let the no. of girls needed to make 450 garlands in 2 hours be x
no. of garlands(p)= 150,450
no. of girls(q)=10,x
no. of hours(z)=5,2
thus, it is an direct variation as many girls can make many garlands
p/q=150/10=450/x
150× x=10×450
150x=450×10
x=450×10/150
x=30
therefore, 30 girls can complete 450 garlands in 2 hours
