Question

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) Find the weight and percentage of rice cultivated. 3) If the area has been increased 40 times in size, how much rice will be cultivated (excluding the wastage)

Answer 1

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
