  1. Investment of company ‘B’ in 1997 is more by 40% than that in the previous year. Income in 1997 was what % of the investment in 1996?










  1. View Hint View Answer Discuss in Forum

    Required % = Income of company B in 1997x 100%
    the investment of company B in 1996

    Correct Option: B

    From above given graph ,
    Let the investment of company B in 1996 be Rs P lakhs.

    Investment of company B in 1997 = P + P × 40% = Rs.7P
    5

    Income of company B in 1997 = Rs.9 × 7P
    55

    Required % = Income of company B in 1997 x 100
    the investment of company B in 1996

    Required % = 63P/25x 100% = 252%
    P

  1. Income of company ‘A’ in 1995 is equal to the investment of the company ‘B’ in 1996. What is the ratio of the investment of company ‘A’ in 1995 to the investment of company ‘B’ in 1996?










  1. View Hint View Answer Discuss in Forum

    Let I95( A ) = E96( B ) = Rs. P lakhs
    The investment of company ‘B’ in 1996 = Rs. P lakhs
    Required ratio = The investment of company ‘A’ in 1995 : The investment of company ‘B’ in 1996

    Correct Option: C

    Let I95( A ) = E96( B ) = Rs. P lakhs
    The investment of company ‘B’ in 1996 = Rs. P lakhs

    The investment of company ‘A’ in 1995 = P × 100 = 100P
    155155

    Required ratio = The investment of company ‘A’ in 1995 : The investment of company ‘B’ in 1996
    = 100P/155 = 20 : 31
    P

Direction: Study the following graph to answer the given questions.

  1. What was the difference in the expenditures of the two companies in 1999–2000?










  1. View Hint View Answer Discuss in Forum

    The given graph depicts only the percent profit earned by the two companies over the given years.

    Correct Option: D

    The given graph depicts only the percent profit earned by the two companies over the given years. So we need Income information also to calculate the expenditure of the companies for this years. Hence the given information is insufficient to answer the question.
    Hence, answer cannot be determined .

  1. If the income of Company X in 1998–99 was equal to the expenditure of Company Y in 2001–2002, what was the ratio of their respective profits?










  1. View Hint View Answer Discuss in Forum

    Thus, required ratio = profit earned by company X in this year : profit earned by company Y in 2001–02

    Correct Option: E

    Suppose in the year 1998–99 expenditure of company X = रु a
    Then profit earned by company X in this year = रु (30% of a) Hence, income of company X = रु (130% of a)

    = रु 130 x a
    100

    Again, expenditure of company Y in 2001–02
    = रु a + 130
    100

    Hence, profit earned by company Y in 2001–02
    = रु a × 130 × 50
    100100

    Thus, required ratio = profit earned by company X in this year : profit earned by company Y in 2001–02
    = 30a/100 = 30 × 100 x 100 = 30 = 6 : 13
    ( 50 x 130a )/10000100 × 130 × 5065

  1. For Company Y, in which year is the percent of increase in percent profit over that of previous year the highest?










  1. View Hint View Answer Discuss in Forum

    Percent of increase in percent profit over that of the previous year for the given years is as follows :
    Year

    1998 - 99 :
    (20 - 15)
    		x 100 = 33.33%
    15

    1999 - 00 :
    (30 - 20)
    		x 100 = 50%
    20


    Similarly calculate for the others years and compare.

    Correct Option: C

    Percent of increase in percent profit over that of the previous year for the given years is as follows :
    Year

    1998 - 99 :
    (20 - 15)
    		x 100 = 33.33%
    15

    1999 - 00 :
    (30 - 20)
    		x 100 = 50%
    20

    2000 - 01 : = 0 %
    2001 - 02 :
    (50 - 30)
    		x 100 = 66 2/3 %
    30

    2002 - 03 :
    (60 - 50)
    		x 100 = 20%
    50

    You do not need to do any rough work. See the graph and search for steep rise in the line joining the two ∆’s.
