Answer 1

The female workers have to pay rupees 90 to the form for their job

Explanation:

according to the question let us consider X to be the number of female worker and 2 x be the number of male worker

Total worker 2x+x= 3x

For all worker,

The total salary that is paid to the worker by the firm= 310x 3x = 930x

For male worker ,

The average salary is 510 rupees

The total salary= 510 xx

For female worker,

Let us consider the average salary to be y

The total salary given= yx

930x = 1020x + yx

- 90x = yx

Or y= -90 rupees

hence the female workers have to pay rupees 90 to the form for their job
