Hi Guys,
I was going thru Math tips and came across the following :
1. The Lone Wolf
A lone wolf question almost always has a free standing number(or numbers), and a more complex looking equation as the other option. For e.g.
"On a loan, evil necromonger charges X% interest in the first year, and Y% interest in the second. If he loaned Rhyme 20,000$ in 2006, how much Rhyme pay by interest in 2008?"
A) X = 10
B) (X + Y + XY/100) = 100
You can almost be certain, that in such questions, your equations to the stem will reduce to a form that looks like (B), so (A) is actually redundant. Be careful of lone wolves because they will bite you in the posterior if you choose (C).
If you notice a lone wolf question, and you have no clue on how to solve the problem, choose (B) (or whichever is the complex equation).
*as a side note, a wolf, contrary to the popular belief, is a very social mammal and is not at all a loner.
Why isnt the answer C here ? If we have X then only we can solve (B).
Another Query :
If the membership of the drama club and music club are combined, what % of the combined membership will be male?
(1) of the 16 members of the drama club 15 are male
(2) of the 20 members of the music club, 10 are male
I know answer iS (E) as its overlapping sets question. But imagine if they also said there are 5 members in both clubs
in any choice and if this was a PS ques then what would we do ?
Drama : 15 male - 5 male members = 10
Music : 10 male.
Total : 20 / 16+20 or 20/36 * 100. Am I correct ?
Help willbe appreciated.
thanks,
GR
