Martha met Ellen in the grocery store alone and asked her age. Martha realized she was twice as old as Ellen will be in six years. If Ellen is 10 years old now, calculate Martha's age now. Think carefully first, then make a decision:
In six years, Ellen will be 10 + 6 = 16 years old. If Martha is twice Ellen's age in six years, she is 2 * 16 = 32 years. So, the answer is 32.
