Question
In a certain code language, if ‘CAREFUL’ is coded
as '29', 'PLATFORM' is coded as '51', then what is the code for ‘GROUND’ in the same code language?Solution
The logic followed here is as follows: The words are coded as the sum of the positional values of the 1st, 4th, and 6th letters from the left end as per the English Alphabetical series. For CAREFUL: Sum of C(3) + E(5) + U(21) → Sum of (3 + 5 + 21) = 29. For PLATFORM: Sum of P(16) + T(20) + O(15) → Sum of (16 + 20 + 15) = 51. Similarly, For GROUND: Sum of G(7) + U(21) + D(4) → Sum of (7 + 21 + 4) = 32.
