Quite often adults become so busy taking care of family, work, homes that we forget, or just don’t have time, to take care of ourselves. Keeping fit is usually equated with watching our weight, what we eat, and getting plenty of exercise and rest. But there’s another part of our body that requires exercise to stay healthy. It’s our brain. As we get older many adults will experience some loss in memory and other cognitive skills. There are many online brain fitness sites to help combat the degenerative cycle of age. One of these sites is the The Hartford, and they offer the following brain teasers, plus brain puzzles and activities, brain games, brain fitness tips, brain fitness programs and how to build a better brain.
Ready to give your brain a little exercise? See if you can solve the brain teasers below. You’ll find the answers at the bottom of the post. Good luck!
You’re standing at three light switches at the bottom of stairs to the attic. Each one corresponds to one of three lights in the attic, but you cannot see the lights from where you stand. You can turn the switches on and off and leave them in any position. How can you identify which switch corresponds to which light bulb if you are only allowed one trip upstairs?
A man is trapped in a room with only two possible exits: two doors. Through the first door, there is a room constructed from magnifying glass. The blazing sun instantly fries anyone or anything that enters. Through the second door, there is a fire breathing dragon. How does the man escape?
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?
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?
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.)
A – 0 6 8 9 3
B – 15 27 21 10 19
C – 7 1 47 11 17
Turn on the first two switches and leave them on for 5 minutes. After 5 minutes, turn off the second switch, leaving the first switch on. Now go upstairs to the attic. The light that is on is connected to the first switch. A light that is off but has a bulb that is still warm to the touch is connected to the second switch. The light that is both off and cold to the touch is connected to the third switch, which was never turned on.
The man waited for nightfall, and once it was dark, he exited through the door to the room made of magnifying glass.
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!
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.
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.
