List of Important Mathematics Formulas
This PDF contains important formulas from the following chapters of Mathematics:
- Speed, Distance & Time
- Profit & Loss
- Time, work & wages
- Mensuration 2 D and 3
Speed Time and Distance
Speed is simply defined as the distance covered per unit time. Mathematically, it is defined as :
- Speed = Distance Travelled / Time Taken
- The formula of Time in terms of distance and Speed: Time = Distance/ Speed
- The formula of Distance in terms of Speed and Time: Distance = (Speed X Time)
- It is very important to know the importance of the unit while solving these kinds of problems.
SI Unit for Speed: Meter per second
SI Unit for Distance: Meter
SI Unit for Time: Second
All the formulas of speed, time, and distance are interrelated. One needs to connect the information given in the problems wisely and this can be done easily with good practice.
Profit, Loss, and Discount:
Profit, Loss, and Discount is yet another crucial topic of the Arithmetic section of Quantitative Aptitude. You may also find the application of this topic in certain Data Interpretation questions as well.
The percentage is an important part of Quantitative Aptitude. Whether it is DI, Profit & Loss, SI-CI, or Allegation, etc. all these chapters with the help of percentage can be solved easily. You can go through the basics of percentage and previous year asked questions. We will study the percentage in two parts. In this article, we will discuss the basics of the percentage.
A percentage is a number or ratio expressed as a fraction of 100. It is proportion per hundred.
1. When we say 35 percent in mathematical notation we write 35%.
2. When we want to express this in mathematical form, 35% means 35 per 100 or (35/100).
Important: 50% of 20 can be written 20% of 50 as well.
You can also represent % into decimal, 50% = 0.5

What is Average?
The result obtained by adding several quantities together and then dividing this total by the number of quantities is called Average.
The main term of average is an equal distribution of value among all which may distribute persons or things. We obtain the average of a number using a formula that is the sum of observations divided by the Number of observations.
- Average: = (Sum of observations / Number of observations).
Trigonometry formulas are sets of different formulas involving trigonometric identities, used to solve problems based on the sides and angles of a right-angled triangle. These trigonometry formulas include trigonometric functions like sine, cosine, tangent, cosecant, secant, cotangent for given angles.
