Let respective weights of Shivshankar, Gopesh and Reena is s,g,r kg
Average weight of the three =

s+g+r

3

=97
⇒ s+g+r=97×3 = 291 kg ------(i)
Similarly, Total weight of Shivshankar and Gopesh = s+g=93×2= 186 kg ------(ii)
Total weight of Gopesh and Reena = g+r=82×2= 164 kg -------(iii)
Adding equations(ii) and (iii), ⇒ s+2g+r = 186 + 164 = 350 ------(iv)
Subtracting equation (i) from (iv), we get :
⇒ g=350−291=59 kg
