Number of Female Workers Above 30 Years

Given that there are 840 female workers above 30 years in the factory.

Percentage of Female Workers

We are told that the remaining workers above 30 years are males. Therefore, the percentage of female workers above 30 years can be calculated as follows:

100% - 60% = 40%

Number of Male Workers Above 30 Years

Since the remaining workers above 30 years are males, we can calculate the number of male workers as follows:

40% x Total number of workers above 30 years = Number of female workers above 30 years
0.4 x Total number of workers above 30 years = 840
Total number of workers above 30 years = 840 / 0.4
Total number of workers above 30 years = 2100

Percentage of Workers Above 30 Years

We are given that 70% of the workers in the factory are above 30 years. Therefore, we can calculate the total number of workers in the factory as follows:

100% = Total number of workers
70% = Total number of workers above 30 years
30% = Total number of workers below 30 years

Let's assume the total number of workers in the factory is x.

70% x = Total number of workers above 30 years
0.7x = 2100
x = 2100 / 0.7
x = 3000

Therefore, the total number of workers in the factory is 3000.
