Question

A survey was done with $300$ people to know if people prefer coffee or tea. The given pie chart shows the number of people consuming tea and coffee. Find the number of people drinking coffee per person drinking tea.

• A. $\frac{1}{3}$
• B. $\frac{1}{2}$
• C. $3$
• D. $2$

Answer 1

The correct option is D $2$

Here, the entire circle is ${360}^0$ which represents $300$ people.
${120}^0$ represents the number of people drinking tea “x”.
Hence, $\frac{x}{120}=\frac{300}{360}$.
$x=\frac{300}{360}\times 120$
$x=100$
$100$ people drink tea.
The rest of the people drink coffee “y”.
$y=300-100=200$
200 people drink coffee.
The number of people drinking coffee per person drinking tea $=\frac{y}{x}=\frac{200}{100}=2$
The number of people drinking coffee per person drinking tea is $2$.
