Anna is 5 years old.
her mother is 33years old.
In how many years' time will her mother's age be 5 times her age?
The age of the mother over Anna is:
33 - 5 = 28 ( year old)
Anna's age when her mother is 5 times older is:
28:(5-1) = 7 (year old)
The number of years that the mother is 5 times older than Anna is:
7 - 5 = 2(year)
The difference in ages of mother and daughter is:
33 - 5 = 28 (age )
Mother's age is 5 times more than her son's age => Mother's age = \(\frac{5}{4}\) Age difference.
Mother's age at that time was:
28 x = 35 (age )
Then and now:
35 - 33 = 2 (years)

Bài 1: Joel 8 tuổi. Mẹ của cậu 34 tuổi. Hỏi trong bao nhiêu năm nữa, tuổi của của mẹ cậu gấp ba lần tuổi của Joel?
Giải:
Gọi số năm là x => tuổi của mẹ trong x năm là 34 + x; tuổi của Joel trong x năm là 8 + x.
Mà trong x năm tuổi mẹ gấp 3 lần tuổi Joel
=> 34 + x = 3 * (8 + x)
<=> x = 5
Vậy đáp án là 5 năm.
