Math Brain Teasers 8:: Lets Get Groovy - Find The Missing Number?

(Edited)

Hey All;

I hope you all are liking the Math Brain Teasers. If there is any feedback you have, I'm open to having them discussed and make changes accordingly to the competition that we are having here on the StemGeeks community daily.

I guess in between some of the Math puzzles got a bit complicated. So this time we have an easy and interesting puzzle to solve. Have a look at the following image and try finding out the missing number that should be replaced by the question mark.

Hint:: I think that I shouldn't be giving any Hint for this Brain teaser as it's a simple one. And giving Hint here will make it super easy, which I don't want it to be.

Math Brain Teasers 7:: Solve The Triangle Puzzle - Solved with Explanation

Let's have a look at the answers and the math/logic involved in finding to:: Solve The Triangle Puzzle? for our SEVENTH Math Brain Teasers 7 Question.

Logic to Solving:: The Triangle Puzzle?

Following is the logic used in solving THe Triangle Math Puzzle. You will need to use the equation::

D = 2xC-(A+B)

as your base to get to find the missing number in the Third Triangle.

where D is the central number that we are looking to find. And **A, B, C ** are the numbers around the triangle in an anti-clockwise direction starting from the top of the triangle. This was the HINT that I had already given with regards to anti-clockwise direction.

Steps to decode Tringle 1 Answer

A = 5 B = 2 C= 7

Equation:: D = 2xC-(A+B)

D = 2*7 - (5+2)

D = 14 - 7 = 7

Steps to decode Tringle 2 Answer

A = 3 B = 2 C= 8

Equation:: D = 2xC-(A+B)

D = 2*8 - (3+2)

D = 16 - (5)

D = 11

Steps to decode Tringle 3 Answer

A = 6 B = 4 C= 1

Equation:: D = 2xC-(A+B)

D = 2 * 1 - (6 + 4)

D = 2 - 10

D = -8

Hence the correct answer to our **Math Brain Teasers 7 :: Solve The Triangle Puzzle = -8
