Answer 1

Answer:

5.625% gain

Step-by-step explanation:

his cp for 1 egg = 40/100=0.4

his sp for 1 egg =7.5/12=0.625

gain = 0.625-0.2=0.225

gain% = (0.225/0.4)*100 = 5.625%

hope it helps u :)

Answer 2

Answer:

Profit%=56.25%

Step-by-step explanation:

CP of 100 eggs= Rs. 40

CP of 1 egg= 40/100= Rs 0.40

Given, SP of 12 eggs = Rs 7.50 [1 Dozen=12]

SP of 1 egg = 7.50/12= Rs 0.625

Clearly the SP of 1 egg is greater than that of the CP of 1 egg, so it's a profit

Profit= Selling Price- Cost Price

        = 0.625-0.40= Rs 0.225

Profit% = (Profit/Cost Price)*100

           = (0.225/0.40)*100

           =  56.25%
