The line chart given below shows the production of bike and truck by five companies L, M, N, O and P.

Which of the following statement is correct?

I. The ratio of production of bike to the production of truck by company M are 7 : 4.

II. The difference between average of production of bike and truck by all companies is 10.

Both I and II

I. The ratio of production of bike to the production of truck by company M are 7 : 4.

Production of Bike by M :  Production of truck by M

              350                :              200

                7                  :               4

Statement I is  correct .

II. The difference between average of production of bike and truck by all companies is 10.

Average production of Bike = \(\frac{600 + 350 + 400 + 150 + 200 }{5}\)

= \(\frac{ 1700 }{5}\)

= 340

Average production of Truck = \(\frac{400 + 200 + 100 + 500 + 550 }{5}\)

= \(\frac{ 1750 }{5}\)

= 350

Difference = 350 - 340 = 10

Statement II is correct.

Ans :-Both I and II
