    It depends which gender they feel like. Psychology triumphed over physiology.

    m = 30 = f/2+10 

    f = (30-10)*2= 40

    m+f = 30+40 = 70

    The number of girls=(30-10)*2=40

    =>

    the total number of members in the club=30+40=70.

    30 is 10 more than 20 .

    20 is half of 40 .

    30 + 40 = 70 .

    There are 70 boys and girls in the club .

    let b - boys

       g - girls

    b = g/2 + 10

    when b = 30

    30 = g/2 + 10

    60 = g + 20

    60 - 20 = g

    g = 40

    g + b = 30 + 40 = 70

    Therefor, there are 70 members in a tennis club..

    Let g be the number of girls.

    You are told the number of boys is 10 more than half the number of girls:

    g/2 + 10

    And you are also told there are 30 boys:

    g/2 + 10 = 30

    Subtract 10 from both sides:

    g/2 = 20

    Multiply both sides by 2:

    g = 40

    There are 30 boys and 40 girls. Add those together to get the total number of members.

    Answer:

    70 boys and girls are in the club.

    B=G/2+10

    B=30

    B-10=G/2=20>>G=40

    B+G=30+40=70

    70 people total, 30 boys and 40 girls. 

    30-10=20   20x2=40
