Direction: The bar graph provided below gives the data of the production of paper (in lakh tonnes) by three different companies X, Y and Z over the years. Study the bar chart and answer the following questions.

  1. The ration of the average production of company X in the period 1998-2000 to the average production of company Y in the same period is :
    1. 27 : 29
    2. 23 : 25
    3. 25 : 26
    4. 24 : 27
Correct Option: B

As per the given bar graph , we have
Total production of company X during 1998 – 2000 = 25 + 50 + 40 = 115 lakh tonnes
Number of given years = 3

Average production of company X ⇒ Total production of company Xlakh tonnes
Number of given years

Average production of company X =
115
lakh tonnes
3

Total production of company Y during 1998 – 2000 = 35 + 40 + 50 = 125 lakh tonnes
Number of given years = 3
Average production of company Y ⇒ Total production of company Ylakh tonnes
Number of given years

Average production of company Y ⇒ 125lakh tonnes
3

Required ratio =
115
:
125
= 23 : 25
