Question

The graph above shows the student participation for $4$ school clubs. Each student is allowed to participate in only one club. If the school has $250$ students, calculate the number of students not in any club.

• A. $220$
• B. $90$
• C. $60$
• D. $30$

Answer 1

The correct option is D $30$

Debate $\to 20$, Student council $\to 70$, Orchestra $\to 90$, choir $\to 40$

Hence, total $20+70+90+40=220$

Total students in the school is $250$.

Hence, the number of students not in any club is $250-220=30$.
