x Small -> 2 fruits
y Large -> 3 fruits
(1) 210 servings of fruit is not enough information to determine one unique value of how many large or small drinks were served.
210 = 2 * x + 3 * y
It could be x = 15 and y = 60 or x = 30 and y = 50 or many other solutions.
Not sufficient.
(2) y = 0.8 (x+y) this is not enough information to determine how many large drinks were ordered, you will need to know how many total visitors there were.
Not sufficient.
(1) and (2)
total visitors = T
y = 0.8 * T, therefore x = (1-0.8)*T = 0.2 * T
3 * 0.8T + 2*0.22T = 210
T = 75
y = 0.8*75 = 60
You can find one unique value for the number of large drinks, therefore 1 and 2 are sufficient.
Answer C
y Large -> 3 fruits
(1) 210 servings of fruit is not enough information to determine one unique value of how many large or small drinks were served.
210 = 2 * x + 3 * y
It could be x = 15 and y = 60 or x = 30 and y = 50 or many other solutions.
Not sufficient.
(2) y = 0.8 (x+y) this is not enough information to determine how many large drinks were ordered, you will need to know how many total visitors there were.
Not sufficient.
(1) and (2)
total visitors = T
y = 0.8 * T, therefore x = (1-0.8)*T = 0.2 * T
3 * 0.8T + 2*0.22T = 210
T = 75
y = 0.8*75 = 60
You can find one unique value for the number of large drinks, therefore 1 and 2 are sufficient.

T = S+L
S = 2F
L = 3F
L = ?
(1) Total Fruits = (Number of fruits in small smoothie * number of small smoothie) + (Number of fruits in large smoothie * number of large smoothie)
210 = (2F * S) + (3F * L)
There are 2 unknowns and 1 equation. Not sufficient alone.
(Z) L = 80%T
T = S + L
(L/80%) = S +L
There are 2 unknowns and 1 equation. Not sufficient alone.
Together 2 unknowns and 2 equations.
(C) is the answer
S = 2F
L = 3F
L = ?
(1) Total Fruits = (Number of fruits in small smoothie * number of small smoothie) + (Number of fruits in large smoothie * number of large smoothie)
210 = (2F * S) + (3F * L)
There are 2 unknowns and 1 equation. Not sufficient alone.
(Z) L = 80%T
T = S + L
(L/80%) = S +L
There are 2 unknowns and 1 equation. Not sufficient alone.
Together 2 unknowns and 2 equations.
(C) is the answer

Bunuel
Let
S = # of small smoothies
L = # of large smoothies
Each visitor orders exactly one, so total visitors = S + L
Small = 2 servings, large = 3 servings
Statement (1):
Total fruit servings = 210
2S + 3L = 210
we have many solutions => L=30,S=45 or L=60,S=15
so this is not sufficient
Statement (2):
80% of visitors ordered large smoothies:
L = 0.8(S+L)
this gives ratio of L:S = 4:1,
total visitors can be any multiple of 5. so this is not sufficient
Statment (1) & (2):
L = 4x, S = x, total = 5x
substitute in 2S + 3L = 210
2x + 12x = 14x = 210 => x = 15
Both are sufficient
Option C
