Sum of weights of 25 students is 1275 kg. Out of these 25 students, 24 students are chosen randomly and their average weight comes out to be 50 kg. How much is the weight of one remaining student?
(A) 65 kg
(B) 70 kg
(C) 75 kg
(D) 80 kg
(E) None of the above
Let be the weights of 25 students.
It is given to us that sum of weights of 25 students is 1275 kg.
It is also given to us that average weight of 24 chosen students is 50 g.
Weight of 1 remaining student = Sum of weights of 25 students - sum of weights of 24 students = 1275-1200=75 kg
Hence, the answer is (C).
