Question

10 girls can prepare 150 garland in 5 hours how many girls are needed to 450 garland in 2 hours.

Answer 1

Answer:

75

Step-by-step explanation:

10×5/150 = x×2/450

by solving

x= 75

Answer 2

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
