Top 5 Numerical Ability Shortcuts for BPSSC Exams

Introduction to BPSSC Exams

The Bihar Police Subordinate Services Commission (BPSSC) conducts various exams for recruitment in the police department. One of the most competitive exams is the Bihar Havildar Clerk exam. To crack this exam, it's essential to have a strong foundation in numerical ability.

Numerical ability is a crucial section in BPSSC exams, and mastering shortcuts can help you solve questions quickly and accurately. In this article, we'll discuss the top 5 numerical ability shortcuts for BPSSC exams.

Shortcut 1: Multiplication Tables

Multiplication tables are a fundamental concept in mathematics. Learning multiplication tables up to 20 can help you solve questions quickly. You can use the following trick to learn multiplication tables:

• Start with the multiplication table of 2: 2, 4, 6, 8, 10, ...
• Then, move to the multiplication table of 3: 3, 6, 9, 12, 15, ...
• Continue this process until you reach the multiplication table of 20.

By learning multiplication tables, you can solve questions like 14 × 17 = ? quickly.

Shortcut 2: Squares and Cubes

Squares and cubes are essential concepts in mathematics. Learning squares and cubes up to 20 can help you solve questions quickly. You can use the following trick to learn squares and cubes:

• Start with the square of 1: 1² = 1
• Then, move to the square of 2: 2² = 4
• Continue this process until you reach the square of 20.
• Similarly, learn the cubes of numbers up to 20.

By learning squares and cubes, you can solve questions like 17² = ? or 14³ = ? quickly.

Shortcut 3: Algebraic Identities

Algebraic identities are useful in solving questions quickly. Some common algebraic identities include:

• (a + b)² = a² + 2ab + b²
• (a - b)² = a² - 2ab + b²
• (a + b)(a - b) = a² - b²

By learning these algebraic identities, you can solve questions like (14 + 17)² = ? quickly.

Shortcut 4: Geometry Formulas

Geometry formulas are essential in solving questions quickly. Some common geometry formulas include:

• Area of a rectangle: length × width
• Area of a triangle: (base × height) / 2
• Circumference of a circle: 2πr

By learning these geometry formulas, you can solve questions like the area of a rectangle with length 14 cm and width 17 cm.

Shortcut 5: Data Interpretation

Data interpretation is a crucial section in BPSSC exams. To solve data interpretation questions quickly, you need to learn how to analyze data and draw conclusions. Some common data interpretation questions include:

• Bar graphs
• Pie charts
• Line graphs

By learning data interpretation shortcuts, you can solve questions like the percentage increase in sales over the past year.

Conclusion

In conclusion, mastering numerical ability shortcuts is essential to crack BPSSC exams. By learning multiplication tables, squares and cubes, algebraic identities, geometry formulas, and data interpretation shortcuts, you can solve questions quickly and accurately. Remember to practice regularly and focus on common topics to improve your numerical ability.
