How do you get 8oz using a 10oz and a 6oz glass?

Answer 1

Fill the 10oz glass half full

Fill the 6oz glass half full

Pour both the 10oz & 6oz glasses into a new glass, and you get 8oz.

(10 / 2) + (6 / 2) = 8

Fill the 6 ounce glass and pour it into the 10 ounce glass. Refill the six ounce glass and finish filling the 10 ounce glass from it. Now you have 2 ounces left in the smaller glass. Add another full six ounce glass and you have 8.
