## Maths Tricks & Shortcut For Competitive Exams

Maths tricks and shortcuts are the easiest and fastest ways in which you can solve mathematical problems in the upcoming Government exams.

The quantitative aptitude or the numerical ability section is most commonly a part of all major Government Exams, and if a candidate can get shortcut tricks to solve this section quickly, he may be able to score a higher overall percentage in the examination.

Here’s a comprehensive list of math tricks and shortcuts specifically tailored for competitive exams like bank exams, SSC exams, or any other similar tests:

**10 Simple Maths Tricks & Shortcuts**

### Arithmetic Tricks:

**Multiplication:****Multiplying by 11:**For any two-digit number $ab$, $ab×11=a(a+b)b$. Example: $34×11=3(3+4)4=374$.**Multiplying by 9:**Multiply the number by 10 and subtract the number itself. Example: $47×9=47×(10−1)=470−47=423$.**Multiplying by 5:**Divide the number by 2 and then multiply by 10. Example: $36×5=(36÷2)×10=18×10=180$.

**Division:****Dividing by 5:**Multiply the number by 2 and then move the decimal point one place to the left. Example: $175÷5=(175×2)÷10=350÷10=35$.**Dividing by 9:**Use the repeating decimal method or the divisibility rule for 9. Example: $567÷9=63$.

**Percentage:****Percentage Increase/Decrease:**Use the formula $New Value=Original Value×(1±Percentage/100)$. Example: Increase of 20% on 150 = $150×(1+20/100)=180$.

### Algebraic Tricks:

**Simplification:****Factorization:**Factorize the expression to simplify calculations. Example: $x_{2}−4x+4=(x−2_{2}$.

**Quadratic Equations:****Finding Roots:**Use the quadratic formula $x=ab±b−ac$. Example: Solve $x_{2}+5x+6=0$.

### Geometry Tricks:

**Area and Perimeter:****Rectangle/Area:**Area of rectangle = Length × Breadth. Example: $Area=12×8=96$ square units.

**Volume and Surface Area:****Cube/Volume:**Volume of cube = Side × Side × Side. Example: $Volume=5×5×5=125$ cubic units.

### Data Interpretation Tricks:

**Reading Graphs:****Bar Graphs:**Pay attention to the scale and read data accurately. Example: Calculate the number of students in each class from a given bar graph.

**Pie Charts:****Percentage Calculation:**Use the angle subtended by each sector to calculate percentages. Example: Calculate the percentage of expenditure on food from a given pie chart.

### General Tips:

**Practice Regularly:**Regular practice enhances speed and accuracy in using these shortcuts effectively.**Know When to Apply:**Understand the context and suitability of each trick or shortcut in different types of questions.**Use Mock Tests:**Take mock tests to simulate exam conditions and practice applying these shortcuts under time constraints.

By mastering these math tricks and shortcuts, you can streamline your problem-solving approach and improve your performance in competitive exams. Regular practice and familiarity with these techniques will build your confidence and efficiency in tackling mathematical problems effectively.
