Question 9

Four friends — J, K, L, M — each prefer a different one of red, blue, green and yellow. K likes blue. J does not like red, blue or yellow. L does not like green. M does not like yellow. Find each person's colour.

Accepted Answer

K = blue (direct clue). J rules out red, blue and yellow, leaving only green — so J = green. With blue and green taken, only red and yellow remain for L and M. M rules out yellow, so M = red, leaving L = yellow (L's 'not green' clue is already satisfied since green is taken by J).

Final: K = blue, J = green, M = red, L = yellow.
