Question

A shop keeper bought 45 dozen eggs at 25 rs per dozen. Out of these eggs 40 were broken. What price per dozen must he sell the remaining eggs to gain 25 percent on his investment

Answer 1

CP = 5 x 36= 180

total number of eggs = 5x 12= 60

number of broken eggs

= 5/100 x 60

=3

remaining eggs = 60-3 = 57

Now

number of dozen = 57/12 =( 4+ 3/4) dozen

cost of 4 dozen = 48 x 4= 192

cost of 3/4 dozen = 3/4 x 48 = 36

total money = 192 + 36 = 228

gain = 228 - 180 = 48
