If 3 dozen eggs cost rupes 90 . what is the cost of 24 eggs ?

Answer 1

Answer:

3doz=Rs.90

36units=Rs.90

so,

1unit=90/36

Step-by-step explanation:

24units=24×90/36

24 units=Rs.60

2doz=Rs.60

Answer 2

Answer:

1 dozen = 12 eggs

3 dozen = 3×12

= 36 eggs

Now,

Cost of 36 eggs = 90 rupees

cost of 1 egg = 90/36

Cost of 24 eggs = 90×24/36

= 90× 2/ 3 ( 24 and 36 divide by 12)

= 30× 2

= 60 rupees

So the cost of 24 eggs is 60 rupees
