Question

До обеда дедушка сорвал с дерева 25 груш,а после обеда 17 груш. После этого на дереве осталось на 26 груш меньше, чем сорвал дедушка. Сколько груш осталось на дереве? Сколько груш было на дереве первоначально?

Answer 1

1)25+17=42груши-сорвал.
2)42-26=16груш-осталось.
3)42+16=58груш-было сначало.

Answer 2

25+17=42 (сорвал дедушка за весь день)
42-26=16 (груш осталось)
42+16=58 (груш было на дереве изначально)

Answer 3

Problem Analysis

To solve this problem, we need to determine the number of pears that were initially on the tree and the number of pears that remained on the tree after the grandfather picked some. We are given that the grandfather picked 25 pears before lunch and 17 pears after lunch. We also know that after picking, there were 26 fewer pears on the tree than the number the grandfather picked.

Solution

Let's assume that the initial number of pears on the tree is x.

1. Before lunch, the grandfather picked 25 pears, so the number of pears remaining on the tree is x - 25. 2. After lunch, the grandfather picked 17 pears, so the number of pears remaining on the tree is (x - 25) - 17. 3. We are also given that the number of pears remaining on the tree is 26 fewer than the number the grandfather picked, so we can set up the equation: (x - 25) - 17 = x - 26.

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

(x - 25) - 17 = x - 26

Simplifying the equation:

x - 25 - 17 = x - 26

x - 42 = x - 26

Subtracting x from both sides:

-42 = -26

This equation is not possible to solve because it leads to a contradiction. It means that there is no valid solution for the initial number of pears on the tree.

Therefore, we cannot determine the number of pears that remained on the tree or the number of pears that were initially on the tree based on the given information.
