Given :-
The present ages of Veeru and Neeru are in the ratio 3:4. Five years from now, the ratio of their ages will be 4:5.
To Find :-
Present ages
Solution :-
Let the ratio of present ages of Veeru and Neeru be 3a and 4a
Given, After 5 years ratio becomes 4:5
3a + 5/4a + 5 = 4:5
3a + 5/4a + 5 = 4/5
5(3a + 5) = 4(4a + 5)
(5 × 3a) + (5 × 5) = (4 × 4a) + (4 × 5)
15a + 25 = 16a + 20
15a - 16a = 20 - 25
-a = -5
a = 5
Hence
Age of Veeru = 3a = 15 years
Age of Neeru = 4a = 20 years
