Three companies are working independently and receiving the savings 20%, 30%, 40%. If the companies work combinely, what will be their net savings?

• let each salary be 100
  so together they save 30+40+20=90
  so they save 90 out of total income =300
  so saving %=(90/300)*100

• average of the all these savings 20+30+40/3companies=30%

• suppose total income is 100
  so amount x is getting is 80
  y is 70
  z =60
  total=210
  but total money is 300
  300-210=90
  so they are getting 90 rs less
  90 is 30% of 300 so they r getting 30% discount
