Question

Philoid · Accepted Answer

(1) Given: total number of workers = 10000

And central angle for number of workers in construction = 72°

And we know that,

⇒

⇒ No. of workers in construction = 2000

Thus, number of workers in the field of construction = 2000.

(2) We know that,

⇒

⇒ No. of workers in admin = 1000

Thus, number of workers working in administration = 1000

(3) First, let us find the number of workers working in production.

We know that,

⇒

⇒ No. of workers in production = 2500

In terms of percentage,

⇒

⇒ Percentage of workers in production = 25%

Thus, percentage of workers in production = 25%
