Answer 2

Given :

The cost of $4\frac{1}{2}$ liters of milk = $89\frac{1}{2}$  Rupees

To find :

The cost of 1 liter of milk.

Solution :

∵ The cost of  $\frac{9}{2}$  liters of milk =  $\frac{179}{2}$  Rupees

∴ the cost of 1 liters of milk = $\frac{179}{2}$ ÷  $\frac{9}{2}$

                                            = $\frac{179}{2}\times \frac{2}{9}$

                                            =  $\frac{179}{9}$  =  $19\frac{8}{9}$ Rupees

The cost of 1 liter of milk is  $19\frac{8}{9}$ Rupees.
