Question

If the matches played by Australia are represented in a pie chart, what will be the angle subtended by the matches played between Australia and Canada?

• A. 10°
• B. 20°
• C. 30°
• D. 40^o

Answer 1

The correct option is D

40^o

Total number of matches played by A =

$\begin{array}{c}51\\ 41\\ 42\\ 55\\ 64\\ 32\\ 15\\ 73\\ 90\\ 39\\ 502\end{array}$

Number of matches played between A & C = 41 + 15 = 56.
$502\to {360}^{\circ }$
$56=56\times \frac{360}{502}={40}^{\circ }$.
