Detailed Solution
Download Solution PDFGiven:
The average weight of Mahesh, Ram, and Anwar = 46 kg
The average weight of Mahesh and Ram = 39 kg
The average weight of Ram and Anwar = 49 kg
Formula used:
Average = Sum of weights / Number of people
Total weight = Average × Number of people
Calculation:
Sum of Mahesh, Ram, and Anwar = 46 × 3 = 138 kg
Sum of Mahesh and Ram = 39 × 2 = 78 kg
Sum of Ram and Anwar = 49 × 2 = 98 kg
To find Ram's weight:
Sum of all three (138) = Sum of Mahesh and Ram (78) + Anwar's weight
⇒ Anwar's weight = 138 - 78
⇒ Anwar's weight = 60 kg
Sum of Ram and Anwar (98) = Ram's weight + Anwar's weight (60)
⇒ Ram's weight = 98 - 60
⇒ Ram's weight = 38 kg
∴ The correct answer is option (3).
