Question 255995
 Let the age of the son = x
Then the age of the daughter = x+5
Given,A father is 6 times as old as his son and 3 times as old as his daughter.
           6x = 3(x+5)
           6x = 3x+15
        6x-3x = 15
           3x = 15
            x = 15/3
            x = 5
Therefore,the age of the son = 5 years
The age of the daughter = x+5 = 5+5 = 10 years
the age of the son = x
The age of the father = 6x = 6*5 = 30 years
