Bagi yang penasaran, berikut jawabannya :

1. Fill up the three-gallon container and pour it into the five-gallon container. Do it again -- there will be one gallon left in the three-gallon container. Empty the five, pour in the one, fill the three again and pour it into the firve-gallon container -- you have four!

2. Divide the balls into 3 equal groups for 8 = 3, 3 and 2 with 2 balances are needed. first balance: compare the two groups of three. if they are equal, the heavy ball is one of the 2 if they don't balance compare the heavier group and then the second balance will define the heavy ball. for 26 = 9, 9 and 8 with 3 balances are needed. for 80 = 27, 27 and 26 with 4 balances are needed. for 240 = 81, 81 and 80 with 5 balances are needed. Or Put three balls on each side of the scale. If the arms are equal, you know the heavy ball is one of the two remaining. If the arms are unequal, take the three balls on the heavier side, pick two and weigh them against each other.

3. For every hour (i.e.) 60 minutes, the minutes hand travels 360 degrees. So, for 15 minutes, it would have travelled 90 degrees. For every 12 hours, the hours hand travels 360 degrees. So, for every hour (i.e.) 60 minutes, it would have travelled 30 degrees. That means, for another 15 minutes from 3 o' clock, it would have travelled a further 7.5 degrees. So, the angle should be 7.5 degrees between the two hands of clock at 3:15 Or The hour hand will have moved one-fourth of an hour; therefore, there will be 7.5 degrees between the two hands.

4. Pick up 3, one black, one blue, one black or one blue, one black, one blue or (if you're lucky) one black, one black....and then it's only two!

5. To find the way to Truthtown, ask the man, “Which way is your hometown?” Then, go whichever way he points: If he’s from Liartown, he’ll point to Truthtown, and if he’s from Truthtown, he’ll point to Truthtown.
