price of 1 dozen pencil is 120
price of 1 pencil is 120/12=10
1 dozen = 12
the poor boy buy 2 pencil for 16 rupee
and 1 pencil for 16/2=8
cost price of 2 pencil is 20
selling price of 2 pencil is 16
cost price > selling price = Loss
shopkeeper has a loss of 20-16=4rupees
loss percentage = number / total × 100
4 / 20 × 100 = 20 percentage
