• let x be the sum of salary
  given x/17=45000
  x=765000
  if 3 left
  2500 will be dropped from avg
  45000-2500=42500
  new avg will be
  x/14=42500
  x=595000
  prev avg - new avg=765000-595000=170000

• Sum(17)=45000*17-- 1
  Sum(14)=42500*14--2
  Just Subtract the s(17) and s(14)
  S(17)-S(14)=170000

• summation of sal. of 17 teach =x
  summation of sal. of 14 teach =y
  x/17=45000 therfore,x=765000
  y/14=2500 therefore ,y=35000
  ans=765000-35000 =730000
