A man bought 20 dozens of eggs at 90.00 Ghana cedies a dozen and sold them at 1.20 Ghana cedies a dozen. Find his gain percent

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
