Answer 1

4 конфеты-половина от оставшегося. Следовательно,
4+4=8-всего конфет, которые не съели внуки
8+8=16-конфеты, которые съели и внуки, и сама Мария Ефимовна

Answer 2

Problem Analysis

To solve this problem, we need to determine the total number of candies that were originally in the box. We are given the following information: - Maria Efimovna bought a box of candies. - Half of all the candies were eaten by her grandchildren. - Maria Efimovna ate half of the remaining candies. - There were 4 candies left in the box.

Solution

Let's assume that the total number of candies in the box was x.

According to the given information: - The grandchildren ate half of all the candies, which is x/2. - The remaining candies after the grandchildren ate were x/2 - x/4 (half of the remaining candies).

We are also given that there were 4 candies left in the box, so we can set up the following equation:

x/2 - x/4 = 4

To solve this equation, we can multiply both sides by 4 to eliminate the denominators:

2x - x = 16

Simplifying the equation, we get:

x = 16

Therefore, there were originally 16 candies in the box.

Answer

There were originally 16 candies in the box.
