The mensuration Questions for SBI PO are among the toughest in the aptitude section of the bank PO and clerk exams. Mensuration for the SBI PO exam tests your ability to solve complex 2D and 3D geometry problems, primarily appearing in the Mains exam arithmetic section or as Data Interpretation caselets. High-scoring questions test combinations of formulas, percentage changes, and ratio comparisons across multiple shapes. This topic has maximum weightage in every bank exam. Answering these mensuration questions is not that easy unless you practice regularly. For effective preparation, make sure to download the free PDF we offer and try to practice each set regularly.

Common Types of Mensuration Questions For SBI PO

1. Shape Conversion (Melting & Recasting)

• Total volume remains constant when a 3D object is melted and recast into another shape.

• Common Scenario: A large cylinder or sphere is melted to form multiple small cones, spheres, or bullets.

• Exam Variant: Find the number of smaller objects formed; find a missing dimension of the new shape

2. Inner & Outer Paths (Fencing & Costing)

• Questions involve boundaries, pathways, and maintenance costs.

• Common Scenario: A rectangular or circular park has a uniform-width path inside or outside.

• Exam Variant: Find the area of the path; Calculate the cost of gravelling the path or fencing the park at a given rate.

3. Perimeter-to-Area Relationship

• Uses a common perimeter/circumference to relate different shapes.

• Common Scenario: Perimeter of a rectangle equals the perimeter of a square; Circumference of a circle equals the perimeter of a triangle.

• Exam Variant: Find the area, diagonal, or side length of the other shape.

4. Percentage Changes in Dimensions

• Tests the effect of percentage changes in dimensions on area or volume.

• Common Scenario:

• • Radius of a sphere increases by 10%.

  • Length of a rectangle increases while breadth decreases.

• • Exam Variant: Find the net percentage increase or decrease in surface area or volume.

5. Combination of Shapes

• Involves one shape fitting inside or around another.

• Common Scenario:

• • Circle inscribed in an equilateral triangle.

  • Sphere inside a cube.

  • Cone carved out of a cylinder.

• • Exam Variant: Find the remaining volume; find the ratio of areas or volumes.

6. Mensuration-Based Data Interpretation (DI)

• Data Interpretation based on mensuration concepts.

• Common Scenario: Table with dimensions (radius, height, length, etc.) of rooms, tents, or containers (A, B, C, D).

• Exam Variant: Solve multiple questions involving missing dimensions, ratios, percentages, capacities, and surface areas.

• Memorize standard values (π, √2, √3) and common ratios.

• Practice volume and surface area conversions regularly.

• Learn shortcuts for percentage changes in dimensions. 

• Focus on shape conversion and combination of solids. 

• Practice fencing, pathway, and cost-based questions. 

• Solve perimeter-to-area relationship problems. 

• Strengthen Data Interpretation (DI) based on mensuration.

Important Tips 

• Write down all formulas before starting practice. 

• Read the question carefully and identify the given shape(s). 

• Draw a rough diagram whenever possible. 

• Keep units consistent throughout the calculation. 

• Use π = 22/7 or 3.14 only as instructed. 

• Remember: Melting and recasting conserve volume. 

• For percentage-change questions, area and volume do not change linearly.

• Check whether the path is inside or outside the figure before applying formulas.
