Question

the numbers of boys and girls in a class are in the ratio 5:6 .the numbers of boys is 5 less than the numbers of girls . what is the total numbers of students in that class ?

Answer 1

Answer:

Total number of students in the class are 55

Step-by-step explanation:

Let the common multiple be x

Total students in class = 5x + 6x = 11x

Given,

5x + 5 = 6x

x = 5

Therefore,

Total students = 55

Answer 2

Step-by-step explanation:

Let no. of boys = 5x

and no. of girls = 6x

According to question

6x - 5x = 5

So, x = 5

Now, no. of boys = 5x = 5*5 = 25

and no. of girls = 6x = 6*5 = 30

So, total no. of s = no. of boys + no. of girls = 25+30 = 55 students
