If the average (arithmetic mean) of the four numbers K, 2K + 2, 3K – 5 and 5K + 1 is 63, what is the value of K?\nOptions:\n(A)  11\n(B)  15 3/4\n(C)  22\n(D)  23\n(E)  23 1/11 Stream of consciousness first, then make a decision:
User
K + 2K +2 + 3K - 5 + 5K +1 = 11K -2\n(11K -2)/4 = 63\n11K = 63 * 4 +2 = 252 +2 = 254\nK = 254 / 11 = 23 1/11
Thus, the answer is (E).
