but not eat opple, 30 drink orange juice and each student life at least one of them. Find
(1) How many drink orange juice as well as eat apple?
(2) How many eat apple but not drink orange juice?
​

Answer 1

(1) 16 students drink orange juice as well as eat apple.

(2) 20 students eat apple but do not drink orange juice.

Total number of students= 50

Number of students drinking only orange juice = 14

Number of students drinking orange juice= 30

So, the number of students drinking orange juice and eating apple both = 30-14 = 16

So, the number of students eating apple only = 50-30 = 20.
