  1. If the family expends Rs. 750 per month on food, what is the annual expenditure of this family on education?
    1. 2150
    2. 1022.50
    3. 2250
    4. 1400

    Here as per graph food expenditure, 40% = Rs. 750
    ⇒ 10% = 10 x 750/40 = Rs. 187.50

    Correct Option: C

    Here as per graph food expenditure , 40% = Rs. 750 per month
    ⇒ 10% = 10 x 750/40 = Rs. 187.50 per month
    As per graph 10% is the expenditure on education.
    ∴ Annual expenditure (12 months) of the family on education = 187.50 x 12 = Rs. 2250

    As per graph,
    Expenditure on clothing = 20 % of total expenditure.

    Correct Option: B

    As per graph,
    Expenditure on clothing = 20 %
    Expenditure on clothing = Total expenditure x 20 %
    Expenditure on clothing = 4500 x 20/100 = Rs. 900
    Expenditure on clothing = 45 x 20 = Rs. 900

    As per graph,
    other expenses = 15 % of total expenditure.

    Correct Option: B

    As per graph,
    other expenses = 15 % of total expenditure.
    As we know that the angle made on center in a circle is 360°
    Since 100% made an angle 360° in a circle.
    therefore 1% made an angle 360° / 100 in a circle.
    therefore 15% made an angle 15 x 360° / 100 in a circle.
    Central angle for 15% =15 x 36° / 10
    Central angle for 15% =3 x 36° / 2
    Central angle for 15% =3 x 18° = 54°

  1. What is the ratio of total expenses on rent and clothing to the total expenses on medicines and other expenses of this family?
    1. 2 : 3
    2. 3 : 4
    3. 3 : 5
    4. 3 : 2

    As per graph
    Expenditure on rent and clothing = 10% + 20% = 30%
    Expenditure on medicine and other expenses = 5% + 15% = 20%

    Correct Option: D

    As per graph
    Expenditure on rent and clothing = 10% + 20% = 30%
    Expenditure on medicine and other expenses = 5% + 15% = 20%
    ∴ Ratio = 30% : 20% = 3 : 2
