Question

viii) In a class of 42 students,the number of boys is 2/5 of the girls. Find the number of boys and girls. ​

Answer 1

Answer:

Boys - 12

Girls - 30

Step-by-step explanation:

Total number of students = 42

Number of girls  = x

Number of boys = 2x/5

Now x+2x/5 = 42

5x/5+2x/5 = 42

7x/5 = 42

7x= 42×5

7x = 210

x = 210/7

x= 30

So the number of girls is 30

Then number of boys = 2 (30)/5

2×6

Boys= 12

Answer 2

Step-by-step explanation:

Number of boys = 12

Number of girls = 30
