Question

The following table shows the modes of transport used by 1000 people.

Mode of transport	Cycle	Bus	Train	Car
Number of people	200	250	500	50

Which pie chart represents the above data correctly?

• A.
• B.
• C.
• D. None of the above

Answer 1

The correct option is C

Mode of transport	Cycle	Bus	Train	Car
Number of people	200	250	500	50

Given, the total number of people is 1000.
We can find the angle of each sector using this formulae:
$\text{Percentage of a sector}=\frac{\text{Number of people in the sector}}{\text{Total number of people}}\times 100\%$

$\text{Percentage of people whose mode of transport is cycle}=\frac{200}{1000}\times 100\%$
$=\frac{1}{5}\times 100\%$
$=20\%$

$\text{Percentage of people whose mode of transport is bus}=\frac{250}{1000}\times 100\%$
$=\frac{1}{4}\times 100\%$
$=25\%$

$\text{Percentage of people whose mode of transport is train}=\frac{500}{1000}\times 100\%$
$=\frac{1}{2}\times 100\%$
$=50\%$

$\text{Percentage of people whose mode of transport is car}=\frac{50}{1000}\times 100\%$
$=\frac{1}{20}\times 100\%$
$=5\%$

Hence, option (c.) is the correct choice.
