Given : A milkman mixes 2 liters of water in 11 liters of milk.

To find : What is the amount of milk required if he wants to add 13 liters of water to it​ ?

Solution :

A milkman mixes 2 liters of water in 11 liters of milk.

So, the ratio of milk and water is given by

Milk : Water = 11 : 2

For 13 l of water ,

$\cfrac{2x}{13}=13$

$x=\frac{13\times 13}{2}$

$x=\frac{169}{2}$

Now, the amount of milk required if he wants to add 13 liters of water to it​ is

$A=\cfrac{11}{13}\times \cfrac{169}{13}$

$A=\cfrac{143}{2}$

$A=71.5\ l$

Therefore, the amount of milk required if he wants to add 13 liters of water to it​ is 71.5 liter.
