Correct Answer: If the data in either Statement I alone or in Statement II alone are sufficient to answer the question
Explanation:
From Statement I,
Total weight of Arun, Suraj and Vinay = 3 x Average weight = 3 x 68 kg
∴ Arun's weight = 3 x 68 - (78 + 46) = 80 kg
Now, total weight of Raju and Pradeep = 2 x 72 = 144 kg
∴ Pratap's weight = 144 - 68 = 76 kg
∴ Second highest weight = 78 kg
(Suraj's weight)
From statement II,
Total weight of Arun, Suraj, Vinay and Raju = 4 x 68 = 272 kg
∴ Arun's weight = 272 - (78 + 68 + 46)
∴ Arun's weight = 272 - 192 = 80 kg
∴ Second highest weight = 78 kg (Suraj's weight)
