Question

if the cost price of 8 pens is equal to the selling price of 6 pens find the gain per cent.​

Answer 1

Answer:

=33 1/3 %

Step-by-step explanation:

let the cost price of 8 pens be x

sp of 6 pens = x

cp of  1 pen = x/8

sp of 1 pen =x/6

p = sp -cp

=x/6-x/8=x/24

p%= p*100/cp

=x/24*8/x*100

=100/3%=33 1/3 %
