However, a candidate can perform well in this section very accurately and efficiently if he/she prepares by using SSC CGL Maths Short Tricks and Formulas which help them to cover the Maths section easily and quickly. In this blog, we have provided some Short Tricks and Formulas by which candidates can easily solve the SSC CGL Maths very easily.

## SSC CGL Maths Short Tricks and Formulas

Solving SSC CGL Maths without using Short Tricks will take so much time which is not good for the aspirants during the exam. As we all know, Maths is a type of section that takes so much time for solving the questions and do calculations. SSC CGL Maths topics include Average, Data Interpretation, Number System, Time & Work, Ratio, Time, Speed & Distance, Simplification, Pipe & Cistern, Successive Discount, Geometry, Trigonometry, Mensuration, Profit & Loss. These topics are included in the SSC CGL Maths so if a candidate understands the short tricks related to these topics then that candidate can save his/her time during the exam. Below we have provided some important SSC CGL Maths Short Tricks and Formulas. Candidates are advised to follow them and go through the blog very carefully.

## SSC CGL Maths Short Tricks

If a candidate wants to solve the SSC CGL Exam within time then they must learn the SSC CGL Maths Short Tricks to attempt the questions and solve them quickly. It is possible that one can solve the questions without using short tricks but as per the experts, using the short tricks is very important it not only saves time but also increases the accuracy of the exam. Below we have provided the SSC CGL Maths Short Tricks candidates must follow:

1. If a number is first decreased by a% and then by b%, then the net change in percent is (–ve sign for decrease):

2. The average of ‘n’ consecutive natural numbers starting from 1 i.e. Average of 1,2,3, …..n:

3. Mean Proportion – Let x be the mean proportion between a and b, then a:x::x:b

So, the mean proportion of a and b = √(a × b)

4. If cost price of ‘x’ articles is equal to selling price of ‘y’ articles, then Selling Price = x, Cost Price = y

5. When two successive discounts are given, the overall discount is

6. If a certain sum P amounts to Rs. A1 in t1 years at rate of R% and the same sum amounts to Rs. A2 in t2 years at same rate of interest R%. Then,

7. If A and B can do a work in ‘x’ days, B and C can do the same work in ‘y’ days, C and A can do the same work in ‘z’ days. Then total time taken, when A, B and C work together

8. Time taken by 1st man to reach B after meeting 2nd man at C is ‘t1 ’ and time taken by 2nd man to reach A after meeting 1st man at C is ‘t2 ’ then:

9. The largest number which when divide the numbers a, b and c give remainders as p, q, r respectively is given by:

**H.C.F. of (a – p), s(b – q) and (c – r)**

10. The recurring decimal numbers of type 0.x or 0.xyz may be converted to rational form as

## SSC CGL Maths Formulas

SSC CGL Maths Formulas is very important to solve the questions very quickly. Candidates are advised that they should be prepared with all the formulas learned and practiced already to avoid any mistakes during the exam. Candidates must make a small note and write down all the formulas in that note. Candidates must keep revising the formulas daily.

### Important Algebraic Formulas

- (a + b)2 = a2 + 2ab + b2 = (a – b)2 + 4ab
- (a – b)2 = a2 – 2ab + b2 = (a + b)2 – 4ab
- (a2 + b2) = (a + b)2 – 2ab = (a – b)2 + 2ab
- (a2 – b2) = (a – b)(a + b)
- 2(a2 + b2) = (a + b)2 + (a – b)2
- (a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca
- (a + b – c)2 = a2 + b2 + c2 + 2ab – 2bc – 2ca
- (a – b – c)2 = a2 + b2 + c2 – 2ab + 2bc – 2ca
- (a + b)3 = a3 + b3 + 3ab(a + b)
- (a – b)3 = a3 – b3 – 3ab(a – b)
- (a3 – b3) = (a – b) (a2 + ab + b2) = (a – b)3 + 3ab(a – b)
- (a3 + b3) = (a + b) (a2 – ab + b2) = (a + b)3 – 3ab(a + b)
- 2(a2 + b2) = (a + b)2 + (a – b)2
- a3 + b3 + c3 – 3abc = 1/2 (a + b + c) {(a – b)2 + (b – c)2 + (c – a)2}
- If a + b + c = 0, then a3 + b3 + c3 = 3abc

**Clear Basic Concept:**It should be the first step for a candidate. Before diving into the advanced level of SSC CGL Maths Preparation candidates must be familiar with basic concepts of maths. It is very important because if a candidate starts with an advanced level then it will be very difficult for him/her to understand the topics and solve the questions. So, candidates are advised to clear the concepts first, understand them, solve simple level questions then go ahead with the advanced level.**Write Down the Formulas:**Candidates are highly advised to make a small notebook in which they can write all formulas topic-wise. Candidates can find the topics in this blog we have already shared above. Writing down the formulas will help the candidates to revise them in a sequence way and regularly. It will also help them during the last days of exams during the revision time.**Practice the Short Tricks:**Learning the SSC CGL Short Tricks and Formulas is not enough. Candidates must understand it is the first step along with this they need to practice the short tricks regularly.

So, when candidates practice the short tricks as much as they can it will help them to understand the question pattern deeply and they can also apply the short tricks during the exam easily and quickly.**Read Question Properly and Carefully:**Maths is a type of section in the SSC CGL where candidates need to play with digits, formulas, tricks, etc. A misread of a single digit can lead to the whole calculation being wrong along with the time that the candidate devotees to solve that question. So, candidates are highly advised to read the question very carefully and write down the value very carefully then solve the question.**Time Management:**As we all know the SSC CGL Exam is a time-bounded exam in which candidates face 100 questions in 60 minutes and SSC CGL Maths is the section that took so much time. Candidates need to practice the question in a way that they can manage their time also. As per experts, candidates should devote 20 minutes to the SSC CGL Maths section. So, as the candidates practice more it will help them to manage their time also.
