As per the given above table , we can see
Total production of scooters of all factories = 115 + 108 + 149 + 102 + 101 = 575
Number of given years = 5Required Average = Total production of scooters of all factories Number of given years
Correct Option: A
As per the given above table , we can see
Total production of scooters of all factories = 115 + 108 + 149 + 102 + 101 = 575
Number of given years = 5Required Average = Total production of scooters of all factories Number of given years Required Average = 575 = 115 5
Clearly, it was in the year 1985.

On the basis of given table in question ,
Total population in 1992 = 160998
Total population in 1991 = 153922 – 5337 = 148585
∴ Increase in population in 1992 over 1991 = Total population in 1992 - Total population in 1991Correct Option: B
On the basis of given table in question ,
Total population in 1992 = 160998
Total population in 1991 = 153922 – 5337 = 148585
∴ Increase in population in 1992 over 1991 = Total population in 1992 - Total population in 1991
Increase in population in 1992 over 1991 = 160998 – 148585 = 12413

On the basis of given table in question ,
Total population in 1990 = 153922
Decrease in 1991 = 5337
Total population in 1991 = Total population in 1990 - Decrease in 1991 = 153922 – 5337 = 148585
Total population of men and children in 1991 = 69395 + 21560 = 90955
Number of women in 1991 = Total population in 1991 – total population of men and children in 1991Correct Option: A
