A restaurant buys fruit in cans containing $$3\frac{1}{2}$$ cups of fruit each. If the restaurant uses 1/2 cup of the fruit in each serving of its fruit compote, what is the least number of cans needed to prepare 60 servings of the compote ?

(A) 7
(B) 8
(C) 9
(D) 10
(E) 12

1 can = 3.5 cups
or, 0.5 cups = 1 serve
or, 1 can =7 serving

for 60 servings,
8 cans = $$8*7 = 56$$

9 cans = $$9*7 = 63$$

One can serves 7 people (1/2 per person * 3.5) So it required 60/7 = 8.5XXX , and since it has to be rounded up. 9 CANs

7/2 cups = 1 can

1/2 cup of each serving. so 7 serving per 1 can.
Least number is 7*9=63 =60 approx

1/2 cup makes one serving, so 3$$\frac{1}{2}$$ or 7/2 cups will make 7 servings.

For 60 servings, we need:-

7*8= 56 servings

and 1 more can would add remaining 4 servings; hence 8+1 = 9 cans are needed.

When the answer is ~8.5 after all the math is done and when the question asks for the "least" # of cans why should I round it to the "higher" number (9)? Makes no sense to me! I sincerely hope this isn't a GMAT type of question. And yes, I picked B and hence the whining

Edit: Oh well, in retrospect, I see what is happening. Since we are needing ~8.5 cans of food to serve 60, the half-can technically means "one full can". Which means 9 cans in total. Gee I hope I don't get such questions on the real deal.

One serving requires 0.5 cups
One can contains 3.5 cups
So one serving requires (0.5/3.5) cans ie. (1/7) cans

1 serving -> (1/7) cans
60 servings -> 60* (1/7)
= 8.5
So minimum no of cans required is 9

Number of cups used in each serving = 0.5 cups

Number of cups in 1 can = 3.5

Number of servings that can be made from 1 can = $$\frac{3.5}{0.5}$$ = 7

Number of cans required to make 60 servings = $$\frac{60}{7}$$= 8.57

Since the number of cans will be a natural number, the least number of cans needed will be 9.
