Question

Among 110 students 70 students drink tea and 30 drink coffee and 15 students drink nothing. How many drink tea only. Please I need the fuLL process​

Answer 1

65

Explanation:

There are 110 students in total

15 of them drink nothing so we have 95 students who drink either tea or coffee or both drinks

70 drink tea

30 drink cofee

70+30 = 100 but we have 95 students so 5 students actually drink both drinks

therefore to find how many drank tea only we subtract the amount who wrank both drinks,70-5 = 65
