    As per the given above table , we can see
    Total production of all types of cars in 1992 = 90
    Total production of all types of cars in 1991 = 75
    Increase in production = 90 - 75 = 15

    Required answer =
    Increase in production
    		 × 100 =%
    Total production of all types of cars in 1991

    Correct Option: B

    As per the given above table , we can see
    Total production of all types of cars in 1992 = 90
    Total production of all types of cars in 1991 = 75
    Increase in production = 90 - 75 = 15

    Required answer =
    Increase in production
    		 × 100 =%
    Total production of all types of cars in 1991

    Required answer =
    15
    		 × 100 = 20%

    According to given table, we can see
    The production of car of S type in 1989 = 4
    The production of car of S type in 1990 = 6
    The production of car of S type in 1991 = 10
    The production of car of S type in 1992 = 16
    The production of car of S type in 1993 = 20
    The production of car of S type in 1994 = 31

    Correct Option: D

    According to given table, we can see
    The production of car of S type in 1989 = 4
    The production of car of S type in 1990 = 6
    The production of car of S type in 1991 = 10
    The production of car of S type in 1992 = 16
    The production of car of S type in 1993 = 20
    The production of car of S type in 1994 = 31
    From visual inspection of table it is clear that the continuous increase in production is obtained from S type of car.

    According to given table, we have
    Total production of cars of all types taken together in given years = 476
    Number of given years = 6

    Average =
    Total production of cars of all types taken together in given years
    Number of given years

    Correct Option: C

    According to given table, we have
    Total production of cars of all types taken together in given years = 476
    Number of given years = 6

    Average =
    Total production of cars of all types taken together in given years
    Number of given years

    Average =
    476
    		= 79.33 ≈ 80
    6

    Which is equal to total production of all types of cars in 1993.
