Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 34 .
Average weight of Tushar, Salil, Mukund = 46 kg
Total weight = 46 × 3 = 138 kg
Tushar + Salil = 40 × 2 = 80 kg
Salil + Mukund = 46 × 2 = 92 kg
T + 2S + M = 80 + 92 = 172 kg
T + M + S = 138
(T + 2S + M) − (T + S + M) = 172 − 138
S = 34 kg
