    Answer:

    no.of student who do not like any subject- 10

    number of students who like both subject- 5

    Step-by-step explanation:

    Let the number of student who like both sub be x

    then number of the student who do not like any subject- 2x

    Total no.of students- 50

    No. of students likes math- 20

    number of student who like science – 15

    total number of students who like Math and Science – 35

    so rest of the student to not like any subject and some student like both subject

    So A/Q- x + 2x=15

    3x=15

    x=15/3

    x=5

    so number of students who like both subject is equal to X so the number of students who like both subject are 5

    and number of a student who do not like any subject is equal to 2 X so they are 10 in numbers
