Six children – A, B, C, D, E, and F – and four parents...

[mia828]

Quick question on the below IR question from the MGMAT CAT exam. The first line of the solution says "To solve this logic problem, we place the parents and children in their respective groups working from the most to the least restrictive clues. The most restrictive clue states that X is in group 2" - yet I don't see how any of the clues indicate that X is in group 2. Any help?

Six children - A, B, C, D, E, and F - and four parents - W, X, Y, and Z - are split into three groups for a camping trip. The following rules must hold:

Every group must have at least one parent.

E must be in the same group as F.

Y is not in the same group as D or A.

If F is in group 2, then A is in group 1.

No group has more than two children.

A and B must be split among groups 1 and 3.

Based on the information given, identify a parent that could be in group 1 and a child that could be in group 3. Make exactly one selection in each column.

can you post a screen shot of the problem text as well as the solution so we can look into this further?

I agree...I am confused about the answer that the solution gave as well.

[tim]

give us a screenshot and we can help you..

A student above has posted the screenshot.i think the explanation is incorrect.. D can be in group 1 only not in group 3..according to the qs a,d can't be in the same group as y..

I still can't see a screen shot, but I managed to find the question in out database and agree that the question and solution don't match up. I've alerted MGMAT to the issue and hopefully this question will get corrected.

I've been told by MGMAT that this question has been corrected and the correct version should show up in your CAT exams if you've encountered the question. Let me know if that's not the case and I'll look into it further.

I got the exact same question in MGMAT today.

[tim]

That's unfortunate. Please email MGMAT directly and let them know. Be sure to include a link to this thread as well so they can see what the problem is. We on the forums do not have direct control over what goes onto the CAT exams, so we cannot fix any issues that show up on the tests.

Got this again today.

Please get this corrected, it leads to incorrect scoring.

[tim]

Okay, apparently there is some confusion about what I said in my previous post. We on the forums do not necessarily control what is in the materials, so posting complaints here will not get anything done. Please re-read my previous post for how you can deal with this situation.

Hi, guys

This was actually corrected way back when this was originally reported. We added the restriction that X is in group 2 to the question stem - take a look at it again. It's right in the middle there with all the other restrictions.

The correct answer is Group 1 Z and Group 3 D. Someone posted earlier that they thought D should be in Group 1, but E and F have to be in Group 2, which puts A in Group 1, so D has to be in Group 3.

I'm confused as to why that would be the case. The question has also mandated that Y cannot be in the same group as A or D, which would mean D would have to be in Group 1.

Please could you spell out your logic more precisely? Sure, Y can't be with A or D, but Y could go in group 2. Actually, it's easier to start by working out where the children go in this problem, as we have 2 children in each group. For the adults, we have a "spare", since we only need 1 for each group, but have 4 adults.
