    Answer:

    Step-by-step explanation:

    91.66 % is science

    remaining 8.34% is commerce + arts

    8.34%/2 =4.17 %

    4.17%=20 students

    4.17% commerce +4.17% arts =8.34% remaining

    20+20=40

    now 8.34% =40

    then 100% =480

    so 480 is the ans.

    Enjoy.

    Given:

    91.66% opted for science

    To find:

    The total number of students.

    Solution:

    Let the total number of students are 100%

    It is given in the question that 91.66% opted for science and

    half of the remaining opted for commerce

    We have remaining 8.34% students and half of it is 4.17%

    Remaining 20 opted for arts

    so, other 4.17% will be equal to 20

    • 4.17% —– 20
    • 100% —– 20×100/4.17
    • 100% —– 479.616

    So we have total 479 students
