Four friends-Chloe, Evelyn, Francesca, and Grace-went out for lunch. Someone asked them about their ages, and this is what they said: "Evelyn is three times older than Francesca. But three years ago, Francesca was a year younger than Chloe is now. And Grace is two times older than Francesca,". Can you rank the girls in order of their ages?
Think about the relationships between the girls' ages in terms of simple equations, and try to find a common link between them. Focus on Francesca's age, as it seems to be the central piece of the puzzle.
From oldest to youngest, the order is as follows: Evelyn, Grace, Francesca, and Chloe. Evelyn is three times older than Francesca, and Grace is two times older than Francesca. Evelyn is older than Grace because multiplying a number by three will result in a greater number than multiplying the number by two. Both of them are older than Francesca, but if it was three years ago that Francesca was a year younger than Chloe is now, then Francesca is two years older than Chloe. Therefore, Evelyn is the oldest, followed by Grace, then Francesca, and then Chloe.
