Question

In a class there are 40 students who play at least one game out of Football, Cricket and Badminton.

What percentage of students play all the three games?

• A. $4\%$
• B. $5\%$
• C. $8\%$
• D. $10\%$

 

Answer 1

The number of students, who plays all the three games $ = x$

Now, $ 9 + 6 + 4 + x + 8 + 2 + 7 = 40$

$\implies x + 36 = 40$

$\implies x = 4$

Percentage $ = \dfrac{4}{40} \times 100\% = 10\%.$

So, the correct answer is $(D).$
