The ratio of Mrs Lee's age to her son's age now is 4 : 1
5 years later, the ratio of Mrs Lee's age to her son's age will become 3 : 1
How old is Mrs Lee now?
Answer: Let Mrs Lee's age and her son's age now be 4x and x respectively.
Mrs Lee's age after 5 years = 4x + 5
Her son's age after years = x + 5
We know that the ratio of Mrs Lee's age to her son's age after 5 years will be 3:1. Therefore, we have:
We have son's current age = 10 years
Therefore, Mrs Lee's is years old now
