For the total of these four families, what is the difference (in kg) between the average consumption per year of wheat and that of oats?
Answer & explanation
Correct answer: option 3
Average consumption of wheat = \(\frac{162 + 196 + 187 + 189 }{4}\)
= \(\frac{ 734}{4}\) = 183.5
Average consumption of oats = \(\frac{131 + 116 + 103 + 101 }{4}\)
= \(\frac{ 451}{4}\) = 112.75
Difference in Average consumption of wheat & Oats = 183.5 - 112.75 = 70.75
