Question

10 computer operator can type 120 page in 2 hours how many operators Should to work if the job is to be completed in 30 minutes​

Answer 1

Answer:

40

Step-by-step explanation:

10 computer operator can type 120 page in 2 hours,

Here person=10,page=120,time=2

i.e. m₁=10,w₁=120,h₁=2 (m₁=person,w₁=page,h₁=hour)

we have to find m₂=? where w₂=120,time=1/2 hours ( w₁=w₂,30 mins=1/2 hours)

According to the formula,

m₁w₂h₁=m₂w₁h₂

10×120×2=m₂×120×1/2

∴ m₂=10×2×2=40
