Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 37
Let weights of Gopal, Akshay and Atul be G, A and T
Average of Gopal, Akshay, Atul = 45
G + A + T = 45 × 3 = 135
Average of Gopal and Akshay = 43
G + A = 43 × 2 = 86
Average of Akshay and Atul = 43
A + T = 43 × 2 = 86
T = 135 − 86 = 49
A + 49 = 86 → A = 37
