Question:

A maths club has 40 members. The number of girls is 5 less than 2 times the number of boys. How many are boys? How many are girls?

The number of girls in the maths club is 25

The number of boys in the maths club is 15

Step-by-step explanation:

Given:

Total number of members in the maths club = 40 member

The Number of girls is 5 less than 2 times the number of boys

To Find:

Number of boys and girls = ?

Solution:

Let the number of boys be x

Then the number of girls = 2x - 5

Also we know that the total number of boys is

=> x+(2x-5) =40

=> 3x -5 = 40

=> 3x = 40 +5

=> 3x =45

=>

=> x = 15

Now the number of girls

=> 2(15)-5

=>30-5

=>25

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
