Hi sandipgumtya,

What is the source of this question (and is it from a GMAT book or a general math book?)? I ask because this question is not written in proper GMAT style and includes some vague information ("F is G's brother" - does that mean that G is a male or a female?; "A hates H and is a male" - so is H a male or a female?").

There are plenty of sources for legitimate GMAT practice material, so I suggest that you spend your time working with those materials.

Hi Sandip,

This questions 'feels' more like an LSAT Logic Games questions than a GMAT question; regardless, you won't see anything this complexly-worded (or vaguely worded) on the Official GMAT.

If the details were a bit clearer (and since the answers choices are relatively small), I would 'map out' all of the options. For example, if we call the females X, Y and Z, since we know that AT LEAST 2 females much be on each team of 5 people, each team is going to be based on one of the following:

XY _ _ _
XZ _ _ _
YZ _ _ _
XYZ _ _

From here, I'd use the various rules regarding the males to map out each 'sub'-option.
