(Alice, Benny và Celine góp chung một số tiền là Benny $ 590. Alice có nhiều hơn Benny 20% và Celine ít hơn Benny 25%. Alice có bao nhiêu tiền so với Celine?)


Let the amount of money shared by Alice, Benny and Celine be x, y and z respectively.
Sum of money with the three of them, x + y + z = 590.
Alice has 20% more than Benny so we have: x = 120% y = 1,2 y
Celine has 25% less than Benny : y = 125% z = 1,25 z
We get , x = 1,2 y = 1,2 . 1,25 z = 1,5 z = 150% z
Then Alice has 50% more than Celine
