A. 24 B. 32 C. 40 D. 48 E. 56 to buy from two hats, two tshirts, two posters, and two keychainsEvery child has to get different item so we need 3 out of 4 items first in 4C3 = 4 ways Now from every item there are 2 ways to pick the item for one child i.e. Total bways to pick items for children = 4C3 *2 *2 *2 = 4*8 = 32 Answer: Option B

A. 24 B. 32 C. 40 D. 48 E. 56 Hat Tshirt Poster Keychain 4C3 = 4 3! = 6 6*4=24 Alternatively If A gets Hat B gets Tshirt then last one has 4 options = 4 B has three options so total will be 12 Now A has 4 options So the total becomes 12*4 = 48 Two answers... Please help me understand what i am missing

I agree with your solution if that is the case. I assumed they were the same there there are 4 ways to select item 1, 3 ways to select item 2 and 2 ways to select item 3. Or 4X3X2 or 24. I think Veritas should be clearer on if they mean 2 different items or not. There questions are getting a lot **** as I move through the practice tests. Why the hell not right 2 different hats, 2 different posters. I don't get how the whole question is writing poorly.

Giving "Two different shirts" would have been awesome however the question always mentions if the objects are identical so in absence of it you should consider them different and it's not an assumption...

I guess that's just a GMAT quirk that I'll remember. I read the items as being the same and found that to be the difficulty of the question. If you told me you had 2 baseballs, I'd assume they were the same baseball and wouldn't need you to tell me you had 2 identical baseballs. I really see no logic in the GMAT thinking it's necessary to say when things are identical but not to say when things are different. That's an esoteric logic system and I believe has only shown up on Veritas not the GMAT itself. Posted from my mobile device
