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:
![\frac{4x+5}{x+5} =\frac{3}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B4x%2B5%7D%7Bx%2B5%7D%20%3D%5Cfrac%7B3%7D%7B1%7D)
![4x +5 =3x +15](https://tex.z-dn.net/?f=4x%20%2B5%20%3D3x%20%2B15%20)
![4x -3x = 15-5](https://tex.z-dn.net/?f=4x%20-3x%20%3D%2015-5)
![x=10](https://tex.z-dn.net/?f=x%3D10)
We have son's current age = 10 years
Therefore, Mrs Lee's is
years old now
Local Calls = 36
Distance calls = 20
Ratio would be: = 36/20 = 18/10 = 9/5
In short, Your Answer would be Option A
Hope this helps!
