Question 86616
Total number of employees = 3000

No: of employees laid off = 12% of 3000

                           = 0.12 * 3000

                           = 360

Let the number of employees in aerospace division = x

Number of employees laid off here = 10% of x

                                  = 0.1x

So the number of employees in agricultural division = 3000 - x

Number of employees laid off here = 15% of (3000-x)

                                   = 0.15(3000-x)

                                   = 450 - 0.15x

Total Number of employees laid off in both = 0.1x + 450 - 0.15x

Thus 0.1x + 450 - 0.15x = 360

==> - 0.05x + 450 = 360

==> -0.05x = 360 - 450

==> - 0.05x = - 90

==> x = -90/-0.05

      = 1800

Thus number of employees in aerospace division = 1800

And number of employees in agricultural  division = 1200
