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 1

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

Hence , there are 72 students there .

Answer 2

Answer:

72 students

Step-by-step explanation:

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

A/q

5x = 3x + 18

=> 5x - 3x = 18

=> 2x = 18

=> x = 18/2

= 9

No. of boys = 5x = 5×9 = 45

No. of girls = 3x = 3×9 = 27

Now,

Total no. of students = 45 + 27

= 72 Ans...

Hence,

There are total 72 students .
