Let the amount of 1 % milk be x quarts and the amount of 4 % milk be y quarts.

Now,

The amount of 1 % milk mixed with the amount of 4 % milk to obtain 10 quarts of 2% milk.

That is,

The equations formed are:

and

Subtract equation (i) from equation (ii):

Hence,

203 quarts of 1% milk is mixed with 103 quarts of 4% milk to obtain 10 quarts of 2% milk.
