The ages of Aman and Arun are in the ratio 5:7. Four years later the sum of their ages will be 56 years. What are their present
Viktor [21]

Answer:

Aman's age = 20, Arun's age = 28

Step-by-step explanation:

Let x = Aman's age

Let y = Arun's age

- - - -

x+4+y+4=56 (Sum of their age is 56 after 4 years in the future)

x+y+8=56

x+y=48

\frac{x}{y} = \frac{5}{7} (Ages are in the ratio 5:7)

x=\frac{5}{7}y

Now, we can use substitution to find for Arun's age:

x+y=48

\frac{5}{7}y+y=48

\frac{12}{7}y=48

y=28

∴ Arun is 28

To find for Aman's age, we can use substitution:

x+y=48

x+28=48

x=20

∴ Aman is 20

Hope this helps :)
