Answer 2

Given:

an egg costs two and a half rupees.

To Find:

How much will one and a half dozen cost?​

Solution:

It is given that the cost of an egg is two and a half rupees, so the cost of one egg can be written as,

Cost of 1 egg= Rs2.5

And we have to find the cost of one and a half dozen, we should know that 1 dozen means a total of 12, so the amount in one and a half dozen will be,

Total quantity= 1.5*12

                      =18

So the cost of 18 eggs will be,

Cost of 18 eggs= Rs2.5*18

                         =Rs45

Hence, the cost of one and a half dozen eggs is Rs45.
