## Maths Tricks & Tips for Competitive Exams

Here is a compilation of few tricks and examples which you can follow to score well in Maths for Competitive Exams :

**1. Substitute variable with 0 or 1**

Substituting variables with simple numbers like 0 or 1 can assist you in solving algebra questions in the section of Maths for competitive exams.

Quantity A = 8x + 2

Quantity B = 8(x+2)

a) Quantity B > A

b) Both quantities are equal

c) The relationship cannot be determined

d) Quantity A>B

Trick: Substitute variable “x” with 0

**The answer is option b**

#### 2. **Plugging-in numbers**

Plugging-in numbers is a common trick that you should know while practising Maths for competitive exams. The basic idea behind this strategy is to substitute variable with easy and manageable numbers like 1, 2, -1 etc. and find the answer. Let us understand using an example.

**x is an even integer. Which of the following is the sum of two even integers greater than 4x+2?**

a) x+8

b) 8x+6

c) 8x+4

d) 8x+2

**Trick: **Follow these steps:

Step 1: Choose a number. In this case, let us take x=2 (as it says “even integer”)

Step 2: Substitute this value in the above equation. This gives us 9

Step 3: Look for even integers greater than 9. Which brings us to 10 and 12

Step 4: Since the question says, “sum of two even integers greater than 4x+2” therefore, add the integers i.e. 10 + 12 = 22

*The correct answer lies where the sum equals to 22, i.e. option b*

#### 3. **Speed Problems**

Always remember that if two objects with speed x and y respectively are moving in the same direction, then their relative speed will be **x-y.**

However, if the same two objects move in the opposite direction then, their relative speed will be **x+y**.

#### 4. **Back Substitution**

Back Substitution is a helpful trick that can help you in acing Maths for competitive exams. This technique can be used when you are not sure about which formulas or methods to use to solve the question.

**What can be the possible value of y so that |(2-|y-2|)| = 7**

a) -4

b) -7

c) 3

d) 11

e) 5

Let us start with the first option. On substituting y= -4, we get the final answer as 8

Let us now substitute y=-7. This gives 7 on both sides.

Thus, if you are not familiar with any technique to solve the question, you can simply start substituting values into the equation.

*Answer of the example is option a *

*Here are some Number Series questions for you!*

**Tips to Improve Maths for Competitive Exams**

Let’s impart you with the key tips you can follow to nail your preparation for the section of Maths for Competitive Exams.

**Always Keep a List of Important Formulas on Your Desk**

Maths without formulas is like Pizza without cheese. Instead of cramming up the formulas at the last moment, it is better to go through them as many times as you can. Also, try to memorise only few important formulas and not the entire list.

**Master Important Topics First**

Study smart, not hard. Almost all the topics in Maths for competitive exams are important but there are a few concepts that are commonly asked. Identify those areas and practise them thoroughly.

**Break the Shapes**

In the section of Maths for competitive exams, you are bound to get confused in questions with complex and intertwined shapes. Simply redraw the shapes separately on a rough sheet and then answer the question.

**Memorize the Right Stuff**

Remember multiplication tables at least up to 30 and learn the square as well as cube roots for numbers till 40. These hacks can help you save time from difficult calculations.

**Follow the Mantra of Practice**

When you take competitive tests that are set in a specific time frame, it improves your speed and helps you identify the areas where you still lag. So, keep practising the key concepts until you feel confident enough to crack them.
