Answers
drink orange juice as well as eat apple =16 , eat apple but not drink orange juice =20
Step-by-step explanation:
Total Students = 50
Drink Orange Juice = 30
Eat Apples = A
Like Apple & Oranges Both = B
Like none = 0 ( each student like at least one of them)
=> Total = Oranges + Apples - Apple & Oranges Both
=> 50 = 30 + A - B
=> A - B = 20
Likes only Oranges = Oranges - Both
=> 14 = 30 - B
=> B= 16
A - B = 20
=> A = 20 + B
=> A = 36
drink orange juice as well as eat apple = B = 16
eat apple but not drink orange juice = A - B = 20
