Answer:
33.33%
Step-by-step explanation:
Given that CP for 20dozen = 20×90
= 1800
SP = 20×120
= 2400
Gain % = (Gain / CP) ×100
Gain = SP-CP
So is the selling price
Cp is the cost price
Hence Gain = 2400-1800
Gain = 600
Gain% = 600/1800 ×100/1
= 0.333×100/1
= 33.33%
Hence his percentage gain will be 33.33%
Since the question stated that percentage gain is to be calculated, I believe the sell price should be higher than the cost price. Hence 1.20 Cedis would not work so I used 120 Cedis instead. Thanks
