Alice’s mother is now four times as old as she. Four years ago, her mother was thirty years more than her. How old is Alice now?
my mother is 24 years old and 6 time as old I was many years ago. now she is three times as old as I am. how old is she now
When my mother was 24 years old, I was: 24:6=4 (years old)
==> The difference between my mother's age and my age that time was: 24 - 4 = 20 (years old)
Because the difference between my mother's age and my age never changes, so now, she is 20 years older than me.
We have a diagram: Bạn vẽ sơ đồ tuổi con hiện nay (My age now) với 1 phần, tuổi mẹ hiện nay (My mother's age now) với 3 phần bằng nhau như thế. (tự vẽ nha)
==> My mother's age now is: [20: (3-1)] * 3 = 30 (years old)
