  1. Use a Venn diagram, showing two overlapping circles labelled M and S
    From your data 75 passed Math and twice that many or 150 passed Science
    Let x be the number who passed both
    so after filling in the data on the Venn,
    (75-x) + x + (150-x) = 156
    x = 69

    take it from there
