Age Problems( Week 30 Practice) 1. The average age of 7 people is 25. None of them are younger than 14 years old. How old is the oldest possible age in the group? 2. David's age is a multiple of 5 this year. Next year it will be a multiple of 4. At least how old is he now? 3. Niconia's age is of Ben's age this year. 2 years ago, her age was of Ben's age. How old is Niconia now? 4. The sum of the ages of three brothers is 6. The oldest brother is 3 times as old as the youngest one. The ages of the two younger brothers differ by 1 year. What is the age of the brother in the middle? 5. Two people have the same two digits for their ages but their ages are in reverse order with each other (i.e. if one is 19 years old, then the other is 91 years old). If the sum of the two digits is 7, and one person is 9 years older than the other, how old is the older person? |
