Solution:

Let 7n and 3n be the number of tokens Narcisse and Aristide respectively had originally and x be the number of tokens Narcisse gave to Aristide. We can create the equation:

(7n - x) / (3n + x) = 6/5

6(3n + x) = 5(7n - x)

18n + 6x = 35n - 5x

11x = 17n

x = 17n/11

Since 17 is not divisible by 11, we see that the least positive value of n is 11. Therefore, the least positive value of x is 17(11)/11 = 17.

Answer: B
