Question

not only answer


step by step ​

Answer 1

Step-by-step explanation:

Let CP of 12 pens be x. Thereby SP of 8 pens is also x.

CP of 1 pen = x/12

SP of 1 pen = x/8

Thereby gain = x/8 - x/12 = x/24

Thereby gain percentage = ((x/24)*100)/(x/12)

= (x*12*100)/(x*24) = 50%

Answer 2

Answer:

cost price of 10 pens=selling price of 8 pens

profit =cost price of (10-8)pens=2pens

out of 10 pens,profit 2 pens

out of 100 pens profit 2×100/10 pens=20 pens

so, profit =20%
