In a certain code, 'sun is hot' is written as 'ka li mo', 'hot tea now' is written as 'mo ra pe', and 'sun tea cup' is written as 'ka ra zu'. Which word is the code for 'hot'?
The code for 'hot' is 'mo'. The word 'hot' appears in the first two statements, and the only code appearing in both is 'mo'. The codes 'ka' and 'ra' are shared by other pairs of statements and stand for 'sun' and 'tea'.
- Aka
- BmoCorrect
- Cra
- Dli
Explanation
'hot' is common to the first two statements, and the common code is 'mo'. 'sun' is common to the first and third, giving 'ka'; 'tea' is common to the second and third, giving 'ra'. So 'ka' and 'ra' are codes for sun and tea, not hot.
