Detailed Solution & Logic
Correct Answer:
32
Let the weights of Gopal, Akshay, Atul be G, A, T.
Given: $ \frac{G + A + T}{3} = 46 G + A + T = 138 $
$ \frac{G + A}{2} = 40 G + A = 80 $
$ \frac{A + T}{2} = 45 A + T = 90 $
Add the last two equations: (G + A) + (A + T) = 80 + 90
G + 2A + T = 170
G + A + T = 138
(G + 2A + T) - (G + A + T) = 170 - 138
A = 32
Answer = 32
