From a roll of curtain cloth ,9 curtains each of length 4 metres can be cut.If the curtains needed are of 3 metres long,how many curtains can be made out of this cloth?

Answer 1

So you have 9x4 = 36 meters in total of cloth (as found by the first cutting of curtains). So now if they didn't make any cuts to the 36 meters of cloth with the 4m curtains you still have 36 meters, and now just divide it into 3 meter curtains (36 divided by 3)
