Answer 1

Answer:

When Rahul's age is 10

And Rahul's father age is 30 more than Rahul's age then

Rahul's father age will be 30 +10= 40

When Rahul's father age will be 72 then Rahul's age will be 72-30

Then Rahul's age will be 42

Then ratio will be 72:42

That is 12:7

Hope u understand

Answer 2

Answer:

12: 7

Step-by-step explanation:

Age of Rahul = 10

Age of Rahul's father = 30 more than rahul = 10 + 30 = 40

When Father's age is 72, then according to the question rahul's father is 30 years older. Therefore,

Rahul's age = 72 - 30 = 42

Ratio of Rahul's father to that of Rahul = 72 : 42 = 12 : 7
