See if you can solve the brain teasers below. Good luck!
You have a 3 gallon jug and a 5 gallon jug. You need to measure out exactly 7 gallons of water. How do you do it?
Fill the 5 gallon jug with water, pour it into the 3 gallon jug until the 3 gallon is full, leaving 2 gallons in the 5 gallon jug. Now pour out the water in the 3 gallon jug. Pour the 2 gallons of water (in the 5 gallon jug) into the empty 3 gallon jug. Fill the 5 gallon jug. You now have exactly 7 gallons!
You and a good friend go out and have a nice dinner together, and the bill is $25. You and your friend each pay $15 in cash which your Waiter gives to the Cashier. The Cashier hands back $5 to the Waiter. The Waiter keeps $3 as a tip and hands back $1 to each of you. So, you and your friend paid $14 each for the meal, for a total of $28. The Waiter has $3, and that makes $31. Where did the extra dollar come from?
The statement that you and your friend each paid $14 for the meal is misleading and is, in fact, not accurate. The $14 actually includes the meal and the tip. You each paid $12.50 for the meal (half of $25), $1.50 for a tip (half of $3) and each got back $1 in change. Add it all up and it comes to $15 each, for a total of $30.
In this puzzle, three numbers: 16, 14 and 38, need to be assigned to one of the rows of numbers below. To which row should each number be assigned?
(Hint: This is not a mathematical problem. The numerical values are irrelevant.)
The Answer:
The numbers are organized by shape!
In Row A, all the numbers have rounded shapes.
In Row C, all the numbers have linear shapes.
Row B is mix of curves and lines.
Therefore, 16 goes to B, 14 goes to C and 38 goes to A.
