In a company there were 75 % skilled employees and the remaining unskilled. 80% of the skilled and 20% of the unskilled were permanent. If the temporary employees were 126 find the total number of employees.

• let the total no. of employees=1000x
  hence, no. of skilled employees=75*1000x/100=750x
  and no. of unskilled employees=1000x-750x=250x
  hence, no. of temporary employees=20% of 750x + 80% of 250x=150x+200x=350x
  since, 126 employees were temporary
  hence, 350x=126
  or, x=126/350=9/25
  hence, total no. of employees=1000x=1000*9/25=360.

• Total 480 employees.
  Explanation:Let there be x number of employees
  Skilled employees=3/4*x
  Unskilled employees=1/4*x
  Total temporary employees=1/5(3/4x)+4/5(1/4x)=126
  Solving we get x=480

  (75%*20%+25%*20%)*total employee=126

• Ans 191s
  75% skilled and 25% unskilled and (80/100)*75 + (120/100)*25 = 65 are permanent
  since 126 are temporary and 65 are permanent totally there are 126+65=191 employees.
