Question

john bought 100 eggs for 40 rupees. out of these, four
eggs were found to be broken and he sold the remaining eggs of the rate of 7.50 rupees per dozen. find his gain or less percent.

Answer 1

cost of 100 eggs = 40 rs

cp of 1 egg=40/100

                = 0.4 rs

if 4 are broken remaining egg= 100-4

                                                  = 96 eggs

cp of 96 eggs = 96*0.4

                       =38.4 rs

sp of 12 eggs=7.50

sp of 1 egg= 7.50/12

                  =0.625 rs

sp of 96 eggs=96*0.625

                       =60 rs

as sp > cp

there is a gain

gain=sp-cp

        = 60-38.4

       =21.6

gain|%=( 21.6/38.4)100

          = 56.25%

Answer 2

The RightAnswer=Gain=56.25%
