Solution:-
Let the age of Aryan and Arjun be 5x and 7x respectively.
Four Years Later,
Age of Aryan = 5x + 4
Age of Arjun = 7x + 4
A.T.Q.
=) [ (5x + 4)/(7x +4) ] = 3/4
=) 4 ( 5x + 4) = 3 ( 7x + 4)
=) 20x + 16 = 21x + 12
=)21x - 20x = 16 - 12
=) x = 4
Hence,
Aryan's Age = 5x = 20 years.
Arjun's Age = 7x = 28 years.

Aryan's age = 5x
Arjun 's age = 7x
4 years later,
5x+4
7x+4
according to the question..
5x+4 : 7x+4 = 3:4
5×45x+4/7x+4 = 3/4
4(5x+4) = 3(7x+4)
20x+16= 21x+12
16-12=21x-20x
4=x
Aryan's age = 5×4=20 years
Arjun s age = 7×4 =28 years
Hope it helps you ...
