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.

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
