windfall points

by sanju09 » Sat Jul 10, 2010 4:24 am
Jerome took five spelling tests in the last marking period. He scored 100 percent in all but one. What was his mean score for the spelling tests in the last marking period?

(1) Jerome's lowest score in the five spelling tests was 80 percent.

(2) A score of 100 percent in the spelling tests mentioned is equivalent to 500 windfall points.

T1=T2=T3=T4=100

(1) Jerome's lowest score in the five spelling tests was 80 percent.

T5=80. So mean core is 480/5 = 96%.

But the since the question is asking for marks. INSUFF

(2) A score of 100 percent in the spelling tests mentioned is equivalent to 500 windfall points.

There is slight ambiguity here:
500 windfall points means score?
If yes, then Answer is C because we know the percentage.
If no, then Answer is E.

1
scores in 4 tests= 100 %
scores in 1 test= 80 %

we cannot find mean score because we know only the % and not the actual score

insuff

2.
we are not aware how much he has scored on 1 test.

but if a person scores 100 % means he gets 500(assumption is that
windfall points is same as score)
insuff

1 and 2
enough

C

What if the language of the question is invariably referring percent as the unit of score, if any?

Is this a made up question? A lot of the questions that you post have an "I made this up myself" feel to them. It's important for you to cite your source so that people know whether to take these questions seriously. (I'm not saying that you can't/shouldn't make up questions for fun, but I am saying that unless you explicitly state that they're not real GMAT questions, you're actually hurting the people who come here to study for the GMAT.)

On the actual GMAT, it's extremely unlikely that random elements, such as "windfall points", would ever be introduced in a statement. The reason why so many people are confused about what constitutes "score" is because of statement (2).

I appreciate your guidelines. Any term that's not properly introduced in the stem, makes no sense in a statement, and that's why the statement is generally taken as insufficient on DS. Confusion is the hall mark of a tricky DS if it's not because of an ambiguity.
