Study the information below and answer questions based on it. Ten coins are distributed among four people P, Q, R & S such that if one person gets n coins, second gets (n +1), third gets (n + 2) and so on but not necessarily in the same order. Q gets more coins than P and S gets fewer coins than R. If R gets two coins more than S but maximum number of coins which of the following is necessarily true ?
