STEPS TO PREDICT DATE OF BIRTH

You can predict the date of birth of your any colleagues, but you have to follow magical tricks and technique. This technique is completely based on mathematical calculation. Let's discuss the mathematical calculation step by step. 

1. Ask your friend to take the number of month in which they were born. (Examples: January is 1; February is 2; March is 3; April is 4; May is 5; June is 6; July is 7; August is 8; September is 9; October is 10; November is 11 and December is 12). Suppose your friend is born on January month then the number is 1. This number is secret to the person whose date of birth has to be predicted. 
2. Next, ask your friend to double the month number. 
3. Add 5 to it. 
4. Multiply it by 5.
5. Put 0 behind the answer. 
6. Ask them to add their date of birth to their answer. (If your friend is born on 19 January then add 19 to the answer). 

After the mentioned above steps are over, ask them to tell you their final answer. 

Just by listening to their final answer you can predict your friend's birthday. But how? 

Let's follow the next steps to know the secret behind predicting birthday... 

SECRET BEHIND PREDICTING DATE OF BIRTH

• After following the above mentioned steps, ask them to tell you their final answer. And again follow these steps:Mentally subtract 50 from the last two digits of the answer and you will have the date. 
• Subtract 2 from the remaining digits and you will have the month. 

In this way, you can easily predict the date of birth 🐣of your 👭👬👫 friend.

EXPLANATION OF PREDICTING DATE OF BIRTH

Let us imagine I (SRISTI SUMAN) am the student of class 6. My date of birthday is 19th January. Here, month number for JANUARY is 1. Then I would have to work out the steps as follows:
1. Take the month number.                  : 1
2. Double the answer.                        : (1×2) = 2
3. Add 5 to it.                                    : (2+5) = 7
4. Multiply it by 5.                              : (7×5) = 35
5. Put zero (0) behind the answer.        : 350
6. Add the date of birth.                      : (350+19) = 369
Thus, the final answer is 369.
Now, let us see how we can deduct my date of birth from the final answer 369.
We will subtract 50 from the last two digits of the answer369 to get the date. 
Next, we will subtract 2 from the remaining digits of the answer 369 to get the month. 

From the final answer 369, we deducted date(19) and month(1 - January) of birthday i.e. 19th January. Thus, the birthday of Sristi is 19th January. 

With the knowledge of this techniques, you can predict the birthday of thousands of your colleagues.
