Use some thinking to answer the following question. The average weight of 36 men is 50 kg. It was found later that the figure of 37 kg was misread as 73 kg. What is the correct average?
Options:
(A) 49 kg
(B) 51 kg
(C) 50.5 kg
(D) 51.5 kg
(E) None of these
Correct average = [( 50 x 36) - 73 + 37 )]/36 = 1764/36 = 49 kg. So the final answer is (A).
