    Answer:

    20

    Step-by-step explanation:

    Percentage of female students = 40/100

    ∴, Percentage of male students = 60/100

    Male students – female students = 40

    Let the common multiple be x

    No. of male students = (60/100) * x

    No. of female students = (40/100)*x

    ∴, (60/100 * x ) – (40/100 * x) = 40

    (60x-40x)/100= 40

    20x/100 = 40

    20x= 40*100

    x= 400/20

    x=20

    ∴ No. of male students = (60/100) * 20

                                          = 12

    No. of female students = (40/100)* 20

                                           = 8

    Total number of students = 12 +8= 20
