Answer:
The ratio of ages of two person is 4:7
Let the common multiple be x
Therefore the age of two person will be 4x and 7x
As per the condition given,
7x-4x=30
3x=30
x=10
Substituting the value of x in both the ages,
4x=4×10=40
7x=7×10=70
Therefore sum of both the ages will be
4x+7x=40+70=110
Answer:110
