Mensuration

Mensuration Questions For Bank Clerk Prelims

Mensuration is an important part of the Quantitative aptitude section for most of the bank exams. Mensuration is the branch of geometry that deals with the measurement of area, length, or volume in 2D and 3D shapes. The 2D shapes can be drawn in a plane like square, rectangle, triangle, circle, etc. … Mensuration includes computation using mathematical formulas and algebraic equations. Mensuration is a division of mathematics that studies geometric figure calculation and its parameters such as area, length, volume, lateral surface area, surface area, etc. It outlines the principles of calculation and discusses all the essential equations and properties of various geometric shapes and figures. A 2D diagram is a shape laid down on a plane by three or more straight lines or a closed segment. Such forms do not have width or height; they have two dimensions-length and breadth and are therefore called 2D shapes or figures. Of 2D forms, area (A) and perimeter (P) is to be determined. A 3D shape is a structure surrounded by a variety of surfaces or planes. These are also considered robust types. Unlike 2D shapes, these shapes have height or depth; they have three-dimensional length, breadth, and height/depth and are thus called 3D figures. 3D shapes are made up of several 2D shapes. Often known as strong forms, volume (V), curved surface area (CSA), lateral surface area (LSA), and complete surface area (TSA) are measured for 3D shapes. 

There are 10 basic mensuration formulas in Mathematics out of which, 5 are for 2D figures and 5 are for 3D figures. Q3: What are the topics in mensuration? Mensuration deals with obtaining the perimeter, area, and volume of different kinds of geometric figures. Both 2D and 3D figures are included in mensuration.

Answers :

1) Answer: C

The radius of the circle=r

2*22/7*r=132

r=132*7/22*1/2

r=21 cm

The side of the square=21*5/3=35 cm

The perimeter of the square=4*35=140 cm


2) Answer: D

4a = 48

a = 12 cm

Length of the rectangle = 4/3 * 12 = 16 cm

Breadth of the rectangle = 48/2 – 16 = 8 cm

Area of the rectangle = 16 * 8 = 128 cm2


3) Answer: A

Length of the rectangle = 5x

Breadth of the rectangle = 4x

5x * 4x = 500

x2 = 25

x = 5 m

Side of the square = 5*5 + 5 = 30 m

Perimeter of the square = 4a = 4*30 = 120 m


4) Answer: B

Circumference of the circle = 88m

2πr = 88

r = 14m

Length of the rectangle = 14m

Breadth of the rectangle = 14*5/7 = 10m

Perimeter of the rectangle = 2(l+b) = 2(14+10) = 48m


5) Answer: A

The side of the square=40/4=10 cm

The height of the cylinder=10-5=5 cm

22/7*r2*5=770

r2=49

r=7 cm


6) Answer: C

Side of the square = (576)(1/2)= 24 cm

Perimeter of the rectangle = 2 * (24 + 18) = 84 cm

Circumference of the circle = 84 + 4 = 88 cm

Radius of the circle = 88 * 7/22 * 1/2 = 14 cm

Area of the circle = 22/7 * 14 * 14 = 616 cm2


7) Answer: A

Let the radius of the cylinder=x cm

The volume of the cylinder=3080 cm3

22/7*x*x*5=3080

x2=196

x=14

The perimeter of the square=4*14=56 cm


8) Answer: A

Let the radius of the cylinder = r

Height of the cylinder = h

Total surface area of cylinder = 2πr(r+h)

Curved surface area of cylinder = 2πrh

2πr(r+h) / 2πrh = 5/4

4r+4h = 5h

4r= h

Required % = (h-r)/h*100 = (4r-r)/4r * 100 = 75%


9) Answer: A

Ratio of the length to breadth of the rectangle = 125:100 = 5:4

(5x + 4x) * 2 = 90

x = 5

Length of the rectangle = 5 * 5 = 25 cm

Breadth of the rectangle = 4 * 5 = 20 cm

Side of the square = 20 cm

Area of the square = 20 * 20 = 400 cm2

Area of the rectangle = 25 * 20 = 500 cm2

Difference = 500 – 400 = 100 cm2


10) Answer: C

r * (22/7 + 2) = 108

r = 21 cm

1056 = 2 * 22/7 * 21 * h

Height of the cylinder = 8 cm

Volume of the cylinder = 22/7 * 21 * 21 * 8

= 11088 cm3

Answers :

11) Answer: B

Original area of rectangle = 100

New area = 100 * 125/100 * 90/100 = 112.5

Area of rectangle is 12.5% increased


12) Answer: C

Breadth of the rectangle = 2a

Length of the rectangle = 150/100 * 2a = 3a

2a * 3a = 1176

a = 14 cm

Perimeter of the rectangle = 2 * (42 + 28) = 140 cm

Side of the square = 140/5 = 28 cm

Perimeter of the square = 4 * 28 = 112 cm


13) Answer: D

4a = 48

a = 12 cm

Length of the rectangle = 4/3 * 12 = 16 cm

Breadth of the rectangle = 48/2 – 16 = 8 cm

Area of the rectangle = 16 * 8 = 128 cm2


14) Answer: B

Circumference of the semi-circle = 360cm

r(π+2) = 360

r (22/7 +2) =360

Therefore, radius of the semi-circle = 70cm

Diameter of the semi-circle = 140cm

Side of the square = 3/(5 ) (140) = 84cm

Perimeter of the square = 4a = 4*84 = 336 cm


15) Answer: A

248 = 2 * (3x * 2x + 2x * 5x + 5x * 3x)

31x2 = 124

x2 = 4

x = 2

Breadth of the rectangle = 2 * 3 = 6 cm

Length of the rectangle = 6 + 4 = 10 cm

Area of the rectangle = 6 * 10 = 60 cm2


16) Answer: B

Let side of the cube = ‘a’ cm

So, total surface area of the cube = 6a2 cm2

And volume of the cube = a3 cm3

From the question:

6a2 = a3 * (75/100)

6a2 = 3a3/4

a = 8 cm

So, total surface area of the cube = 6 * 8 * 8 = 384 cm2


17) Answer: C

22/7 * r * r = 616cm2

Radius of the circle = 14 cm= Radius of the cone

Height of the cone = 6/7 * 14 = 12 cm

Volume of the cone = 1/3 * 22/7 * 14 * 14 * 12

= 2464 cm3


18) Answer: C

2 * (5x + 4x) = 126

x = 7

Breadth of rectangle = 7 * 4 = 28 cm

Diameter of the circle = 28 cm

Radius of the circle = 28/2 = 14 cm

Area of the circle = 22/7 * 14 * 14 = 616

Area of the rectangle = 35 * 28 = 980

Difference = 980 – 616 = 364 cm2


19) Answer: D

22/7 * 12 * l = 180 * 22/7

l = 15

Height of cone = √152 – 122

= 9 cm

Radius of cylinder = 7/6 * 12 = 14 cm

Height of cylinder = 9 + 3 = 12 cm

Volume of cylinder = 22/7 * 14 * 14 * 12

= 7392 cm3


20) Answer: C

Radius of the circle = x

After increased the radius = x * 120/100 = 6x/5

22/7 * 6x/5 * 6x/5 – 22/7 * x * x = 271.04

22/7(36x2 – 25x2/25) = 271.04

11x2 = 2156

x = 14

Circumference of circle = 2 * 22/7 * 14

= 88 cm
