Explanation

Let the younger brother's present age = x years

Then older brother's present age = x + 9 years

After 5 years:

Younger brother's age = x + 5

Older brother's age = x + 9 + 5 = x + 14

Sum after 5 years = 49

So, (x + 5) + (x + 14) = 49  

2x + 19 = 49  

2x = 49 - 19  

2x = 30  

x = 15

Younger brother = 15 years  

Older brother = x + 9 = 15 + 9 = 24 years

Explanation

Let the son's age = x years

Mother's age = 5 times son's age = 5x years

Sum of their ages = 60 years

So, x + 5x = 60

6x = 60  

x = 60 / 6  

x = 10

Son's present age = 10 years
