Всем им, не считая мальчика и деда, 100 лет. Сколько лет мальчику?????????

Answer 1

Ответ:

4 года

Пошаговое объяснение:

6/7*7=6 раз больше маме лет

7/1=7 раз больше папе лет

12/1=12 раз больше бабушке

100/(6+7+12)=4 года мальчик

проверка:

4*365-4*365/7=1251 будних

1251/52=24 года мама

4*365/52=28 лет папа

4*12=48 лет бабушка

24+28+48=100 лет

Answer 2

#### Problem Analysis The problem states that the grandfather was asked how old his grandson is. The grandfather responded with a series of statements: - The grandson has lived as many weekdays as his mother has lived Sundays. - The grandson has lived as many days as his father has lived weeks. - The grandson has lived as many months as his grandmother has lived years. It is also mentioned that the combined ages of the mother, father, and grandmother, excluding the grandson and grandfather, is 100 years. We need to determine the age of the grandson. #### Solution Let's break down the problem and solve it step by step. 1. Let's assume the age of the grandson is **G** years. 2. The number of weekdays the grandson has lived is equal to the number of Sundays the mother has lived. Since there are 7 days in a week, the number of weekdays the grandson has lived is **G * 7**. 3. The number of days the grandson has lived is equal to the number of weeks the father has lived. Since there are 7 days in a week, the number of days the grandson has lived is **G * 7**. 4. The number of months the grandson has lived is equal to the number of years the grandmother has lived. The number of months in a year is 12, so the number of months the grandson has lived is **G * 12**. 5. The combined ages of the mother, father, and grandmother, excluding the grandson and grandfather, is 100 years. So, we can write the equation: **(M + F + B) = 100**, where **M** is the age of the mother, **F** is the age of the father, and **B** is the age of the grandmother. 6. We can substitute the values from steps 2, 3, and 4 into the equation from step 5: **(G * 7 + G * 7 + G * 12) = 100**. 7. Simplifying the equation: **26G = 100**. 8. Solving for **G**: **G = 100 / 26**. 9. Evaluating the expression: **G ≈ 3.846**. Therefore, the approximate age of the grandson is **3.846 years**. Please note that the age of the grandson is an approximation, as the problem does not provide exact values for the ages of the mother, father, and grandmother.
