CorrectNot quiteAnswer B

Correct answer: B

Explanation

  1. Split the 32 carrom players: 8 (with chess only), 5 (with ludo only), 3 (all three) and the rest.

  2. Only carrom =32−8−5−3=16= 32 - 8 - 5 - 3 = 16.

Worth noting

19 forgets the 3 who play all three; they also play carrom. 13 subtracts the 3 twice.
