Question
If in a certain code language “PRODUCT” is coded as
‘320’, ‘LOAFER’ is coded as ‘216’, then, ____ is coded as ‘16’ in the same code language.Solution
The words are coded as the product of the positional value of first and last letter from the left end in the English alphabetical series. PRODUCT → 16 x 20 = 320 LOAFER → 12 x 18 = 216 DEMAND → 4 x 4 = 16
