Question: Lavinia’s daughter is 10 years younger than Katie’s daughter. Lavinia’s son is 2 times the age of Katie’s daughter. If Katie’s daughter is 12 years old, how many years older is Lavinia’s son than Lavinia’s daughter? Is final answer 21?
Answer: Lavinia’s daughter is 12 - 10 = <<12-10=2>>2 years old
Lavinia’s son is 12 * 2 = <<12*2=24>>24 years old
Lavinia’s son is 24 - 2 = <<24-2=22>>22 years older than Lavinia’s daughter.
