Question
In a certain code language, āMEANTā is coded as
'360' and 'CUMIN' is coded as '42'. What will be the code for āDEMANDā in the same language?Solution
The word is coded as the product of the place value of the first letter and the last letter as per the English alphabetical order. For āMEANTā, Code = Place value of (M X T) Code = 13 X 20 = 360. So, 'MEANTā is coded as '360'. For āCUMINā, Code = Place value of (C X N) Code = 3 X 14 Code = 42. So, 'CUMIN' is coded as '42'. Similarly, for āDEMANDā, Code = Place value of (D X D) Code = 4 X 4. So, āDEMANDā is coded as = 16.
