If GOLD is coded as HOME, COME is coded as DONE and CORD is coded as DOSE. How would the word SONS be written in that code language?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → TOOT
Compare each word with its code letter by letter and see how far each letter moves in the alphabet.
GOLD → HOME: G+1 = H, O stays O, L+1 = M, D+1 = E
COME → DONE: C+1 = D, O stays O, M+1 = N, E stays E
CORD → DOSE: C+1 = D, O stays O, R+1 = S, D+1 = E
So the rule is: every consonant moves one letter forward and every vowel stays as it is
SONS → S+1 = T, O stays O, N+1 = O, S+1 = T, giving TOOT
Tip: Test a coding rule on every example given. A rule by position (+1, no change, +1, +1) fits GOLD and CORD but not COME, whose last letter E stays; only the consonant–vowel rule fits all three.
