  "Average" is a very important topic for any government exam like SSC, Bank , or Railways. Average form an important part of the arithmetic section. Concepts of Averages are used in other sections also. So, we just can't ignore or leave this topic because it is the basis of many important topics. In this article, you will learn about tips and tricks for Averages . Basically Average is equal to the sum of all the given numbers divided by the total of all numbers. This formula may seem easy for smaller numbers but is time-consuming for bigger numbers so we have a trick of "Method of Deviation". Average always lies between the highest number and the lowest number.  Suppose numbers are 68, 75, 78, 84, 95. So here, the Average will always lie between 68 and 95. First, choose any number between 68 and 95 let's say 76, then calculate the deviation of all the numbers from 76. So, in this way, we can calculate the Average in a much faster way. Let there are n consec

We can't leave this topic untouched because a lot of questions come from this topic. Mensuration is a division of mathematics that deals with geometric figures like cones, cubes, spheres, etc. We are generally asked about the volume, area, length of these figures, and shapes. Mensuration is nothing but the measurement of parameters of 2D and 3D figures. Lateral surface area is the area of all the surfaces excluding the area of base and top. Lateral surface area is also called the curved surface area in the case of cone or sphere. Total surface area refers to the sum of lateral surface area and the area of top and bottom.  In this article, we are providing you with the formulas of the most commonly used

Whether we are preparing for SSC , Bank PO, Railways, we generally get stuck in lengthy calculations which is very time-consuming, so here, we will see the method of Digital Sum which is very easy and convenient for speeding up our calculation. So let's check this out. How to do:- The digit-sum method can be used to check answers involving different arithmetic operations like multiplication, division, addition, subtraction, squares, square roots, cube roots. The procedure is very simple. We have to convert a given number into a single digit by repetitively adding up all the digits of that number till we get a single-digit number. You have to keep on adding the numbers until you get a single-digit answer. Rule Underlying in this method:- We already know that a no. is divisible by 9 if the sum of the digits is divisible by 9. So, in the digit sum method, we have the single-digit value of the total number which represents the remainder obtained on dividing that number by 9. And any nu
