Profit Percentage =( Profit ∕ Cost Price )×100
Calculation:
Let the actual weight be 100 units.
⇒ Weight used by the shopkeeper =100−21=79 units
Let the cost price (CP) of 1 unit of goods =₹1.
Total cost price for 79 units =79×1=₹79
Selling Price (SP) of 79 units = Selling Price for 100 units (as he promises to sell at cost price).
⇒SP=₹100
Profit =SP−CP
⇒ Profit =100−79=₹21
Profit Percentage =( Profit ∕ CP )×100
⇒ Profit Percentage =(21∕79)×100
⇒ Profit Percentage =26(46∕79)%
