Fill 3 quartz cup with water, pour it into the 5 quartz cup.
Now 5 quartz cup is 3/5th full
Again fill the 3 quartz cup and fill the remaining of 5 quartz cup using that.
Now 5 quartz cup is full, and 3 quartz cup has 1 quartz water.
Empty the 5 quartz cup and pour the 1 quartz water from 3 quartz cup into the 5 quartz cup.
Fill the 3 quartz again and pour it into the 5 quartz cup which now has (1+3) = 4 quartz
