Study the chart carefully and answer the question that follows.

What is the central angle ( in degrees ) corresponding to the age group 38+ to 48 years and 58+ years and above, taken together ?

144

central angle corresponding to the age group 38+ to 48 years and 58+ years and above = \(\frac{30 + 10}{100}\) × 360º

= \(\frac{2}{5}\) × 360º

= 144º
