For this chain-of-thought reasoning and answer, what was the question?
The age of Jeremy three years from now will be 40 + 3 = 43 years. Since Sebastian age is four years more than Jeremy's, Sebastian is currently 40 + 4 = 44 years. In three years, Sebastian will be 44 + 3 = 47 years old. The total age of Jeremy and Sebastian in three years will be 47 + 43 = 90. If the total age of Jeremy, Sebastian and Sophia in three years is 150, then Sophia's age in three years will be 150 - 90 = 60.
A: 60
Q: The sum of the ages of Jeremy, Sebastian and Sophia in three years is 150. Currently, Sebastian is 4 years older than Jeremy. If Jeremy's age is 40, calculate Sophia's age three years from now?
