In a certain code, CAT is written as 3-1-20 and DOG is written as 4-15-7. Using the same rule, what is the code for the word FISH?

FISH is coded as 6-9-19-8. The code assigns each letter its alphabetical position, as seen in CAT and DOG, so F is 6, I is 9, S is 19 and H is 8.

  1. A6-9-19-8Correct
  2. B6-9-18-8
  3. C7-9-19-8
  4. D6-10-19-8

Explanation

The rule is each letter equals its position number. F=6, I=9, S=19, H=8. So FISH is 6-9-19-8. Option 6-9-18-8 wrongly takes S as 18, which is R's position.
