    On the basis of given graph in question ,
    Total income of companies M and N = Rs. (35 + 50) crores = Rs. 85 crores
    Total expenditure of companies M and N = Rs. (45 + 40) crores = Rs. 85 crores

    Correct Option: A

    On the basis of given graph in question ,
    Total income of companies M and N = Rs. (35 + 50) crores = Rs. 85 crores
    Total expenditure of companies M and N = Rs. (45 + 40) crores = Rs. 85 crores
    Profit/Loss = Total income - Total expenditure = 85 - 85 = Rs. 0
    Therefore , there is no loss and no profit .

    From the given bar diagram , we see
    Income of company Q in 2001 = Rs. 40 crores
    Expenditure of company Q in 2001 = Rs. 30 crores
    Profit of Q = 40 - 30 = 10 crores

    Profit percent of company Q =
    10
    		 × 100
    30

    Correct Option: A

    From the given bar diagram , we see
    Income of company Q in 2001 = Rs. 40 crores
    Expenditure of company Q in 2001 = Rs. 30 crores
    Profit of Q = 40 - 30 = 10 crores

    Profit percent of company Q =
    10
    		 × 100
    30

    Profit percent of company Q =
    100
    		= 33
    1
    		%
    33

  1. If the income of company Q in 2001 was 10% more than that in 2000 and the company had earned a profit of 20% in 2000, then its expenditure in 2000 (in crores Rs.) was :

    As per the given bar graph ,
    Income of company Q in 2001 = Rs. 40 crores
    From question , we have

    Income of company Q in 2000 =
    100
    		× 40 = Rs.
    400
    		 crores
    11011

    If expenditure in 2000 be Rs. y crores,
    Profit % = Income – Expenditure× 100
    Expenditure

    Profit % =
    ( 400 / 11 ) - y
    		 × 100
    y

    ⇒
    20
    		=
    1
    		=
    400 - 11y
    100511y

    Correct Option: E

    As per the given bar graph ,
    Income of company Q in 2001 = Rs. 40 crores
    From question , we have

    Income of company Q in 2000 =
    100
    		× 40 = Rs.
    400
    		 crores
    11011

    If expenditure in 2000 be Rs. y crores,
    Profit % = Income – Expenditure× 100
    Expenditure

    Profit % =
    ( 400 / 11 ) - y
    		 × 100
    y

    ⇒
    20
    		=
    1
    		=
    400 - 11y
    100511y

    ⇒ 5 × 400 – 55y = 11y
    ⇒ 66y = 2000
    ⇒ y =
    2000
    		 = Rs. 30.30 crores
    66

    Hence , expenditure in 2000 be Rs. 30.30 crores .

    On the basis of given graph in question ,
    Total income = Rs. (35 + 50 + 40 + 40 + 50) crores = Rs. 215 crores
    Total expenditure = Rs. (45 + 40 + 45 + 30 + 45) crores = Rs. 205 crores

    ∴ Profit percent = Income – Expenditure× 100
    Expenditure

    Correct Option: E

    On the basis of given graph in question ,
    Total income = Rs. (35 + 50 + 40 + 40 + 50) crores = Rs. 215 crores
    Total expenditure = Rs. (45 + 40 + 45 + 30 + 45) crores = Rs. 205 crores

    ∴ Profit percent = Income – Expenditure× 100
    Expenditure

    Profit percent = 215 – 205× 100
    205

    Profit percent =
    1000
    		 = 4.88%
    205
