# Calculate Age from Shoe Size m//

I saw the above image floating around in my facebook feed today and was quite amused at how people believe in such plain simple mathematical illusions. So as I was a bit free in office and found this problem to be pretty easy. I found the simple equation and the detailed explanation of the same and posted it as a comment on the post.

My Comment went like this:

Won’t work for the following cases:

1. Your shoe size is greater than 9
2. Your age is greater than 99

And yes it will only work in the year 2012 and not any other. For other years simply use the (birthYear- 1000) instead of 1012.

Also it is not just true for your shoe size but also for the number of nose, eyes, ears you have. Also it works for the current hour number if its less than 10. If its more than 10 then simply use the last 2 digits of the solution. Try it with your cloth sizes as well, just use the last 2 digits. Simple MATH =)

Also here is the full calculation:

Let shoe size be x
Then final number is ${(5*(x)+50)*20 + 1012 - birthYear}$
${= (100*x) + 2012 - birthYear}$
${= X00 + (Your Age in 2012)}$

PS: X00 means put 2 zeroes at the end of X.
Now since your age is mostly going to be a 2 digit number,
Hence, ${X00 + (Your Age in 2012) = A number with last 2 digits equal to your age }$.

Hence proved.

I hope people are more interested in enjoying the math behind these posts than just being amazed by the pointless magic. m//

# Invite all Facebook Friends for Event Bookmarklet

Hello Folks,

A lot of time you end up in this situation where you have created a new Facebook event and would want to invite all your friends to attend that event. If you have a lot of friends then its a real trouble clicking on select for all the friends and then sending the invites.

To solve this problem I have created a small bookmarklet which automates the process of selecting all your friends for inviting to an event just with the click of the mouse button.

First of all Create a Bookmarklet in your Browser. I am stating the steps for Chrome Browser.

1. Right Click on the Bookmarks Bar and Click on Add New Page… [Click Ctrl+Shift+B to open Bookmarks bar if its not there]

2. Give a Name to the Bookmarklet.

3. In the URL Section enter the following code.
`javascript: var field = document.getElementsByName("checkableitems[]");for (i = 0; i < field.length; i++)field[i].checked = true ;`
4. Hit OK and your Bookmarklet will show in your Browser Bar.

Following are the steps to invite all your friends to an event. Lets consider the event Youth 2 Business – IIT Kharagpur

• Go to the Event Page https://www.facebook.com/event.php?eid=231553940227603
• Click on +Select Guests to Invite
• An Invite Friends box will open. Drag the scroll bar to the end of that box. [It will happen slowly as facebook loads all your friends as you scroll to the bottom of the box. Make sure you end only when the box is at the very end of the scroll space as shown in the picture.]

• Click on the Bookmarklet from your browser bookmark Bar.
• All your friends will be selected. Now click on Submit and your invites will be sent.
Also if you want you can try using the bookmarklet at our event Youth 2 Business – IIT Kharagpur . Visit the link to try it out. https://www.facebook.com/event.php?eid=231553940227603
