2000 for RF and IT and EF per month...
30% goes to retirement.....0.30(2000) = 600
IT is 80% of RF.....0.80(600) = 480
remainder goes to EF.......2000 - (600 + 480) = 920
which represents 20% of his salary...
920 = 20% of salary (s)
920 = 0.20s
920/0.20 = s
4600 = s.........he earns 4600 per month <==
