In a certain code language, STAR is coded as 55 and CUT is coded as 42. How will 'PEN' be coded as in that language?

**********************************************************

THE LOGIC FOLLOWED HERE IS:

PLACE OF LETTERS - (NO OF LETTERS - 1 )

AS

STAR

19 + 20 + 1 + 18 - (NO OF LETTERS -1)

= 58 - (4 - 1)

= 58 - (3)

= 55

CUT

3 +  21 + 20 - (NO OF LETTERS -1)

= 44 - ( 3 - 1)

= 44 - 2

= 42

SIMILARLY

PEN

15 +  5  + 14 - (NO OF LETTERS -1)

= 35 - (3 - 1 )

= 35 - 2

= 33
