Prove Your IQ Is Above Average With These 27 Questions

Same.

The set is $1.10. One of the items is more expensive than the other by $1. The mind immediately jumps to "well, duh, one is $1, the other 10 cents" - but that would make a difference of 90 cents. So the correct answer is "one item 5 cents, the other $1.05"

The clue is in the word "more". If the ball costs a dollar "more", the statement implies that the ball costs $1 more than the cap alone. They also tell you the total cost is $1.10, which sets the limit on your total of the cost of the two together. So then, taking these two statements into consideration, if you make the cap cost 10cents, the ball costs a dollar "more" than the cap, which would make the total of both $1.20 (cap 10 cents, ball $1.10). But they told you the total is only $1.10. So therefore the cap can only cost 5cents. List it like this: ball - $1.05, cap - 5 cents, total - $1.10 . So now you have the total correct ($1.10), the cap (5cents) and the ball, which costs a dollar more than the cap ($1.05).

AuspiciousTree283, question 20 is not a trick question. It's asking for the next in the sequence. If it had been M T W T F, the chances are high you would have recognised it as days of the week. Starting with the Friday made it harder. - - - Other similar questions are O T T F F S (one two three four five six), F S T F F (first second third fourth fifth) and J F M A M J J (jan, feb, mar, apr, may, jun, jul), or S M H D W (seconds, minutes, hours, days, weeks). These are all very common questions.

AuspiciousTree283, algebra does solve it. B + C =1.1 and B-C=1. Re-arrange the second to B=1+C, an substitute it into the first, 1 + C + C =1.1 This becomes 2C = 0.1, therefore C = 0.05. The value of C is plugged back in, and we get the B = 1 + C = 1 +0.05 = 1.05. Therefore, the Ball costs $1.05 and the Cap is $0.05.
