Question

A man bought two consignment of eggs. First at 18 per dozen and an equal number at 20 per dozen. He mixed tge consignment and sold tge eggs at 23.75 per dozen find the gain percent?

Answer 1

Rs. 18=12 eggs
Rs.20=12eggs
total c.p. 24eggs=Rs. 38
12 eggs =Rs. 10
then SP of 12 eggs=23.75
so gain 23.75-19=4.75
gain%=4.75/19*100=25%

Answer 2

Answer:

25%

Step-by-step explanation:

Let x be the dozen of eggs of two consignment of eggs each

Cost of x dozen of eggs at rate of 18 per dozen = 18x

Cost of x dozen of eggs at rate of 20 per dozen = 20x

Total CP = 18x+20x=38x

He mixed tge consignment and sold tge eggs at 23.75 per dozen

SP of 1 dozen = 23.75

SP of 2x dozens = $2x(23.75)=47.5x$

Profit = SP - CP = 47.5 x - 38 x

Profit% = $\frac{47.5x-38x}{38x} \times 100$

Profit% = $25\%$

Hence the gain % is 25%
