$36^{0}$ $36^0$

Explanation:

Since the % of people is 10. [ Out of 200 people 20 people played Chess so percentage of people played chess will be 10]
Since angle of Circle is $360^{0}$ $360^0$
Hence 10 % of 360 will be 36
so,
$\frac{∠}{360} = \frac{10}{100}$ $angle/360 = 10/100$
or
$∠ = 360 \cdot \frac{10}{100}$ $angle=360*10/100$
or
$∠ = \frac{3600}{100}$ $angle=3600/100$
or
$∠ = \frac{36}{1}$ $angle=36/1$

Hence Sector angle is = $36^{0}$ $36^0$
