Answer 2

Answer:

3:1 or 1:3

Step-by-step explanation:

Let the age of Mr. Ravi's son be x

Then, age of Mr. Ravi will be 4x

A.T.Q- x + 4x = 40

5x = 40

x= 8

Age of Mr. Ravi's son is 8 years.

Therefore, Age of Mr. Ravi is 32 years.

Age of Mr. Ravi's son after 4 years = 12 years.

Age of Mr. Ravi after 4 years = 36 years.

Hence, Ratio of their ages =

$\frac{age \: of \: mr. \: ravi}{age \: of \: mr. \: ravis \: son} \\ \\ \frac{36}{12}$

3:1 or 1:3
