Question

~~~~~~~~~~~~

The ratio of boys to girls in a group is 5:3. If there are 18 more boys than girls, work out how many people there are in total

Answer : 72 students

~~~~~~~~~~~~~~~~~~~~~~~~~~~

Step-by-step explanation:

Let the ratio of boys to girls be 5x : 3x

A/q

no. of boys = 18 + no. of girls

=> 5x = 18 + 3x

=> 5x - 3x = 18

=> 2x = 18

=> x = 18/2

= 9

Now,

No. of boys = 5x

= 5 × 9

= 45

No. of girls = 3x

= 3 × 9

= 27

Total = 45 + 27 = 72

Answer:

72

Step-by-step explanation:

number of boys = 18 + number of girls

5x = 18 + 3x

5x - 3x = 18

2x = 18

x = 18/2

9

NUMBER of boys = 5x

5 × 9

= 45

Number of girls = 3x

=3 × 9

= 27

45 + 72 = 72
