Solution

## The correct option is D 9Let's look at the hints. Noah was seven three years ago, this means: 7 + 3 = 10 Noah's age is 10. John's age is not an odd number. This means that his age can be 10, 12, or 14. His age cannot be 10 because Noah is 10 years old. Oliver is 12 of Liam's age. Here, only 7 is the number whose double is also present. Hence, Oliver is 7 years old, and Liam is 14 years old. Now that two even numbers are taken, Noah is 10, and Liam is 14 years old. We can deduce that John is 12 years old. Oliver and Max are two years apart. Oliver is 7 years old. 7 + 2 = 9 Hence, Max is 9 years old.
