Answer 2

Problem Analysis

We are given that Vitya bought a book of fairy tales and a book about animals. The fairy tale book costs 200 rubles, which is 4 times more than the cost of the book about animals. We need to find the cost of the book about animals, given that Vitya received 60 rubles in change after the purchase.

Solution

Let's assume the cost of the book about animals is x rubles. According to the problem, the fairy tale book costs 4 times more than the book about animals. So, we can write the equation:

200 = 4x

To find the value of x, we can divide both sides of the equation by 4:

x = 200 / 4 = 50

Therefore, the book about animals costs 50 rubles.

Now, let's check if this answer is consistent with the given information. We are told that Vitya received 60 rubles in change after the purchase. If the book about animals costs 50 rubles, and Vitya paid 200 rubles for the fairy tale book, then the total cost of both books is 200 + 50 = 250 rubles. If Vitya received 60 rubles in change, then the total amount he paid is 250 + 60 = 310 rubles, which matches the given information.

So, the book about animals costs 50 rubles.

Answer

The book about animals costs 50 rubles.
