What is the code for 'sky' in the code language ?

Statements:

1. In the code language, 'sky is clear' is written as 'de ra fa'.

2. In the same code language, 'make it clear' is written as 'de ga jo'.

  • A.1 alone is sufficient while II alone is not sufficient
  • B.2 alone is sufficient while I alone is not sufficient
  • C.Either 1 or 2 is sufficient
  • D.Neither 1 nor 2 is sufficient

Answer: D

Correct answer: Neither 1 nor 2 is sufficient

The two statements share only the word ‘clear’, and comparing them shows ‘de’ must be its code. That leaves ‘ra’ and ‘fa’ standing for ‘sky’ and ‘is’ in some order, with nothing to distinguish them. A third statement containing one of those two words but not the other would be needed.
