Question

Q. 12 dozen eggs were bought at the rate of rs 9 per dozen. one and half dozen eggs were sold at rs 12 per dozen. what was the gain or loss per cent

Answer 1

one and half = 3/2

CP of 1 dozen eggs = 9

SP of 1 dozen egg = 12

total CP = 12 x 9 = 108
total SP = 12 x 3/2 = 18

SP < CP

so it is a loss

loss = 108 - 18 = 90

loss %
= 90 x 100/108
= 1000/12
= 83.3%

Answer 2

One and half = 3/2

CP of 1 dozen eggs = 9

SP of 1 dozen egg = 12

total CP = 12 x 9 = 108

total SP = 12 x 3/2 = 18

SP < CP

so it is a loss

loss = 108 - 18 = 90

loss %

= 90 x 100/108

= 1000/12

= 83.3%
