The bar graph given below  shows the sales of two companies C1 and C2 in 5 years.

J1 = The average sale of company C1 in year Y1. Y2 and Y3.

J2 = The difference between total sale of company C1 and C2 in all the 5 years.

What is the value of (J2/J1)?

2

J1 = The average sale of company C1 in year Y1. Y2 and Y3

= \(\frac{200 + 400 + 600}{3}\) = 400

J2 = The difference between total sale of company C1 and C2 in all the 5 years

= (200+400+600+500+300) - (1000+700+800 +200 +100)

= 2000 - 2800

= - 800

= 800   ( Difference is always positive )

Now , \(\frac{J2}{J1}\) = \(\frac{800}{400}\) = 2
