Problem Analysis

We are given the information that Vasiliy and Petya together have 60 rubles. If Vasiliy gives Petya 5 rubles, he will have twice as much money left as Petya. We need to determine how much money Vasiliy has.

Solution

Let's assume that Vasiliy has x rubles. According to the given information, Petya will have (60 - x) rubles.

If Vasiliy gives Petya 5 rubles, he will have (x - 5) rubles left. This amount will be twice as much as Petya's money, so we can write the equation:

(x - 5) = 2 * (60 - x)

Now, let's solve this equation to find the value of x.

Equation Solving

Expanding the equation:

x - 5 = 120 - 2x

Combining like terms:

3x = 125

Dividing both sides by 3:

x = 41.67

Since we are dealing with money, we can round this to the nearest ruble. Therefore, Vasiliy has approximately 42 rubles.

Conclusion

Based on the given information, Vasiliy has approximately 42 rubles.
