Answer 2

Task: Calculate the number of boys standing to the left of Vasya.

To solve this problem, let's break down the information given step by step:

1. There are ten boys standing in a row. 2. Eight boys are standing to the right of Petya. 3. Five boys are standing between Petya and Vasya.

To find the number of boys standing to the left of Vasya, we need to subtract the number of boys standing to the right of Petya from the total number of boys and then subtract the five boys standing between Petya and Vasya.

Let's calculate it:

Total number of boys = 10 Number of boys to the right of Petya = 8 Number of boys between Petya and Vasya = 5

Number of boys to the left of Vasya = Total number of boys - Number of boys to the right of Petya - Number of boys between Petya and Vasya

Number of boys to the left of Vasya = 10 - 8 - 5 = 2

Therefore, there are 2 boys standing to the left of Vasya.
