Answer 1

Answer:

2400

Step-by-step explanation:

3000+2400=5400

3000-600=2400

Answer 2

Answer: A = 2400, B = 3000, C = 2500

Step-by-step explanation:

let A salary be x

B salary be y : C be z

   x = y - y*20%

  x = 0.8y   ....equation 1

  y = z + z*20%

y = 1.2z........equation 2

given that x+y= 5400.10

                 0.8y+y=5400.1

          y = 5400.1/1.8

    y= 3000

   x= 0.8*3000

    x=2400

    3000 = 1.2z

   z = 3000/1.2

     z = 2500
