Question

The pictogram shows the number of pupils who cycle to school. On the whole, what is the percentage of class 2 pupils who cycle to school?

• A. $10\%$
• B. $25\%$
• C. $37\frac{1}{2}\%$
• D. $50\%$

Answer 1

The correct option is D $50\%$

Answer:-

Given:-

Each symbol represents 30 pupils

Converting the data into frequency distribution table:

Class	No. of pupils $\left(insymbol\right)$ $f_i$	Total no. of pupils $f_i\times 30$
1	4	120
2	7	210
3	3	90

$\Sigma f_i=420$

Percentage of class 2 pupils = $\frac{210}{420}\times 100\%=50\%$

D) $50\%$
