In a certain code language, 'BOOK' is coded as '47', and 'PEN' is coded as '38'. How will 'NOTEPAD' be coded in that language?

82

The logic followed here is :

SUM OF PLACE VALUE + NUMBER OF LETTERS IN WORD  = GIVEN CODE

BOOK + 4

( 2 + 15 + 15 + 11 ) + 4

43 + 4 = 47

AND

PEN +3

( 16 + 5 + 14 ) + 3

35 + 3 = 38

SIMILARLY

NOTEPAD + 7

( 14 + 15 + 20 + 5 + 16 + 1 + 4 ) +7

= 75  + 7

= 82
