Question

The cost of dozen eggs is $₹60$. Find the cost of $4$ eggs.

Answer 1

Finding the cost of $4$ eggs:

A dozen eggs cost $₹60$.
Assume the cost of $1$ egg to be $₹x$.
$1$ dozen $=$ $12$ eggs
Cost of $1$ egg $=x=\frac{60}{12}$
$x=₹5$
The cost of $4$ such eggs $=5\times 4$
Therefore, the Cost of $4$ eggs $=₹20$
