Answer:
300 students did not like tea.
300 students did not like tea.The total is 900. As 125 like neither tea nor coffee, 775 like one or the other or both.
300 students did not like tea.The total is 900. As 125 like neither tea nor coffee, 775 like one or the other or both.We subtract this from the total number who like tea (600) added to the total number who like coffee (500) in order to find the overlap which gives up 325 i.e. 600 + 500 - 775 = 325
