Explanation:

Let daily wages of C = X
Then, daily wages of A = 2X
and daily wages of B = X + 40
Hence, average daily wages of A, B and C
= (X + 2X + X + 40) / 3 = (4X + 40)/3
Thus, (4X + 40)/3 =120

=>4X + 40 = 360
=>4X = 320, X = 80.
Therefore, Wages of A per day = 2 x 80 = Rs 160.

Hence, option 3 is the correct answer.
