Question
In a certain code language, ‘K’ is coded as ‘6’
and ‘S’ is coded as ‘30’ then ‘MUL’ will be coded as ____ in the same code language.Solution
The digits of the positional value of the alphabets are added together and then multiplied by 3 to obtain the code. K → (1 + 1) x 3 = 2 x 3 = 6 S → (1 + 9) x 3 = 10 x 3 = 30 M → (1 + 3) x 3 = 4 x 3 = 12 U → (2 + 1) x 3 = 3 x 3 = 9 L → (1 + 2) x 3 = 3 x 3 = 9
