The average of 11 results is 50, if the average of first six results is 49 and that of the last six is 52. Find the sixth result?\nOptions:\n(A) 22\n(B) 56\n(C) 88\n(D) 66\n(E) 21
Step-by-step reasoning:
(B)
1 to 11 = 11 * 50 = 550\n1 to 6 = 6 * 49 = 294\n6 to 11 = 6 * 52 = 312\n6th = 294 + 312 – 550 = 56'.

Thus, the answer is (B)
