    Gaurav Seth 5 years, 9 months ago

    Step-by-step explanation:

    Let the set of students who offered mathematics, statistics and physics  be M, S and P respectively. Let a be number of students who offered all 3 subjects.  So we get

    40 – a  +  a + 20 – a  + 8 = 65

    So 68 – a = 65

     A = 3

    Now students who offered Mathematics  

     15 + 10 – a + a + 40 – a

     65 – a

    65 – 3 = 62

    Now students who offered Statistics

    12 + 10 – a + a + 20 – a

    42 – a  

    42 – 3 = 39

    Now students who offered any of three subjects are

    15 – 12 + 8 + 10 – a + 40 – a + 20 – a + a

    105 – 2 a  

    105 – 2 x 3

    105 – 6

    = 99

    So number of students who did not offer any subjects were 100 – 99 = 1
