Q44. A group of 25 students play Hockey, Football and Cricket. 5 play all the three games, 12 play hockey and football only. 13 play football and cricket only. How many of them do not play any game?
(a) 5
(a) 5 of them do not play any game.
5 play all, so 25-5=20
12 plays hockey and football = 20-7=13
13 plays football and cricket, so 13 –(1+8)=4
Thus, 5 of them do not play any game.
