### Post of the Week

Math Brain Teasers are very much fun to solve. Similarly Logical Brain Teasers are very entertaining and mind refreshing. If one combines logic with fun to create Mathematical and Logical Brain Teasers then there is blast of fun and entertainment.

Here are some challenging brain teasers which will first require you to think of a logical pattern along with Mathematical calculations to reach the correct answer. In each of the following brain teasers one has to find out value of empty circle. This empty circle is surrounded by other numbers. One has to lot some of the Mathematical operations on the numbers around this empty circle to calculate the correct value of empty circle.

Answers of these brain teases along with detailed explanation of each of puzzle is given at the end of this post. Feel free to post your comments about these brain teasers. Do let me know if you would like to see more puzzles of this type by posting your comments in the Comments section of this post.

Below is the answer of 8th Math Picture puzzle published with title Math Brain Teasers for Kids with answers. We have hidden the answer to avoid someone looking inadvertently at the solution. Do select the text below to read the solution.

8. Here the Math Equation in Weight Picture Puzzle are as below

1) Rabbit + Cat = 10Kg

2) Dog + Rabbit = 20Kg

3) Dog + Cat = 24Kg

Subtracting third equation from second equation, we get

4) Rabbit - Cat = 4 Kg

Adding 1st and 4th Equations we get 2*Rabbit = 14Kg => Rabbit=7Kg

So we get from first equation 7Kg+ Cat = 10Kg => Cat = 3Kg

From 3rd Math Equation Dog + 3Kg = 24Kg => Dog = 21Kg

Last equation 7Kg + 21Kg + 3Kg = 31Kg

So the answer is 31Kg

1) Rabbit + Cat = 10Kg

2) Dog + Rabbit = 20Kg

3) Dog + Cat = 24Kg

Subtracting third equation from second equation, we get

4) Rabbit - Cat = 4 Kg

Adding 1st and 4th Equations we get 2*Rabbit = 14Kg => Rabbit=7Kg

So we get from first equation 7Kg+ Cat = 10Kg => Cat = 3Kg

From 3rd Math Equation Dog + 3Kg = 24Kg => Dog = 21Kg

Last equation 7Kg + 21Kg + 3Kg = 31Kg

So the answer is 31Kg
