BRAIN TEASERS WITH ANSWERS
HOW TO DO BRAIN GYM EXERCISES?
As we develop and strengthen our muscles in our bodies by doing physical exercises, we can keep our mind sharp and energetic by doing brain gym exercises. The number of synapses which provide the communication between billions of brain cells in the human brain is directly proportional to our mental capacity, particularly, our brain power. The number of synapses increases rapidly after birth until the age of two years old. That’s why children learn at an impressive speed during early years of their development. However, as they are getting older, synapses in unused areas start losing their efficiency.

VISUAL BRAIN TEASERS
You can test your visual spatial perception and visual intelligence with visual brain teasers in this section.
New Question
New Attention Question: How can you get 30 by placing the balls into the boxes in the following equation?
This question cannot be solved mathematically. Because the sum of three odd numbers cannot be even.
But here the important thing is your attention
When you place the balls numbered with 11 and 13, you will get 24.
Then, if you place the ball numbered with 9 but inverted, you will get 24+6=30.
1.Visual Brain Teaser: Which one is the top view of the tower on the left?
If you look at to the tower from the above, the top layer is orange. So, the answer is definitely not C.
The second purple layer will not be seen from the above because it is the same size with the top layer.
And the third layer won't be seen either because it is smaller size then the top two layers.
The fourth layer will be the next one that's going to be seen from the above around the purple layer.
The last one is going to be the largest and and it is orange.
According to these, the answer is going to be A2. Visual Brain Teaser: A person sees this picture on the left from where he/she stands. So, which image is he/she looking at to see that picture?

BRAIN TEASER QUESTIONS
Brain teasers questions in this section will test your cognitive skills.
IQ development with the questions prepared like puzzles is really fun.
1. Brain Teaser Question: There are two people. How they can divide a cake into two pieces fairly by using a knife only one time?

Therefore, both of them will be satisfied.2. Brain Teaser Question: Now, the clock shows 3:35 pm. If the clock is rotated 90 degrees counterclockwise then what will be the time?
The important point here is that it is being rotated counterclockwise. It means hour hand will be rotated 90 degrees upper and minute hand will go to the right.
So, hour hand shows 12 and minute hand shows 4.
That's why the answer is: 12:20
3. Brain Teaser Question: Frank's father has 5 sons. If the names of his 4 sons are Fefe, Fifi, Fofo, Fufu, respectively, then what would be the name of his 5th son?

Mathematics is boring and difficult for a lot of people. However, there are some questions that everyone enjoys while solving them. For solving the math brain teasers in this section, you will not need even a pen but still it requires your close attention.
Math brain riddles are very effective brain exercises. Frequently solving these questions is really good way for IQ development.
1. Math Brain Riddle: Replace the question mark with a number respecting the equations below. Find the pattern.
If we think that each number on the left is the power of 4.
41=4
42=16
43=64
44= 2562. Math Brain Riddle: Please use all the numbers and equation marks only once and do the correct equation.
3. Math Brain Riddle:Substract 1000, add 40 add 1000 more, add 30, 1000 more, plus 20 plus 1000 and plus 10...
4. Math Brain Riddle: Use only 0 (zero) 3 times and find the number of 6.
We are going to use factorial equations here. 0! (factorial of zero) is equal to 1. So, the equation will be like this:
(0!+0!+0!)! = (1+1+1)! = 3! = 65. Math Brain Riddle: Replace the question mark with the correct number in the equations below. Find the pattern.
After you multiple the numbers, if you sum up all digits of the result you will get the answer.
12x12 = 144, 1+4+4 = 9
23x23 = 529, 5+2+9 = 16
34x34 = 1156, 1+1+5+6 = 136. Math Brain Riddle: A, B, C, D, and E are representing whole numbers different than each other and zero. So, what are those numbers?
There is a five digit number, when it multiplies by 4 it gives again a five digit number but the new number is other way around.
This number is: 21978
A=2, B=1, C=9, D=7, E=87. Math Brain Riddle: There are so many types of questions like the previous one. For example, which 4-digit number gives you the same number with the other way around when it multiplies by 4?
2178 gives 8712 when it multiplies by 4.
8. Math Brain Riddle:Replace the question mark with the correct answer. P.S. It doesn't have to be a number. Think about the places in daily life that these numbers are located like below.
Here is the tip...
In the car, these numbers are located in a place..
You guessed it, right?
Yeap! It's the gearshift lever.
So, the answer must be the letter 'R'.
9. Math Brain Riddle: Find the weights of animals below.
If two bears weigh 120 kg, then one bear is 60 kg
One bear and one rabbit weigh 70 kg and a bear is 60 kg, then a rabbit is 10 kg.
One bear and one rabbit weigh 70 kg, and then a fox is 20 kg.
10. Math Brain Riddle: Find the result of the following equation.
(A+B)=76
-A+B=-38
If you sum up two equations; 2B=38, B=19
If B=19, A=57,
57/19=3
