Question
In a certain code, CAT is written as DBU. How is DOG written in that code?
Options
- EPG
- DPH
- FQI
- EPH
Show the answer and the worked solution
Correct answer: D. EPH
Worked solution
- C → D, A → B, T → U: each letter shifts +1.
- D → E, O → P, G → H, so DOG becomes EPH.
Answer: EPH.
The idea
Line the words up letter by letter and note the shift for each position. A constant shift is the simplest code and the most common.
Shortcut. Check one letter per option: D must become E (drops DPH) and G must become H (drops EPG); FQI shifts by two, leaving EPH.
Common trap. "DPH" — keeping the D because the code DBU already starts with D; every letter moves one step, so D → E.
