Answer 2

Given :

The age of aryan and arjun are in ratio 5:7

To find :

four year later their ages will be in the ratio 3:4 find their ages

Solution:

Let the ratio of age of aryan and arjun are in ratio 5:7

Aryan's age = 5x

Arjun's age = 7x

Aryan's age after 4 years later = 5x + 4

Arjun's age after 4 years later  = 7x + 4

four year later their ages will be in the ratio 3:4

So, $\frac{5x+4}{7x+4}=\frac{3}{4}$

20x+16=21x+12

4=x

Aryan's age = 5x =5(4)=20

Arjun's age = 7x =7(4)=28

Hence Aryan's age is 20 years and Arjun's age is 28 years
