In a certain code language, 'ROM' is coded as '43', and 'ABK' is coded as '11'. How will 'PNB' be coded in that language?

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

THE LOGIC FOLLOWED HERE IS :

SUM OF THE PLACE VALUE -3

AS

ROM = 18 + 15 + 13  = 46

AND 46 - 3 = 43

SIMILARLY

ABK = 1 + 2 + 11 = 14

14 - 3 = 11

THEREFORE

PNB = 16 + 14  + 2 = 32

AND 32 - 3 = 29
