At a party each man shook hands with everyone except his wife. There were no handshakes between women. Six married couples attended the party. How many handshakes were there between these 12 people?
Each person shakes hands with 10 other people (everyone except themselves and their spouse). There are 12 people, so the total number of handshakes is:
12 people × 10 handshakes/person = 120 handshakes
However, we counted each handshake twice (once for each person shaking hands), so we need to divide by 2 to get the total number of unique handshakes:
120 handshakes ÷ 2 = 60 handshakes
Therefore, there were 60 handshakes between the 12 people at the party.
so what is the answer?
The answer is 60 handshakes between the 12 people at the party.
60?
Yes, that's correct! There were 60 handshakes between the 12 people at the party.

Curt agrees to play a game with his friend. He will risk half the chips he has in his pocket on the toss of a coin: heads he wins, tails he loses. Chips then go into his pocket or out of it. The game is repeated in eactly the same way. If after 4 tosses Curt has won twice and lost twice then he: a) won chips; b) lost chips; c) broke even; d) could have won or lost chips. (Hint try playing with 80 chips.)
Let's play out the game with 80 chips as suggested in the hint:
- After the first toss, Curt either wins 40 chips (heads) or loses 40 chips (tails).
- After the second toss, Curt either wins 20 chips (heads after tails) or loses 20 chips (tails after heads).
- After the third toss, Curt either wins 10 chips (heads after tails after heads) or loses 10 chips (tails after heads after tails).
- After the fourth toss, Curt either wins 5 chips (heads after tails after heads after tails) or loses 5 chips (tails after heads after tails after heads).
So, if Curt has won twice and lost twice after four tosses, then he either won a total of 45 chips (40 + 5) and lost a total of 45 chips (40 + 5). Therefore, he broke even, and the answer is c) he broke even.

A clock repairman mistakenly switched the hour hand and the minute hand. The hour hand travels with the speed of the minute hand and the minute hand with the speed of the hour hand. The clock is set correctly at 2 P.M., but will proceed to give incorrect times. In time the hands will be facing directly at two numbers in opposite directions (which happens normally at 6 o'clock, but not now). Give the correct time at that
moment.
