1) mn − pq = 12
(2) p + q = 21.
Try to plug in values that satisfy all the conditions given.
Let (m,n) = (100, 12/100) and (p,q) = (0,21).
Is (m,n) farther? Yes.
Let (m,n) = (3,4) and (p,q) = (0,21).
Is (m,n) farther? No.
Since the combinations above satisfy both statements, and in the first case the answer is Yes and in the second case the answer is No, the correct answer is
