?Solution
The logic followed here is:
The sum of the place value of the 1st letter of the 1st word and the last letter of the 2nd word gives the coded number.
'B' is the 1st letter in "BOOK" → Place value of B = 2
'E' is the last letter in "PAGE" → Place value of E = 5
BOOK - PAGE = 2 + 5 = 7
'L' is the 1st letter in "LAMP" → Place value of L = 12
'T' is the last letter in "LIGHT" → Place value of T = 20
LAMP - LIGHT = 12 + 20 = 32
