Question

selling price of 12 pens is equal to the cost price of 14 pens . Find the gain or loss percent​

Answer 1

Step-by-step explanation:

let the cp of 1 pen be x

cp of 14 pen = 14x

sp of 12 pen =cp of 14 pen (given)

sp of 12 pen = 14x

cp of 12 pen = 12x

since sp>cp =gain

gain = sp-cp

gain= 14x-12x

gain= 2x

gain%= gain/cp × 100

gain%= 2x/12x×100 = 50/3%

gain%=16.67%
