Average = Sum of weights ∕ Number of people Total weight = Average × Number of people Calculation: Sum of Mahesh, Ram, and Anwar =46×3=138kg Sum of Mahesh and Ram =39×2=78kg Sum of Ram and Anwar =49×2=98kg 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 =60kg Sum of Ram and Anwar (98) = Ram's weight + Anwar's weight (60) ⇒ Ram's weight = 98-60 ⇒ Ram's weight =38kg
