Percentage P6 2009 SA2 P2 Rulang Q16

16. Paul earned 20% more money than Ramli. Steve earned 40% less money than Paul. When Steve worked overtime and earned an additional $384, he would have twice as much money as Ramli. How much did the three men earn altogether if Steve had not worked overtime?

R -- > 100%
P -- > 120%
S -- >60% x 120% = 72%

200 – 72 = 128
100 + 120 + 72 = 292

128% -- > $384
1% -- > 384 ÷ 128 = 3

292% à 292 x 3 = $876

The three men earned $876.
