Their Present ages :-

Person A = 4x = 40

Person B = 3x = 30

Step-by-step explanation:

Given:-

Ratio of Ages = 4 : 3

Will keep their ages as 4x and 3x.

Five years hence

= 4x + 5 : 3x + 5 = 9 : 7

= 4x + 5/3x + 5 = 9/7

= 7 (4x + 5) = 9 (3x + 5)

= 28x + 35 = 27x + 45

= x = 10

Their Present ages :-

Person A = 4x = 40

Person B = 3x = 30

Answer:

Their present ages of A & B are 40 years & 30 years respectively

Step-by-step explanation:

Let 4x, 3x be the ages Of A & B respectively

Now

5 years hence their ages will change to 4x+5 & 3x+5 respectively

By the given condition

(4x+5):(3x+5) = 9:7

So

(4x+5)/(3x+5) = 9/7

28x+35 = 27x+45

x = 10

So

Their present ages of A & B are 40 years & 30 years respectively
