    I have another q:

    All 100 students in a year group sat a test in english and a test in science.
    Everyone passed atleast one of the tests.82 of the students passed the english test and 57 passed the science test.
    Show this information in a venn diagram.

    I think you need to do some arithmetic

    if s = science only
    e = english on;y
    and b = science and english

    then you can do s + e + b = 100
    etc
