​

Answer 1

Answer:

the number of boys is 3 and number of the girls is 7

Answer 2

Answer:

boys =3

girls=7

Explanation:

let,

boys =x

girls =y

y=x+4

y-x=4..........[1]

given total strength is 10

then, x+y=10.........[2]

substitute[2] in [1]

2x+4=10

2x=10-4

x=6/2=3

then, boys =3

girls =3+4 = 7

therefore, boys =3 and girls= 7
