The logic followed here is as follows, Take the sum of the place value of letters, as per English alphabetical order and subtract the number of letters in the word from the sum. Code= Sum of place value of letters - Number of letters in the word. PLATINUM = (16 + 12 + 1 + 20 + 9 + 14 + 21 + 13) – 8 = 106 – 8 = 98. WHETHER = (23 + 8 + 5 + 20 + 8 + 5 + 18) – 7 = 87 – 7 = 80. NUISANCE = (14 + 21 + 9 + 19 + 1 + 14 + 3 + 5) – 8 = 86 – 8 = 78.
