question kya bro bata do yaar

Answer 2

Answer:

let the no.og girls be X

and the no.of boys be y

then

according to 1st condition

x+y=10

let y=0

we get X=10

and let y=5

we get X=5

according to 2nd condition

x=y+4

let y=6

we get X=10

and let y=2

we get x =6

A1/A2 not equal to b1/B2

hence it is consistent and one solution
