In a college, 35% of the students play at least two out of three games- Cricket, Hockey and Football. Football is played by 45% of the students. 15% of the people play both Cricket and Hockey, while 10% of the people play all the three games. If 7% of the students do not play any game, what percentage of the students play only Football?
15%
Using the venn diagram approach
II +III= 35
a+b=20
Hence percentage playing only Football = 45-10-20 =15%
