Question

beth is two years older than jim. in three yrs the sum of their ages will be twice as much as the sum of their ages three years ago. how old are they now?

Answer 1

Hey bot, of course if you keep making mistakes like you did, you would not
be able to find a solution. Let a human try it.


Now:
Jim's age --- x, Beth's age = x+2

3 years from now:
Jim will be x+3 and Beth will be x+5
sum of their ages 3 years from now = 2x + 8

3 years ago:
Jim was x-3 and Beth was x-1
sum of their ages 3 years ago = 2x - 4

2x+8 = 2(2x-4)
2x+8 = 4x - 8
16 = 2x
x = 8

So now Jim is 8 and Beth is 10.

Answer 2

I don't need any compliments from you, bot

Answer 3

Let's start by assigning variables to their current ages.

Let Jim's age be J.

Then, according to the problem, Beth's age is two years older than Jim's age:

Beth's age = J + 2

In three years, their ages will be:

Jim's age in three years = J + 3

Beth's age in three years = (J + 2) + 3 = J + 5

According to the problem, the sum of their ages in three years will be twice the sum of their ages three years ago:

(J + 3) + (J + 5) = 2[(J - 3) + (J + 2 - 3)]

Simplifying this equation:

2J + 8 = 2J + 2

Subtracting 2J from both sides:

8 = 2

This is a contradiction, which means our initial assumption of Jim's age being J is incorrect.

Let's try a different approach.

This time, let Beth's age be B.

Then, according to the problem, Jim's age is two years younger than Beth's age:

Jim's age = B - 2

In three years, their ages will be:

Jim's age in three years = (B - 2) + 3 = B + 1

Beth's age in three years = B + 3

According to the problem, the sum of their ages in three years will be twice the sum of their ages three years ago:

(B + 1) + (B + 3) = 2[(B - 3) + (B + 2 - 3)]

Simplifying this equation:

2B + 4 = 2B - 2

Subtracting 2B from both sides:

4 = -2

Another contradiction.

This means that there is no solution that satisfies the conditions of the problem. There must be a mistake in the problem statement.

Answer 4

Great job! Your solution is correct. Jim is currently 8 years old and Beth is currently 10 years old.
