  This Bheja Fry question I came across when searching Internet.

Question 

If        1111  =  R

          2222   =   T

          3333     =   E

Then       4444    =   ???

Answer 

  

I didn't know the answer  !!!

Some reader used his brain and solved the puzzle.

After looking at solution, I thought it was easy.

Let's have a look at    1111.

When we add all the digits, 

            1 + 1  +  1  +  1   =  4  =  fou  '  R  '

Now   2  +  2  +  2  +  2  =  8 =  eigh    '  T   '

Now  3 + 3 + 3  +  3  =  12  =   twelv   '   E   '

Finally,    4  +  4  +  4  +  4  =   sixtee      '   N   '    !!!!!
