    ∵ 100% ≡ 360°

    ∴ 10% ≡
    360
    × 10 = 36°
    100

    ∴ Corresponding angle for expenditure on health and education
    ≡ 36 + 54 = 90°
    ∵ 360° ≡ $ 100000 crores
    ∴ 90° ≡
    100000
    × 90°
    360

    = $ 25000 crores

    Correct Option: A

    ∵ 100% ≡ 360°

    ∴ 10% ≡
    360
    × 10 = 36°
    100

    ∴ Corresponding angle for expenditure on health and education
    ≡ 36 + 54 = 90°
    ∵ 360° ≡ $ 100000 crores
    ∴ 90° ≡
    100000
    × 90°
    360

    = $ 25000 crores

    Corresponding angle to the number of students who go to institute on foot
    = 360° – (216° + 54° + 18°) = 72°
    ∴ Required answer

    =
    72 × 800
    = 160
    360

    Correct Option: A

    Corresponding angle to the number of students who go to institute on foot
    = 360° – (216° + 54° + 18°) = 72°
    ∴ Required answer

    =
    72 × 800
    = 160
    360

    Corresponding angle to number of students who do not use institute bus = 360° – 216° = 144°
    ∵ 360° ≡ 800

    ∴ 144° ≡
    800
    × 144° = 320
    360

    Correct Option: D

    Corresponding angle to number of students who do not use institute bus = 360° – 216° = 144°
    ∵ 360° ≡ 800

    ∴ 144° ≡
    800
    × 144° = 320
    360

    Corresponding angle to the number of students who travel by public bus = 54°
    ∵ 360° ≡ 800

    ∴ 54° ≡
    800
    × 54° = 120
    360

    Correct Option: B

    Corresponding angle to the number of students who travel by public bus = 54°
    ∵ 360° ≡ 800

    ∴ 54° ≡
    800
    × 54° = 120
    360

    ∵ 144° ≡ 180 students

    ∴ 360° ≡
    180
    × 360
    144

    = 450 students

    Correct Option: B

    ∵ 144° ≡ 180 students

    ∴ 360° ≡
    180
    × 360
    144

    = 450 students
