 ((100-x/100)*(100-y/100)*(100-z/100))*100

                                                                The resultant should be subtracted from 100.

30%..20+30+40 = 90 savings out of 100+100+100 = 300 which is 90/300 = 30%. Kind of taking the avg. out of it.

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

let total income =100.
so saving of three companies are 20%*100+30%*100+40%*100=90.
so % saving =(90/300)*100
