Amsa: 12 <eng> For this chain-of-thought reasoning and answer, what was the question?
He spent 2 * 2 = 4 years learning to climb. He spends 5 * 7 = 35 months climbing all 7 mountains. After a 13 month break, he starts diving so that is 35 + 13 = 48 months. That means it is 48 / 12 = 4 years. So in total it all took 2 + 4 + 4 + 2 = 12 years.
