    E None of these Correct Answer Incorrect Answer

    Solution

    According to the question, Average weight of Shikhar, Rohit and Virat = 72 kg Total weight of Shikhar + Rohit + Virat = 72 × 3 = 216 kg . Total weight of Shikhar + Rohit + Virat + Hardik = 65 × 4 = 260 kg -------(i) Weight of Hardik = 260 – 216 = 44 kg Weight of Dhoni = 44 + 8 = 52 kg Average weight of Rohit, Virat, Hardik and Dhoni = 53kg Total weight of Rohit + Virat + Hardik + Dhoni = 53 × 4 = 212 kg .................
