Given:
Total number of students = 1400
The ratio of boys to girls is 3 to 4 for the school.
To find:
The number of boys and girls.
Solution:
We have, Boy : Girls = 3:4.
Let number of boys be 3x and number of girls be 4x.
Total number of students = 1400
[tex]3x+4x=1400[/tex]
[tex]7x=1400[/tex]
Divide both sides by 7.
[tex]x=200[/tex]
Now,
Number of boys [tex]=3\times 200=600[/tex]
Number of girls [tex]=4\times 200=800[/tex]
Therefore, the number of boys is 600 and number of girls is 800 in the Berkmar Middle school.
