**HOW TO SOLVE IMPOSSIBLE AND HARD PUZZLES**

Hello Friends Most welcome to this post of my Blog . In this post We are going to discuss some of the puzzles, quizzes , riddles, challenges and brain teaser which are viral in social media such as Face book ,whats app, twitter and Google + etc. which are based on Mathematics directly or indirectly . You also have seen such types of problems mentioned 99.9% Fail , Solve if you are genius like this...

Let us try to discuss and solve some of these Puzzles one by one.

## Puzzle #1

If2 = 6

3 = 12

4 = 20

5 = 30

6 = 42

then 9 = ?

In this problem two steps are missing

**7= ?**

**8 = ?**

and directly asked how 9 = ?

HOW TO SOLVE IMPOSSIBLE AND HARD PUZZLES |

If we multiply 2 with its successor ( the immediate next number) i.e. 3 then we get 2×3 = 6, Similarly multiply 3 with its successor 4 we get 3 ×4 =12 ,4×5 =20 and 5 ×6 =30 ,6×7=42 and ( and the missed numbers 7×8=56,8×9=72 )

and finally we have a formula for this quiz which is (a)×(a+1) ,where "a" is given number.

**The required answer is 9 ×10 = 90**

Now let us move to little bit harder problem below

## Puzzle #2

Look at this problem , To solve such types of puzzles ,1st of all do not count "+" ,"-" or any mathematical sign as it appears. i.e in such puzzles + does not means addition and also - do not means subtraction. we our self have to make a formula to satisfies given results and conditions we have to perform such mathematical operations whose result must be the number given in the right side .

So if we add 20+20 which is 40 and then divide it with 10 we shall get 4,

Similarly So if we add 15+15 which is 30 and then divide it with 10 we shall get 3,

so at last if we add 30+15 which is 45 and then divide it with 10 we shall get 4.5 as answer.

**So the formula for this quiz is a+b = (a+b)/10**

**Puzzle # 3 **

**Here it is given that 6+9 =61**

5+8 = 46

4+7 = 33

3+6 = 22

2+1 = Missing

1+4 = ?

Most of peoples forget to understand that one step has been left intentionally to make us fool or we can say it is the part of their strategy.

### Step 1

If we Multiply 6 ×9 then it is equal to 54 but not equal to the given result 61,

### Step 2

If we add successor of 1st term to the result just obtained then it is equal to 54+(6+1) = 61. yes it is , but is it true for next step.

5×8=40 , adding 1st term's successor to the result just obtained i.e 6

5×8+(5+1)=40+6=46, yes it worksNow let us verify for remaining steps

4×7+(4+1) = 28+5 =33 , ok

3×6+(3+1)=18+4=22 , it is ok for all given results

So we have discovered the trends

1 Multiply both the given numbers

2 Add the successor of the 1st number to the result obtained in step 1 ,and we have our answers every time in this puzzles,

.

.

So using the formula so discovered the required term must be 1×4+(1+1)=4+2 =6

**Now the formula for this puzzle is a+b = (a×b)+(a+1)**
