Download Solution PDFGiven:
By selling 100 pencils, a shopkeeper gains the selling price of 20 pencils.
Formula Used:
Gain % = (Gain / Cost Price) × 100
Calculation:
Let the selling price of 1 pencil be Rs. 1.
Selling price of 100 pencils = Rs. 100
Gain = Selling price of 20 pencils = Rs. 20
Cost Price of 100 pencils = Selling Price of 100 pencils - Gain
Cost Price of 100 pencils = 100 - 20 = Rs. 80
Gain % = (Gain / Cost Price) × 100
Gain % = (20 / 80) × 100
Gain % = 25%
The gain per cent is 25%.
