Previous Year Question (PYQs)
In a school, $70$ play only hockey. $100$ play only football. $30$ play both the games. $150$ do not play anything at all. What is the percentage, rounded to two decimals, of hockey players to total students in the school?
Solution
Students who play only hockey $=70$
Students who play both games $=30$
So, total hockey players:
$70+30=100$
Total students in the school:
$70+100+30+150=350$
Required percentage:
$\frac{100}{350}\times 100$
$=\frac{2}{7}\times 100$
$=28.57%$
