Problem

Two farmers agree that pigs are worth $300$ and that goats are worth $210$. When one farmer owes the other money, he pays the debt in pigs or goats, with "change" received in the form of goats or pigs as necessary. (For example, a $390$ debt could be paid with two pigs, with one goat received in change.) What is the amount of the smallest positive debt that can be resolved in this way?

$\mathrm{(A) \ } $5\qquad \mathrm{(B) \ } $10\qquad \mathrm{(C) \ } $30\qquad \mathrm{(D) \ } $90$ (Error compiling LaTeX. Unknown error_msg)$\mathrm{(E) \ } $210$ (Error compiling LaTeX. Unknown error_msg)
