Question

What percent of total spending is spent on Tennis?

• A. $12\frac{1}{2}\%$
• B. $22\frac{1}{2}\%$
• C. 25%
• D. 45%

Answer 1

The correct option is A $12\frac{1}{2}\%$

In the given pi-chart measure of central angle of tennis is ${45}^o$

Measure of all central angles is ${360}^o$

Let $S$ be the percentage of money spend on tennis

$S=(\frac{45}{360}\times 100)\%=\frac{5}{40}\times 100=12\frac{1}{2}$
