Correct Option: B

On the basis of given graph in question ,
Production of fertilizers in 1995 = 70
Production of fertilizers in 1996 = 80
Production of fertilizers in 1997 = 90
Production of fertilizers in 1998 = 80
Production of fertilizers in 1999 = 60
Production of fertilizers in 2000 = 75
Sum of production of fertilizers in the first three years = 70 + 80 + 90 = 240 lakh tonnes
Sum of production of fertilizers in the last three years = 80 + 60 + 75 = 215 lakh tonnes

Required difference =
1
[(Sum of production of fertilizers in the first three years – Sum of production of fertilizers in the last three years)]
3

Required difference =
1
[(240 – 215)] lakh tonnes
3

Required difference =
25
lakh tonnes
