My question is: Djibo is 17 years old. Five years ago Djibo added his age with his sister's age and the sum was 35. How many years old is Djibo's sister today? Your thoughts:
Age 5 years ago: 17 - 5 = 12. Sister's age 5 years ago: 35 - 12 = 23. Sister's age today: 23 + 5 = 28 years. Djibo's sister is 28 years old today. The final answer: 28.
