The average weight of three friends Ram, Ramesh, and Shyam is 76 kg. Somesh joins them, and the average weight of the four friends becomes 74 kg. If Mohan, whose weight is 2 kg more than that of Somesh, replaces Ramesh, the average weight of Ram, Shyam, Somesh, and Mohan becomes 68 kg. Find the weight of Ramesh.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 94 kg.
Ram + Ramesh + Shyam = 76 × 3 = 228 kg
Ram + Ramesh + Shyam + Somesh = 74 × 4 = 296
Somesh = 296 – 228 = 68 kg
Mohan = 68 + 2 = 70 kg
Ram + Shyam + Somesh + Mohan = 68 × 4 = 272
Ram + Shyam + 68 + 70 = 272
Ram + Shyam = 272 – 138 = 134 kg
Ramesh = 228 – 134 = 94 kg
