Mensa and Womensa...
Consider these three questions from a sample Mensa exam, that had fifteen questions total:
- Which of the lettered designs best completes the following sequence?
[o] [.] (o)
- Sally likes 225 but not 224; she likes 900 but not 800; she likes 144 but not 145. Does she like 1600 or 1700?
- Put the appropriate plus and minus signs between the numbers in the cortrect places, so that the sum total will equal 1.
0 1 2 3 4 5 6 7 8 9 = 1
Hint: No hints...just do your best, as this is an "exam."
Solution Commentary: The trouble with tests like these (and people who take them) is that more than one answer seems possible. For example on the first question, I could see A, C, or D being correct... where "best" is arbitrary and in the eye of the beholder:
[o] [.] (o) (.)
[o] [.] (o) [.] [o] [.] (o) [.] ...
[o] [.] (o) [o] [.] (o) [o]...
For the second question, I'm no "square" but it is close to "liking the larger number"...except for the last clue...so maybe Sally likes the larger number only if they are both greater than 100?
And for the third question, it seems so "obvious" since the numbers are listed in order: 0+1+2-3-4+5-6+7+8-9=1. The real challenge (and subsequent membership in Mensa should require you to insert a sign (+-x/) between each digit to equal each of the numbers 0-10.
