In 1000 sq. meter of land a farmer cultivated 765 kg of rice with the wastage of 23.5%. I) Find the weight of the wastage. II) F
LenKa [72]

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
