If us 250 is divided among 180 children each boy gets us 2 and each girl gets us 1 the

let boy = x and girl = y
from question
x+y=180---(1)
2x+y=250---(2)
on solving we will get x=70 and y=110

70 boys.
70 boys will get 140 us$. and 110 girls will get 110$..
so total will be 250 $.

LET BOYS ARE X AND GIRLS ARE Y
FROM PUZZLE X+Y=180
and 2X+Y=250
AFTER SOLVE X=70;
AND Y=110;
SO NO OF BOYS =70

If all had been girls the total would have been $180. But the total is $250 - $180 = $70 more.
For each girl replaced by a boy the total increases by $2 - $1 = $1.
Hence the number of boys has to be $70/ $1 = 70.

boys and girls ratio is 7:11
so no of boys are 7/18*180=70
ratio can be obtained as boys and girls is (2-250/180):(250/180-1)=7:11
so answer is 70

let no. of boys is x, and that of girls is y.
so, x+y=180 and 2x+y=250
solving them, x=35

from the given question, let's jut frame one simple equation...
consider there are X boys, and (180-X) girls..
(X)2 + (180-X)1 =250
by solving we get X= 70... that gives the count of boys.

let x be the number of boys and y be the number of girls.
then x+y=180---------eq(1)
2x+y=250---------eq(2)
by solving these two we get the answer as X(boys)=70
