Answer 1

Correct Answer - Option 4 : 75.5

According to the given information :

Production of mobile phones in 2012 = 57 + 79 + 74 + 92 = 302.

Number of models = 4 (A, B, C, D)

Average = (Total Production) / (Number of Models)

Average production = 302 / 4 = 75.5.

Hence, the correct answer is "75.5".
