Answer 2

The cost of 4 dozen of eggs is ₹120.

Given:

The cost of 3 scores of eggs is ₹150

To Find:

The cost of  4 dozen eggs.

Solution:

We are required to find the cost of 4 dozen eggs.

1 score = 20 unit

Then, 3 scores = 60units

1 dozen = 12 unit

4 dozen = 48 units

The number of units of the egg is directly proportional to the cost of eggs.

The number of units of the egg ∝ cost of eggs

60 units of egg = ₹150   ---------(1)

48 units of egg =  ₹?

Let 'x' be the cost of 48 units of eggs.

48 units of egg =  ₹x      ---------(2)

On dividing equation(2) by equation(1) we get

x/150 = 48/60

x = (150×48)/60

x = 7200/60

x = 120

Therefore, The cost of 4 dozen of eggs is ₹120.
