The ratio of the ages of two persons are in the ratio of 5:7 and the d...
Given:
Ratio of ages of two persons = 5:7
Difference in their ages = 18 years

Let the ages of the two persons be 5x and 7x.

Then, (7x - 5x) = 18
=> 2x = 18
=> x = 9

So, the ages of the two persons are 45 and 63 years.

After 5 years, their ages will be 50 and 68 years.

Therefore, the sum of their ages after 5 years = 50 + 68 = 118 years.

Hence, the correct answer is option E, None of these.
