To find out when they will next both purchase new cars in the same year, we need to find the least common multiple (LCM) of 4 and 6.
The multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, ...
The multiples of 6 are: 6, 12, 18, 24, 30, 36, ...
From the list, we can see that the least common multiple of 4 and 6 is 12.
Therefore, they will next both purchase new cars in the same year after 12 years.
The correct answer is: C. in 12 years.
