Answer 3

Let's use algebra to solve the problem. Let's assume Vanya's age is V years and Papa's age is P years.

According to the information given:

1. Grandfather is 7 times older than Vanya: Grandfather's age = 7 * V
2. Vanya is 4 times younger than Papa: Vanya's age = Papa's age / 4

Given that Grandfather's age is 63 years, we can set up two equations:

1. Grandfather's age = 7 * V = 63
2. Vanya's age = Papa's age / 4

Now, let's solve for Vanya's age:

1. 7 * V = 63 V = 63 / 7 V = 9

Now that we know Vanya's age is 9 years, we can find Papa's age:

2. Vanya's age = Papa's age / 4 9 = Papa's age / 4 Papa's age = 9 * 4 Papa's age = 36

So, Vanya is 9 years old, and Papa is 36 years old.
