If ‘ROTTEN’ is coded as ‘52’, ‘RISE’ is coded as ‘23’, then what is the code for ‘FIRE’?

Solution

All consonants are added according to the position in which they occur in alphabetical series. Same is done for vowels. Finally, the absolute difference of both is the code for that word. For ‘ROTTEN’, place value of (R, T, T, N) – place value of (O, E) = (18 + 20 + 20 + 14) - (15 + 5) = 72 – 20 = 52. Similarly, for ‘RISE’, place value of (R, S) – place value of (I, E) = (18 + 19) - (9 + 5) = 37 – 14 = 23. So, code for ‘FIRE’, place value of (F, R) - (Place value of I, E) = (6 + 18) – (9 + 5) = 24 – 14 = 10.
