Problem Analysis

We are given that a daughter is 10 years old and her mother is 36 years old. We need to determine how many years it will take for the mother to be twice as old as the daughter.

Solution

Let's assume that it will take x years for the mother to be twice as old as the daughter.

Currently, the daughter is 10 years old and the mother is 36 years old. After x years, the daughter will be 10 + x years old and the mother will be 36 + x years old.

According to the problem, the mother will be twice as old as the daughter after x years. Mathematically, we can represent this as:

36 + x = 2 * (10 + x)

To solve this equation, we can simplify it step by step:

1. Distribute the 2 on the right side of the equation: 36 + x = 20 + 2x

2. Subtract x from both sides of the equation: 36 = 20 + x

3. Subtract 20 from both sides of the equation: 16 = x

Therefore, it will take 16 years for the mother to be twice as old as the daughter.

Answer

It will take 16 years for the mother to be twice as old as the daughter.

Verification

Let's verify our answer using the given information. Currently, the daughter is 10 years old and the mother is 36 years old. After 16 years, the daughter will be 10 + 16 = 26 years old and the mother will be 36 + 16 = 52 years old. As we can see, the mother is indeed twice as old as the daughter after 16 years.

Conclusion

In conclusion, the mother will be twice as old as the daughter after 16 years.
