According to given bar graph in question ,
Sum of the production of fertilizers all six years = 70 + 80 + 90 + 80 + 60 + 75 = 455 lakh tonnes
Total number of years = 6In year 2000 average production of fertilizers = 455 = 75 5 lakh tonnes 6 6 Correct Option: D

On the basis of given graph in question , we have
The total production of fertilizers in the year 1998 and 2000 = ( 90 + 60 ) = 150
The total production in the years 1997 and 1999 = ( 80 + 75 ) = 155The total production of fertilizers in the year 1998 and 2000 × X = The total production in the years 1997 and 1999 100 ⇒ 150 × X = 155 100 ⇒ X = 155 × 100 = 310 150 3
Correct Option: A

As per the given bar graph in question ,
Total production of fertilizers in the year 1995, 1997 and 1999 = 70 + 90 + 60 = 220
Total production of fertilizers in the year 1996, 1998 and 2000 = 80 + 80 + 75 = 235
Required ratio = Total production of fertilizers in the year 1995, 1997 and 1999 : Total production of fertilizers in the year 1996, 1998 and 2000Correct Option: C
