Answer»

25 %   will be the gain PERCENTAGE .

Step-by-step explanation:

let the cost of ONE pencil be c ,

cost of 5 pencil = 5c

selling price of 1 be s ,

selling of 4 pencil = 4s

5c = 4s  

c = 0.8 s

gain PERCENT  = s - c / c

                   =  s -0.8 s / 0.8 s  

                = 0.2 / 0.8  * 100

             = 25 %
