Given :-
- Present age of a and b are in the ratio of 7:5
- 10 years later their age will be in the ratio of 9:7
To find :-
- present ages of a and b
Solution:-
let their ages be 7x and 5x
=
7(7x+10) = 9(5x+10)
49x+70 = 45x + 90
4x = 20
X = = 5x.
hence, their ages are:-
- age of a :- 7(5) = 35years.
- age of b :- 5(5) = 25years.
