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?
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)
To find out how many curtains of 3 meters can be made from a roll of curtain cloth, here's what we need to do:
1. Determine the total length of the curtain cloth. Since nine curtains of 4 meters in length can be made, the total length of the roll is 9 * 4 = 36 meters.
2. Now, calculate how many curtains of 3 meters can be made from the available length of 36 meters. Divide the total length by the length of each curtain:
Number of curtains = Total length / Length of each curtain
= 36 meters / 3 meters
= 12 curtains
Therefore, from the roll of curtain cloth, it is possible to make 12 curtains, each measuring 3 meters in length.
