    1. Answer:  1440

    Explanation:-
    The total angle of the circle = 360 degree
    The sum of the angle of the children who used transport = 120 + 72 + 24
    =  216 degree
      The angle at the center representing people walking  = 360 – 216
    = 144 degree

    Hence, the answer is (1) 1440

    2. Answer:  (1) 20%

    Explanation:-
    The angle of children whose are using scooter = 72 degree

    Then, the percentage of children using scooter = 72 x 100/360
    = 20%

    Hence, the answer is (1) 20%.

    3. Answer:  (2) 50

    Explanation:-
    If 10 students come by car,
    Then, the angle of students are come by car  = 24 degree
    The angle of students are come by bus = 120 = 24 x 5

    Then, the number of students are come by bus = 10 x 5
    = 50

    Hence, the answer is (2) 50.

    4. Answer: (2) 450

    Explanation:-
    If 180 students come walking to school ,

    Then, the total number of students in the school = 180 x 360/144
    = 450

    Hence, the answer is (2) 450.
