Question 942763
Let x be the daughter's present age
The Son's present age is (x + 3)
In one year the man will be 6x
In 10 years the man will be (x + 10) (x + 13) + 14
From this we can say the man's present age is 6x-1
And also in 10 years the man will be 6x +  9
So:::(x + 10) (x + 13) + 14=6x + 9
4x=28
x=7
The man's present age = 6x-1
=6(7)-1
=41
