Amount of liquids taken is same, that is one tea spoon. So they will generally contain the same amount of liquid as both coffee and tea glasses were similar in shape and size.

Let x be the volume of a teaspoon. Let y be the volume of coffee that was returned to the coffee cup.

Then x-y represents the amount of coffee in the teacup and x-y also represents the amount of tea placed into the coffee cup.
