Given:
Average weight of Tushar, Salil, and Mukund = 45 kg
Average weight of Tushar and Salil = 43 kg
Average weight of Salil and Mukund = 44 kg
Formula Used:
Sum of weights = Average × Number of people
Solution:
Sum of weights of Tushar, Salil, and Mukund = 45 × 3 = 135 kg
Sum of weights of Tushar and Salil = 43 × 2 = 86 kg
Sum of weights of Salil and Mukund = 44 × 2 = 88 kg
