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
