The bar graph given below shows the sales of bikes and cars of five companies.
P1 = The difference between the average sales of bikes and average sales of cars of all 5 companies.
P2 = The total value of the sales of bikes and cars of all 5 companies. What is the value of (P2 - P1)?
Answer & explanation
Correct answer: option 4
P1 = The difference between the average sales of bikes and average sales of cars of all 5 companies.
Average sale of Bikes = \(\frac{400 + 350 + 550 + 600 + 700}{5}\)
= \(\frac{ 2600}{5}\)
= 520
Average sale of Cars = \(\frac{900 + 450 + 650 + 800 + 700}{5}\)
= \(\frac{3500}{5}\)
= 700
P1 = 700 - 520 = 180
P2 = The total value of the sales of bikes and cars of all 5 companies
= 2600 + 3500
= 6100
Now , ( P2 - P1 ) = 6100 - 180
= 5920
