dishonest businessman professes to sell his articles at cost price but he uses false weight with which he cheats by 10% while buying and by 10% while selling. Find his percentage profit.

Let his C.P = 100
C.P (false ) = 90 ( cheats by 10%)
S.P (false ) = 110 ( cheats by 10% on CP , professes to sell his articles at cost price )

P% = (SP - CP / CP ) * 100 = (20 / 90 )* 100 = [spoiler]22.23 %[/spoiler]
