BANKING EXAM PREPARATION

Simple interest formula is one of the methods of calculating the interest on a certain amount. First, it is important to recall the concept of interest and ways to calculate it. When you borrow money from a bank, there is an extra amount to be along with the amount you borrowed. That extra money that you pay is called interest. Some money lenders and financial institutions also charge this interest for the money borrowed. There are two types of interest levied upon: Simple Interest, and Compound Interest It should be noted that the simple interest is paid at the end of a specific time period and is always a fixed amount that the borrower has to pay. The   simple interest   is calculated using a formula which is described below along with an example question. Formula for Simple Interest Simple interest is calculated by multiplying the interest rate by the principal amount and the time period which is generally in years. The S.I. formula is given as: Simple Interest (SI) = P × T × R ⁄ 10

HCF and LCM For two numbers, HCF x LCM = product of the two.  HCF of Fractions = HCF of Numerator                               LCM of Denominator  LCM of Fractions = LCM of Numerator                                 HCF of Denominator  Relatively Prime or Co-Prime Numbers: Two positive integers are said to be relatively prime to each other if their highest common factor is 1. Divisibility Rules  A number is divisible by: 2, 4 & 8 when the number formed by the last, last two, last three digits are divisible by 2,4 & 8 respectively. 3 & 9 when the sum of the digits of the number is divisible by 3 & 9 respectively. 11 when the difference between the sum of the digits in the odd places and of those in even places is 0 or a multiple of 11.  6, 12 & 15 when it is divisible by 2 and 3, 3 and 4 & 3 and 5 respectively.  7, if the number of tens added to five times the number of units is divisible by 7.  13, if the number of tens added to four times the number of units is

The approach to solve the questions of this section? Observe alphabets or numbers given in the code keenly. Find the sequence it follows whether it is ascending or descending. Detect the rule in which the alphabets/numbers/words follow. Fill the appropriate letter/number/word in the blank given. Some Basics which we need to learn before solving the questions of this topic are: Letter position  (A=1, B=2, C=3, D=4 …… Y=25, Z=26) Opposite position of letters  (A=26, B=25 …… Z=1) Opposite of each letter  (A is opposite to Z and B is opposite to Y and C is opposite to X …… and so on) Various types on which Coding and Decoding are classified are (as per Bank Exams): Letter Coding Substitution Mixed Letter Coding Mixed Number Coding LETTER CODING: In this type the real alphabets in a word are replaced by certain other alphabets according to a specific rule to form its code. The candidate is required to detect the common rule and answer the questions accordingly. Fo
