The area of a rectangular plot of land is 81754sq. m. If its breadth is 2143m, find its length.
Answer
Given:
Area of rectangular plot of land = 81754 m2=54089 m2
Breadth = 2143 m=487 m
Length of rectangular plot of land = ?
Length of rectangular plot of land = (Area of rectangular plot of land) ÷ (Breadth)
Substituting the values in above, we get:
Length of rectangular plot of land = 54089 m2÷487 m
=(54089×874) m=(547×14) m=5×147×4 m=5188 m=3753 m[Reciprocal of 487 is 874][Simplifying 2565 and 345 ⇒ Divide by 15]

The area of a sheet of paper is 623107 sq. cm. If its length is 29107cm, find its width.
Answer
Given:
Area of a sheet of paper = 623107 cm2=106237 cm2
Length = 29107 cm=10297 cm
Width = ?
The sheet of paper will be in rectangular shape,
∴ Area = Length x Width
Width = Area ÷ Length
Substituting the values in above, we get:
Width = 106237 cm2 ÷ 10297 cm
=(106237×29710) cm=(16237×2971) cm=1×2976237×1 cm=2976237 cm=21 cm[Reciprocal of 10297 is 29710][Simplifying 10 and 10 ⇒ Divide by 1]
∴ The width of a sheet of paper = 21 cm
A bundle of 500 sheets of paper has a net weight of 2103kg. Find the weight of 1 sheet of paper.
Answer
Given:
Total weigth = 2103 kg=1023 kg
Number of sheets = 500
Weigth of 1 sheet of paper = (Total weigth) ÷ (Number of sheets)
Substituting the values in above, we get:
Weigth of 1 sheet of paper = 1023 kg ÷ 500
=(1023×5001) kg=10×50023×1 kg=500023 kg[Reciprocal of 500 is 5001]
∴ The weigth of 1 sheet of paper = 500023 kg
A car travels 28321 km in 432 hours. How far does this car go in 1 hour, travelling at the same speed?
Answer
Given:
Total distance = 28321 km=2567 km
Total time = 432 hours=314 hours
Distance covered in 1 hour = ?
Distance covered in 1 hour = (Total distance) ÷ (Total time)
Substituting the values in above, we get:
Distance covered in 1 hour = 2567 km÷314 hours
=(2567×143) km=(281×23) km=2×281×3 km=4243 km=6043 km[Reciprocal of 314 is 143][Simplifying 567 and 14 ⇒ Divide by 7]
∴ The distance covered in 1 hour = 6043 km
The product of two fractions is 8257. If one of them is 3151 find the other.
Answer
Given:
Let the two fractions be p and q.
p = 3151=1546
Let the other fraction be q.
p x q = 8257=25207
q = 25207 ÷ p [Solving for q]
Substituting the value of p, we get:
q = 25207÷1546
=25207×4615=5207×463=59×23=5×29×3=1027=2107[Reciprocal of 1546 is 4615][Simplifying 15 and 25 ⇒ Divide by 5][Simplifying 207 and 46 ⇒ Divide by 23]
