Quote:
Pure milk is worth $1.08 per litre
This price falls in case of mixture of milk and water. If we compare per litre of pure milk and mixture, concentration of milk will be less in the mixture. But by how much?
In 108 cents, we can buy 1 litre milk
In 90 cents, we will buy \(\frac{1}{108} * 90 = \frac{5}{6} litre\)
Therefore, per litre, 1/6 of milk is replaced by water to make the given mixture.
Quote:
A mixture of certain quantity of milk with 16 litres of water
1/6th of total quantity = 16 litre
So, total quantity of mixture = 96 litre
Thus, litres of milk in the mixture = 96-16 = 80 litres.
Hence, A is the correct answer.

\((x+16)*90 = 108*x\)
