Answer 1

Hey mate here is your answer:
________________________

Let the age of A be 5x
Let the age of B be 3x

After six years:
age of A will be 5x + 6
age of B will be 3x + 6

According to the question:
5x+6/3x+6=7/5
5(5x+6)=7(3x+6)
25x+30=21x+42
25x-21x=42-30
4x=12
X=12/4
X=3

Sum of their present ages:
age of A = 5x =5(3)=15years
age of B =3x=3(3)=9 years
sum of their present ages =age of A+age of B
=15+9
=24 years
