sp of 10 pencils=cp of 11 pencil=x
so cp of one pencil=x/11
and sp of one pencil is =x/10
profit=sp-cp=x/10-x/11
=x/110
profit %=profit*100/cp
=x*100*11/120*x=
so profit percentage=20%
so cp of one pencil=x/11
and sp of one pencil is =x/10
profit=sp-cp=x/10-x/11
=x/110
profit %=profit*100/cp
=x*100*11/120*x=
so profit percentage=20%

Define x:
Let the cost price of 1 pencil = x
Find the selling price of 1 pencil:
Selling Price of 10 pencils = Cost of 12 pencils
Selling Price of 10 pencils = 12x
Selling Price of 1 pencil = 12x ÷ 10 = 1.2x
Find the gain:
Gain = 1.2x - x = 0.2x
Find the gain percentage:
Gain percentage = gain/cost price x 100
Gain percentage = (0.2x/x) x 100 = 20%
Answer: The profit is 20%
