The following pie chart shows the distribution of percentage of a certain corporate office employees in vvarious age-groups.
Total number of employees of the corporate office = 2500
Study the pie 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?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 144
Percentage of employees of age 38+ to 48 years = 30%
Percentage of employess of age 58+ years and above = 10%
The total central angle for a pie chart equals 3600.
Each of the sectors bears the same proportion to the central angle, as to their respective data in the question.
Central angle = Total distribution × 3600
Total distribution (38+ to 48 years and 58+ years and above) = 30 + 10 = 40%
Central angle = (40/100) × 3600 = 1440
