Question: Eddie is 92 years old. His granddaughter Becky is currently four times younger than he is. The mother of Becky - Irene, is two times her age. How old is Irene? Is final answer 47?
Answer: Becky is four times younger than Eddie, which means she is 92 / 4 = <<92/4=23>>23 years old.
Her mother is two times older than she, so it means Irene is 23 * 2 = <<23*2=46>>46 years old.
