in STEMGeeks2 years ago

Hey All;

Today, I've for you all a Simple Triangle Puzzle to be solved. There is no denying the fact that solving Math problems or puzzles require logic. And in order to solve this Triangle Puzzle you will need to find the logic and then only will you be able to solve this puzzle.

Have a close look at both Triangles which are solved for you. Find the Number which should replace the Question Mark?


I don't want to scare you by saying that you need to find the logic. The logic isn't that complex and just involves simple calculations. Let me give you a hint to solve this triangle picture puzzle.

Hint:: Here is a simple hint to get you started, solving this puzzle. The numbers that are written on the Triangle edges have to be moved in an Anti-Clock direction. This is BIG; Hint that I've given you ALL. Let's see now if you are able to solve this Triangle Math Puzzle.

Math Brain Teasers 6:: Solve the Picture Puzzle? - Solved with Explanation

Let's have a look at the answers and the math/logic involved in finding to:: Solve the Picture Puzzle? for our SIXTH Math Brain Teasers 6 Question.


Logic to Finding; Solve the Picture Puzzle?

  • Step 1:: In order to solve this puzzle, Let us use the following notations::

  • Donut = D

  • Cupcake = C

  • Chocolate = L

  • Step 2 :: By looking at the second equation it will give us::


The Value of One Chocolate i.e. L = 3

  • Step 3:: Let us now try to solve the third equation now::


L = 3 ; found in Step 1

L L * 2 C = 12

6 *2 C = 12/6

C = 2/2 = 1

Hence 1 Cupcake i.e. C = 1

  • Step 4 :: Lets now try to solve the 1st equation to find the value of Donut

C = 1; from Step 3

D * D * C = 16

4 * 4 * 1 = 16

Hence Donut i.e. D = 4

Finally, solve the equation in question with the following::

The Value of One Chocolate i.e. L = 3
1 Cupcake i.e. C = 1
Hence Donut i.e. D = 4

Let's see the equation in Question now::

C + D X L = ?

1 + 4 x 3 = 1 + 12 => 13

Hence the answer to the Math Brain Teasers 6:: Solve the Picture Puzzle? = 13
