conversations.value: Find the answer to this math problem: Ali turned 8 years old this year, and is now 3 years older than Yusaf. If Umar is twice Yusaf’s age, how old is Umar?

conversations.value: If Ali is 3 years older, then Yusaf must be 8 – 3 = 5 years old.
  Umar is twice Yusaf’s age, so he must be 5 * 2 = 10 years old.
