Question

the strength of a school is 1146 if boy and girl and are in the ratio 4 3 ratio 5 find find the number of each of them​

Answer 1

Answer:

let the numbers of boys be x

and that of girls be y

x +y =1146. -(1)

x/y=4/3

x=4y/3. -(2)

from (1) and (2)

x + y = 1146

4y/3 + y = 1146

(4y + 3y) /3= 1146

7y=3438

y=3438/7

y=491.14 -(3)

from (1)

x + 491.14=3438

x=3438-491.14

x=2946.86

therefore x=2946.86

and y=491.14

please rewrite your question and write the true ratio because number of boys and girls are cannot be in desimal form.

I gaeyou the method you can write your answer yourself.
