Let respective weights of Somdev, Gurdeep and Ritu is s,g,r kg
Average weight of the three =

s+g+r

3

=85
⇒ s+g+r=85×3 =255 kg -------(i)
Similarly, Total weight of Somdev and Gurdeep = s+g=79×2=158 kg ------(ii)
Total weight of Gurdeep and Ritu = g+r=73×2=146 kg -------(iii)
Adding equations(ii) and (iii), ⇒ s+2g+r=158 +146=304 ----(iv)
Subtracting equation (i) from (iv), we get :
⇒ g=304−225=49 kg
