Francesca, Georgina, Harold, Ivan, and Justice recently discovered that all of their birthdays were on the same day. However, none of them are the same age. They threw a party to celebrate their birthdays and I happened to overhear some of their conversation: ❏ Ivan said to Georgina: "I'm nine years older than Justice."
❏ Justice said to Georgina: "I'm seven years older than Francesca."
❏ Francesca said to Georgina: "Your age is exactly 70% greater than mine."
❏ Georgina said to Harold: "Justice is younger than you."
❏ Harold said to Ivan: "The difference between our ages is six years."
❏ Harold said to Francesca: "I'm ten years older than you."
❏ Harold said to Francesca: "Georgina is younger than Ivan."
❏ Georgina said to Harold: "The difference between your age and Ivan's is the same as
the difference between Ivan's and Justice's."
I noticed some of them were not telling the truth. I realized that when one of them spoke to someone who was older than them, they told the truth, but when speaking to someone younger than them, they lied.
