A total of $ 204 was collected from boys and girls of a class of 150 students . If each boy contributes $1 and each girl contributes $1.5 then find the no of boys and girls in the class.
Let the number of boys be B and Girls be G
total no of students = 150
B + G = 150 ... (i)
Total contribution = 204
Each boy gives $1 and Each girl gives $1.5
1B + 1.5G = 204 ...(ii)
Subtract (i) from (ii)
0.5 G = 54
[spoiler]G = 108
B = 42[/spoiler]
