Answer:
i. 179.775 kg
IIa)the weight=585.225 kg
IIb) percentage=75.6%
3)=30240 kg
Step-by-step explanation:
From the question were given the total area of the land as 1000 sq. meter
Amount of cultivated rice= 765 kg
the percentage of wastage rice =23.5%.
But we can convert the amount of the wastage rice from percentage to kilogram which is
23.5/100=0.235
Then to kilogram 0.235× 765 kg= 179.775 kg
Then amount of wastage rice= 179.775 kg
I)Find the weight of the wastage. ?
The amount of wastage rice is the conversion of it's percentage to kilogram which I did above
Then amount of wastage rice= 179.775 kg
II) Find the weight and percentage of rice cultivated.
Since we know amount of wastage as 179.775 kg, then the amount of cultivated will b difference between the cultivated and wastage=765 - 179. 775 = 585.225 kg
Then it's percentage is the substraction of the percentage of wastage from 100%
= 75.6%
3)If the area has been increased 40 times in size, how much rice will be cultivated (excluding the wastage)
Increase in the land in 40 times= 40×1000= 40,000sm
Then the rice cultivated= 75.6% ×40000
=30240 kg
