Study the following table and answer the questions.
Number of machines (in thousands) sold by dealers A, B, C, D and E during six months of 2022.
What is the ratio of machines sold by dealer B in January and average of sale of dealer A over all months?
Answer & explanation
Correct answer: option 3
Sale of machines by dealer B in January = 600
Total sale of A = 620 + 640 + 628 + 635 + 430 + 625 = 3578
Average = \(\frac{3578}{6}\)
Ratio = 600 : \(\frac{3578}{6}\) ⇒ 3600 : 3578 ⇒ 1800 : 1789
