Answer:
Aman's age = 20, Arun's age = 28
Step-by-step explanation:
Let
= Aman's age
Let
= Arun's age
- - - -
(Sum of their age is 56 after 4 years in the future)
![x+y+8=56](https://tex.z-dn.net/?f=x%2By%2B8%3D56)
![x+y=48](https://tex.z-dn.net/?f=x%2By%3D48)
(Ages are in the ratio 5:7)
![x=\frac{5}{7}y](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5%7D%7B7%7Dy)
Now, we can use substitution to find for Arun's age:
![\frac{5}{7}y+y=48](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B7%7Dy%2By%3D48)
![\frac{12}{7}y=48](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B7%7Dy%3D48)
![y=28](https://tex.z-dn.net/?f=y%3D28)
∴ Arun is ![28](https://tex.z-dn.net/?f=28)
To find for Aman's age, we can use substitution:
![x+y=48](https://tex.z-dn.net/?f=x%2By%3D48)
![x+28=48](https://tex.z-dn.net/?f=x%2B28%3D48)
![x=20](https://tex.z-dn.net/?f=x%3D20)
∴ Aman is 20
