It’s important to exercise your brain as you age in order to stay mentally sharp. One fun way to do this: add brain teasers to your daily routine.

Solving brain teasers is an entertaining pastime that can help you boost mental skills such as concentration, memory and problem solving. Brain games may even combat changes in cognitive skills that occur as you get older.

One beneficial type of brain teaser is a logic puzzle, a game that requires you to use deductive reasoning to figure out a solution to a problem. There are many types of logic puzzles, from cryptograms to sudoku.

Boosting your logic and problem-solving skills can help you with everyday tasks, such as planning a vacation, deciphering the terms of a loan or making a seating chart for your adult child’s wedding.

This in-the-balance brain teaser requires you to use logic, along with visual skills and math, to balance some scales.

1 diamond equals 4 squares, 6 diamonds equals 24 squares, 24 squares equals 16 circles, 16 circles equals 4 triangles, 6 triangles equals 4 triangles. Thus 4 triangles balances the scale.

A good challenge. I enjoyed doing it. Thank you.

The first and third scale cancel each other. So the answer is 2/3 of the diamonds of 4th scale being 4 triangles…

Is anyone interested in a fairly complex logic problem, involving balance scales?

Great brain exercise

I found the lowest number that could be divided evenly by all the groups. That number is 12. I set the green triangle in balance #1 equal to $12, to make it easy to visualize. That makes the 4 blue circles equal to $3 each. In balance #2, you have $6 worth of blue circles, so the red squares are worth $2 each. Continue in this way, and the solution of 4 green triangles which equal $48 is very easy.

4 triangles. I am terrible at mathematics, but pretty good at logic problems. I was asked by my high school (a billion years ago) algebra teacher to be on the team going to the state mathematics contest. I said, “But…” to which he replied, “Oh, I’m not sending you for your math skills, trust me. I’m sending you for your logic skills. You can tell the rest of the team HOW to solve the problem and leave the math up to them”. Our team from a tiny high school in Illinois won 2nd place in the state, competing against huge high schools from Chicago! I love solving logic problems, and actually, most math problems can be reduced to logic problems.

Same as Marie, the answer is 4 but I came up with it in a different way.

Hi, I got 4 a different way- paper and pencil.

6 purple triangles

I also got the correct answer but went about it in a different way.

I didn’t get it right but I appreciated the correct responses so I could see what I did wrong!!

I came up with 4 green diamonds. 6 purple = 24 red; 24 red=8 blue; 8 blue =4 green!!

Answer is 4 triangles will balance scale 4. ( 6 diamonds = 24 squares … 24 squares = 16 circles … 16 circles = 4 triangles )

This took some thought, but I got it right – It was fun!!

I did the math a bit differently, but got the right answer.

It takes 4 circles to balance 1 triangle and 2 to balance 3 squares. It takes 4 squares to balance 1 diamond. There are 6 diamonds which equate to 24 squares. That equates to 16 circles which means 4 triangles are required to balance the diamonds.

4 triangles

1 diamond = 4 squares so 6*4=24 squares

3 square = 2 circles so (24/3)=8*2=16 circles

4 circles = 1 triangles so 16/4=4

Jeannette—I solved the same way! 🙂

I followed the same process.

Les

got correct answer, slightly different process used

I got the correct answer of 4 diamonds, but I went in reverse. Somewhat like Dennis from Sept.

You asked for triangles and the only one is the green and it is measured on blue circles.

I believe the answer to be 4 (green) triangles.

One purple diamond = 4 red squares so 6 diamonds = 24 red squares.

24 red squares = 16 blue circles.

16 blue circles = 4 green triangles

So, 6 purple diamonds = 4 green diamonds?

I worked the same as Dennis.

4 triangles = 6 Diamonds

that is the way I got the right answer.

These are good Brain Teasers..

We are glad you enjoy these Brain Teasers, Thomas! Thank you for the comment.

I got the correct answer 4, but came up with it in a different way.

Me, too. Worked it backwards.

6 diamonds

6

If 1 green triangle = 4 blue circles,

2 blue circles = 1/2 green triangle = 3 red squares.

4 red squares(3+1/3)) = (1/2 or 3/6) green triangle +1/3 = 2/3 green tri. = 1 purple diamond.

6 purple diamonds = 6 x 2/3 green tri. = 4

that was a challenge(!) and fun to get

4 green triangles
