Meena buys eggs at Rs. 7 for 20 and sells them at 7.20 per dozen. if the profit is Rs. 30, the number of eggs bought by her is​

Answer 1

Cost of 20 egg is Rs. 7

So, cost of 60 eggs= 21

Means, cost of 5 dozen eggs = 21

Cost of 1 dozen = 4.2

Let no. Of dozen of eggs = x

So, total COST Price = 4.2x

Total selling price = 7.2x

Profit= SP-CP

30 = 7.2x - 4.2x

30 = 3.0x, 3x

x = 30/3

x = 10

That means total no. Of eggs is 10 dozen means 10x12 =120 eggs
