Any other way to do this besides the formula?

Hi

TheMastermind ,

This question can be solved as follows:

All you need to know is the formula for three items :

Total - Neither = A+ B + C - (Exactlly two) - 2(Exactly three);Looking at Statement 1, I can say we should take some total value in such a way that 1/3 or 1/2 or 3/4 always give an integer value. I can take the value as 60.

So, total we are taking = 60. We are also given that Neither = 0 (everyone takes atleast 1)

Suppose,

A : cupcakes

B: apple pie

C: ice cream sundaes

Statement 1: A = 20

B = 30

C = 45.

Or substituting the value in the formula, we have

60 - 0 = 20+ 30 + 45 - (Exactly two) - 2(Exactly three)

In order to find out Exactly two, we need exactly 3 in the above equation. Since we dont have that value, we can say Statement 1 is insufficient.

Statement 2: We have exactly 3 here but not any other thing. Hence, insufficient.

Combining, We know exactly 3 now, we can substitute this value in Equation above and get exactly 2. Hence, sufficient.

I hope that makes sense.

Feel free to reach out in case of any concern.
