Answer 2

Calculating the Mother's Age Relative to Her Children's Ages

To calculate the number of years it will take for the mother's age to equal the sum of her three children's ages, we can use a simple algebraic approach.

Let's denote the mother's age as M, and her three children's ages as A, B, and C. According to the information provided, the current ages of the children are 10, 12, and 15 years old, respectively.

We can set up the following equation to represent the relationship between the mother's age and her children's ages: M = A + B + C

Substituting the given ages of the children into the equation: M = 10 + 12 + 15 M = 37

So, the mother's current age is 37 years old.

Now, we want to find out how many years it will take for the mother's age to equal the sum of her three children's ages.

Let's denote the number of years it will take as x.

The equation to represent this relationship is: M + x = A + x + B + x + C + x

Solving for x: 37 + x = 10 + x + 12 + x + 15 + x 37 + x = 37 + 3x

Subtracting 37 from both sides: x = 3x

Dividing both sides by 3: x = 0

This means that the mother's age will equal the sum of her three children's ages in 0 years, which is not possible. It seems there might be a mistake in the initial question or the information provided.
