Hi bhavik.shah;
Welcome to the forum!
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Hi;
Maybe he did, but shouldn't we ask that big know it all what exactly his thought processes were. Looks like luck to me!

Re: magic of numbers
Hi bhavik.shah;
Your second method is algebraically the same as my method:
For 3 values a,b,c: Mine is on the left and yours is on the right.
(a + c)b = ab + cb
