# How to Find Number of Trailing Zeros in a Factorial or Product

June 12th, 2020 by

In this Number of trailing Zeros blog post, We would like to cover these two ideas: Number of trailing zeroes in a Product or Expression Number of trailing zeroes in a factorial (n!) But before I begin, let us first try to understand what exactly are ‘trailing zeroes’. It is nothing else but the number of zeroes at the end. I do not want to sound pedantic but on many occasions when you see a question which asks about, “What is the number of zeroes in ___” it is incorrect, because it should actually say – “What is the number of trailing zeroes?” or “What is the

# Successive Division – Problems and Solved Examples for CAT Exam

June 11th, 2020 by

SUCCESSIVE DIVISION: If the quotient of the dividend is taken and this is used as the dividend in the next division, such as division is called “successive division”. A successive division process can continue up to any number of steps until the quotient in a division became zero for the first time, i.e., the quotient in the first division is taken and divided in the second division; the quotient in the second division is taken as the dividend in the third division; the quotient in the third division is taken as the dividend in the fourth division and so on. If we say that 2479 i

# Coordinate Geometry (Concepts, Formulas and CAT questions)

June 9th, 2020 by

There are all sorts of ways that we can find the measurements of lines and angles. We can use rulers to measure lines and protractors to measure angles. In coordinate geometry, we can use graphs and coordinates to find measurements and other useful information about geometric figures. A coordinate graph is a rectangular grid with two number lines called axes. The x-axis is the horizontal number line and the y-axis is the vertical number line. The axes intersect at the origin which is the point (0,0). Coordinate Geometry Formulas: Now, Let us have a look at some formulas fo

# Basic Trigonometry Concepts 2 – Questions and Solved Examples for CAT

June 8th, 2020 by

In the earlier part of trigonometry series, we had seen basic concepts and some questions. In this part we will see some additional Examples to understand how to deal with CAT questions Example 1: 5sinx + 12cosx + s is always greater than or equal to 0. What could be the possible smallest value of s? a.) 13 b.) 10 c.) 6 d.) 2 Solution: 5sinx + 12cosx ≥ -s ⇒ 13(5/13sinx+12/13cosx) ≥ -s                  (Since 5,12 and 13 are Pythagorean triplets,) ⇒ 5/13 = cosA ⇒ 12/13 = sin A ⇒ 13(sinx cosA + sinA cosx) ≥ -s ⇒ 13(sin(x + A))
