If in a scheme the word 'FATHER' is coded as '104', how will the word 'MOTHER' be coded in the same scheme?
A104
B83 ✓ Correct
C87
D102
Correct answer: (B) 83 — The word MOTHER is coded as 83, so that is the answer.
Explanation
★The word MOTHER is coded as 83, so that is the answer.
★Each letter is given a reverse alphabet value, where a letter at position n becomes 27 minus n.
★For FATHER the reverse values are 21, 25, 7, 19, 22 and 9.
★Adding these gives 104, which matches the given code.
★For MOTHER the reverse values are 14, 12, 7, 19, 22 and 9.
★Adding these gives 83, so MOTHER is coded 83.
