Math Problem: The sum of the ages of Rebecca and his parents is 82 years old. It is known that his father is 4 years older than his mother, and his mother is 24 years older than Wang Yan. How old are they? Solution: 1 Rebecca's father is four years older than his mother, that is, 24+4 = 28 years older than Wang Yan. 2. Subtract the part where mom and dad are older than Wang Yan from the total age of three people, and the remaining three people are of the same age (which can be understood as the age of three Rebecca). That is 82-28-24 = 30 years old. 3. Divide 30 years old by 3 to get Rebecca's age. 30 ÷ 3 = 10 (years old). 4. Calculate dad's age: 10+28 = 38 (years old). 5. Calculate the mother's age: 10+24 = 34 (years) or 38-4 = 34 (years). 6. Examination: 38+34+ 10 = 82 years old. All the conditions are met and the answer is correct. I hope you are satisfied.
