2. Math magic trick

Math Magic Trick:

Here we will discuss about math magic trick or math tricky questions.

it feels like math magic trick but it is just as math tricky questions.

Ask to someone to choose a number to perform with these successive operations

Step 1 . Multiply the number by 5 .

Step 2.  Add 6 in result of first step.

Step 3.  Multiply by 4 in result of second step.

Step 4.  Add 9 in result of third step.

Step 5.  Multiply by 5 in result of fourth step.

Ask to be told the result in the last step.

For you —

                   Step 1. Subtract 165 from the result.

                   Step 2. Remainder is divided by 100.

The quotient will be the number originally thought.

Explanation –

                         Suppose the selected number is n . Then applies these successive operation

Step 1 . 5n .

Step 2.  5n + 6

Step 3.  20n + 24

Step 4.  20n + 33

Step 5.  100n + 165

For you —

                   Step 1. 100n + 165 – 165 = 100n

                  Step 2. 100n / 100 = n.

Example :

In this puzzle ( or math magic trick or also we can say that math tricky questions ) at least two parties are involved like

A and B.

A” is a performer of this Puzzle (math tricks magic).

B” is a listener of this Puzzle (math tricks magic ).

A asked to B :  You can Choose any number in your mind.

B : OK done ! (  I thought 7  in mind)

A : Multiply  the number by 5.

B :  OK done ! (  Calculation in mind  7 x 5 = 35 )

A : Add 6 in result.

B :  OK done ! (  Calculation in mind   35 + 6 = 41 )

A : Multiply by 4 in result.

B :  OK done ! (  Calculation in mind   41 x 4 = 164)

A : Add  9 in result.

B :  OK done ! (  Calculation in mind   164 + 9 = 173)

A : Multiply  the number by 5.

B :  OK done ! (  Calculation in mind   173 x 5 = 865)

A : Tell me the result in last step.

B : 865

A : 7      { Calculation in mind :

                    865 – 165 = 700 ,

                    Now 700/100 = 7 }

B : Surprised !

Readers  can be also surprised your friends , try this math magic trick with your friend or family members.

At last we say that it feels like magic tricks with number but it is only math tricky questions because original thought disappear due to successive operation.
