Answer:
Selling price of 20 pairs of shoes = Rs. 18000
Selling price of 1 pair of shoe = 18000/20 = Rs. 900
Loss % = 20
Therefore,
The cost price of 1 pair of shoe = (100/100 - 20)*900
⇒ = (100/80)*900
⇒ = 4500/4
= Rs. 1125
If gain is 20 %, then the selling price of 1 pair of shoe = 1125 + (1125*20)/100
= 1125 + 225
Selling price of 1 pair of shoe = Rs. 1350
If gain percentage is 20 %, then the selling price = Rs. 1350
Therefore, the number of pair of shoes = 16200/1350
= 12 pair of shoes.
The required number of pair of shoes to be sold are 12
