / 0.85 = $60

Now, if the selling price is x to gain 20%, then:
x = $60 * (1 + 0.20) = $60 * 1.20 = $ 72

Therefore, the selling price to gain 20% should be $72.
