Direction: The following graph shows production (in thousands) of two types (P and Q) of vehicles by a factory over the years 2009 to 2014. Study the graph and answer the given questions.

  1. In how many of the given years, was the production of Type P vehicles of the company more than the average production of this type vehicles in the given years?

    On the basis of given graph in question ,
    Sum of production of type P vehicles = 100 + 125 + 200 + 225 + 275 + 275
    Total number of given years = 6

    Average production of type P vehicles =
    Sum of production of type P vehicles
    Total number of given years

    Average production of type P vehicles =
    100 + 125 + 200 + 225 + 275 + 275
    6

    Correct Option: A

    On the basis of given graph in question ,
    Sum of production of type P vehicles = 100 + 125 + 200 + 225 + 275 + 275
    Total number of given years = 6

    Average production of type P vehicles =
    Sum of production of type P vehicles
    Total number of given years

    Average production of type P vehicles =
    100 + 125 + 200 + 225 + 275 + 275
    6

    Average production of type P vehicles =
    1200
    		 = 200 thousands
    6

    The production of Type P vehicles of the company more than the average production of this type vehicles is 200 thousands .
    So , Required years ⇒ 2012, 2013 and 2014
    Hence , required answer is 3 .

Direction: In the following questions, the Graph shows the demand and production of different companies. Study the graph and answer the questions.

  1. What is the ratio of the companies having more demand than production to those having more production than demand?








  1. View Hint View Answer Discuss in Forum

    As per the given line graph in question , we can see
    Companies having more demand than production ⇒ A and D = 2
    Companies having more production than demand ⇒ B, C, E and F = 4
    ∴ Required ratio = Companies having more demand than production : Companies having more production than demand

    Correct Option: B

    As per the given line graph in question , we can see
    Companies having more demand than production ⇒ A and D = 2
    Companies having more production than demand ⇒ B, C, E and F = 4
    ∴ Required ratio = Companies having more demand than production : Companies having more production than demand
    ∴ Required ratio = 2 : 4 = 1 : 2

  1. The production of company A is approximately what per cent of the demand of company C ?








  1. View Hint View Answer Discuss in Forum

    On the basis of given graph in question , we have
    The production of company A = 1450
    The demand of company C = 2600

    Required percent =
    The production of company A
    		 × 100
    The demand of company C

    Required percent =
    1450
    		 × 100
    2600

    Correct Option: D

    On the basis of given graph in question , we have
    The production of company A = 1450
    The demand of company C = 2600

    Required percent =
    The production of company A
    		 × 100
    The demand of company C

    Required percent =
    1450
    		 × 100
    2600

    Required percent =
    1450
    		 = 55.8
    26

  1. What is the difference between the average demand and the average production of the companies (in lakh tonnes)? [Approximately]

    According to given graph in question ,
    Sum of demand of the all given companies = 2100 + 3150+ 2600+ 5000+ 2800+ 3300
    Total number of companies = 6
    And Sum of production of the all given companies = 1450+ 3660+ 3100 + 4200 + 3700 + 4500

    Average demand =
    (2100 + 3150+ 2600+ 5000+ 2800+ 3300)
    		lakh tonnes
    6

    Average demand =
    18950
    		lakh tonnes
    6

    Average production =
    (1450+ 3660+ 3100 + 4200 + 3700 + 4500)
    		lakh tonnes
    6

    Average production =
    20610
    		lakh tonnes
    6

    Correct Option: C

    According to given graph in question ,
    Sum of demand of the all given companies = 2100 + 3150+ 2600+ 5000+ 2800+ 3300
    Total number of companies = 6
    And Sum of production of the all given companies = 1450+ 3660+ 3100 + 4200 + 3700 + 4500

    Average demand =
    (2100 + 3150+ 2600+ 5000+ 2800+ 3300)
    		lakh tonnes
    6

    Average demand =
    18950
    		lakh tonnes
    6

    Average production =
    (1450+ 3660+ 3100 + 4200 + 3700 + 4500)
    		lakh tonnes
    6

    Average production =
    20610
    		lakh tonnes
    6

    Required difference =
    20610
    		-
    18950
    66

    Required difference =
    1660
    		= 276.7 lakh tonnes
    6

    ∴ Required answer = 275 lakh tonnes
