Divisibility Rules




  • A number is divisible by 2, when its unit digit is either Even or Zero.
  • A number is divisible by 3, wehen the sum of its digits is divisible by 3.
  • A number is divisible by 4, when the number formed by the two extreme right end digits is either divisible by 4 or both these digits are zeroes.
  • A number is divisible by 5, when its unit digit is either zero or 5.
  • A number is divisible by 6, when it is divisible bye 2 as well as 3.
  • A number is divisible is by 7, if it passes the following Test...
  • Take the last digit in a number.
  • Double and subtract the last digit in your number from the rest of the digits.
  • Repeat the process for larger numbers.
  • Take an Example 357 (Double the 7 to get 14. Subtract 14 from 35 to get 21 which is divisible by 7 and we can now say that 357 is divisible by 7.
    • A number is divisible by 8, when the number formed by its three extreme right end digits is divisible by 8 or when these last three digits are Zeros.
    • A number is divisible by 9, when the sum of its digits is divisible by 9.
    • A number is divisible by 10, when its unit digit is zero.
    • A number is divisible by 11, when the difference between the sums of the alternate digits is either zero or divisible by 11.
    • A number is divisible by 12, when it is divisible by 3 as well as 4.
    • A number is divisible by 13, if sum of 4 times the digit in units place and the number in the remaining part is multiple of 13.
    • If the difference of 5 times the digit in units place and the number in the remaining part is 0 or multiple of 17, then the number is divisible by 17.
    • If the sum of double the digit in units place of a given number and number in the remaining part is multiple of 19, then the given number is divisible of 19.

    Decimals

    Some times, you have to  convert or express the given percentages in the form of decimals. It is not such a difficult task as we think. Have a look at the following.

    1% = 1/100 = 0.01   (if two zeros are given, just move the decimal pointer two places left)
    2% = 2/100 = 0.02 = 1/50 (the simplification of 2/100)
    3% = 3/100 = 0.03 
    4% = 4/100 = 0.04 = 1/25
    5% = 5/100 = 0.05 = 1/20
    6.25% = 6.25/100 = 0.0625 = 1/16 
    7% = 7/100 = 0.07
    7.5% = 7.5/100 = 0.075
    10% = 10/100 = 0.1 = 1/10
    12.5% = 12.5/100 = 0.125 = 1/8
    20% = 0.2 = 1/5 
    21% = 0.21
    25% = 0.25 = 1/4
    30% = 0.3 = 3/10
    33.33% = 33.33/100 = 0.3333 = 1/3
    37.5% = 0.375 = 3/8
    40% = 0.4 = 2/5
    50% = 0.5 = 1/2
    60% = 0.6 = 3/5
    62.5% = 0.625 = 5/8
    66.66% = 66.66/100 = 2/3
    75% = 0.75 = 3/4
    80% = 0.8 = 4/5
    87.5% = 0.875 = 7/8
    100% = 1
    125% = 1.25 = 1 1/4
    150% = 1.5 = 1 1/2
    200% = 2


    How to Prepare Reasoning for Bank Exams ?



    Look At The below Picture : 







                       
    What Do you See ?





     If you see the Glass of water HALF FULL : It is called Optimism


     If you see the Glass of water HALF EMPTY : It is called Pessimism

     If you see the Girl instead of the Glass :  It is Guy-ism !!! :P



    Now, what if I say that the Glass is Completely Full???

                          It is called REASONING. Check the Below Picture.

                                                     
    Ok, Now Lets go into our Subject. The Reasoning is probably the most important section of the bank exams because Most of us face problem in this section as we find it difficult to finish the section on time. We often found it difficult to decide whether our answer is correct one or not. What is the problem here? Lack of practice. You sit and try to solve some problems. You do 2 or 3. Later you feel that those are very easy and you don't even need preparation for them. SO our suggestion to you is, please don't underestimate any topic. Prepare well. First of all lets have a look at the topics we should cover for the bank reasoning section.

    Those are



    1. Verbal and
    2. Non Verbal


    VERBAL
    • Number Series
    • Alphabet Series
    • Test of Direction Sense
    • Coding-Decoding
    • Number Ranking
    • Arithmetical Reasoning
    • Problem on Age Calculation
    • Blood Relations
    • Analogy
    • Decision Making etc.

    NON-VERBAL


    • Non Verbal Series
    • Relationship with Other figures
    • Grouping Identical Figures
    The Reasoning part of the exam has been designed to know how well can you think in stress situation. They will make you CONFUSE and asks about your girl friend's birth date. Now here the problem is not only remembering the girl friend's birth date, but also NOT to be confused when they asked you about that ;)  Ok jokes apart. 
    There are some points  you should keep in mind while solving problems on Aptitude and Reasoning. They are
    • Not to be confused
    • Manage the Time
    • Skip the Difficult questions
    • Be patient while tackling with difficult paper
    • Dont be nervous
     Thats all friends.  All of us know these points , but the problem is with the Applicability. Ok now lets start preparing for the Reasoning.

    How to Prepare Reasoning Questions for Bank Exams Bank Exams Reasoning Topics Shorts

    The structure of the English Paper

    English language section of Bank Exams contains Two Parts.


    1. Objective
    2. Descriptive


    First of all We shall discuss about Objective type. In Objective type, They ask questions about
    Functional Grammar :
             Again we can decide this Functional Grammar into several parts. Those are
                                                  • Speech
                                                  • Voice
                                                  • Degrees
                                                  • Sentences
                                                  • Parts of Speech
                                                  • Articles
                                                  • Tenses
                                                  • Phrases
                                                  • Classes
                                                  • Miscellaneous


     • Comprehension : Comprehend means "To Understand". Here they check your ability to understand the given passage (Its always good to read the given passage for 2 or 3 times before answering it).


    Vocabulary : In this they will ask
                                                         • Wordpower
                                                         • Synonyms
                                                         • Antonyms


    Jumbled Sentences : In this, they will  jumble 5 or 6 sentences of a paragraph. You should put them into the correct order.
    • Fill in the Blanks : Here they will give you some sentences with blanks, and you should fill the blanks with appropriate words.


    Sentence Completions : These are also similar to filling the blanks. But the difference is, here they give you half of the sentence and you should add the remaining sentence from the options


    Friends, this is the basic structure of the English paper of Bank Exams. The most important rule while attending any English question in a competitive exam is that never look for the answer in the option, first read the question and have the strength to find its answers without looking into options after you get the answer check that in option and choose it. But if you go for option directly you will just get confused because examiner sets options in such a way that you feel all the options are correct this will drop your confidence and you will definitely opt for a wrong option. Hope this article helped you... Thats all for now friends... Have a Good Day.

    Shortcuts in Division

    There are so many types of divisions are there. Lets have a look.

    Division by parts --> Imagine you have Rs.874 . You have to give that to your two children.
    874/2    [We can write this 874 as 800+74 (for our convenience)
    = 800/2 + 74/2
    = 400 + 37
    = 437 

    Division using the factors of the divisor: "this is also called as Double Division"

    70/14
    = (70/7)/2    (Because 7 and 2 are the factors of 14)
    = 10/2
    = 5

    Division using Fractions:

    132/2
    = (100/2 + 32/2) ( here we've broken the given fraction into two separate fractions)
    = (50 + 16)
    = 66

    Division by 5 :

    Note: if you have to divide any number with 5, then divide it by 100 and then just multiply by 20
    1400/5
    = (1400/100) x 20
    = 14 x 20
    = 280

    Division by 10 (Its very simple, just move the decimal point one place to the left)

    0.5/10
    = 0.05 

    Division by 50 ( Just divide with 100 then multiply by 2)

    2100/50
    = (2100/100) x 2
    = 21 x 2
    = 42

    700/50
    = (700/100) x 2
    = 7 x 2
    = 14

    Division by 100 (just move the decimal point two places to the left)

    25/100 
    = 0.25

    Division by 500 (just divide with 100 and then multiply with 0.2)

    17/500 
    = (17/100) x 0.2 
    = 0.17 x 0.2
    = 0.034

    Division by 25 (just divide by 100 and then multiply by 4 )

    500/25
    = (500/100) x 4
    = 5 x 4
    = 20

    750/25
    = (750/100) x 4
    = 7.5 x 2 x 2
    = 30

    Shortcuts in Multiplications

    NOTE : These techniques are for Mental Maths. You should do calculations in your mind only. Please avoid using Pen/Pencil and Paper. 




    Multiplication using multiples
    Assume that we should find out the result of 12X15. 
    12 x 15   (Here we can write this 15 as 5x3)
    =  12 x 5 x 3 (now 12x5 becomes 60)
    =  60 x 3 (For this you just calculate 3x6, that is 18 and add one Zero to it. that is 180)
    =  180 (see, how simple it is?)


    Multiplication by distribution 

    Assume that we should find out the result of 12x17
    12 x 17   (Here we can divide this 17 as 10+7. here, multiplying 12 with 17 is same as multiplying 12 with 10 and 7 separately and then adding the results)
    so, we can write it as
    = (12 x 10) + (12 x 7) 
    = 120 + 84
    = 204 


    Multiplication by "giving and taking"
    12 x 47  (Here its little difficult for us to calculate the multiplication of 12 and 47 mentally. so just check for the ROUNDED number nearer to 47. Yes it is 50. so.....

    = 12 x (50 - 3) 
    = (12 x 50) - (12 x 3)  (we have discussed this rule earlier)
    = 600 - 36
    = 564


    Multiplication by 5

    * If we have to multiply a number with 5, just divide the number with 2 and then multiply the result with 10. Confused? Its very simple step actually....
    428 x 5   (Now just divide the number with 2)
    = 428 x 1/2 = 214 (Now multiply it with 10. I mean just add a zero at the end :P)
    = 214 x 10
    = 2140 (This is our result)

    Whats the logic behind this step? 
    Very simple. 
    * Lets say the number is X. 
    * Now we are dividing the number with 2.  so here X becomes X/2. 
    * And then we are multiplying it with 10.  So it will become 10x / 2  
    * Now cancel it with 2. so it becomes 10x / 2 = 5X = 5 multiplied by X. Thats it ;)


    Multiplication by 10  ------------  just move the decimal point one place to the right
    16 x 10
    = 160
    5.9 = 159
    169.93 = 169.3   (Need an explnation for this too??? :P)

    Multiplication by 50 ------ divide with 2 and then multiply by 100
    Well, this is also same process as we did for 5. Here we should add an extra zero. Thats it
    18 x 50
    = (18/2)  = 9
    = 9 x 100
    = 900


    Multiplication by 100 -------- move the decimal point two places to the right
    45 x 100
    = 4500  


    Multiplication by 500-------- divide with two and multiply with 1000 
    21 x 500
    = 21/2 x 1000
    = 10.5 x 1000
    = 10500


    Multiplication by 25 ---------- use the analogy Rs 1 = 4 x 25 Paise
    25 x 14 (just divide the 14 as 10+4)
    = (25 x 10) + (25 x 4) 
    = 250 + 100 --->  Rs2.50 + Rs1
    = 350


    Hey one more thing. Here you can use another technique too. Which we have used for multiplication with 5.
    Multiplication by 25 -----------  Divide by 4 and multiply by 100 

    36 x 25
    = (36/4) x 100
    = 9 x 100
    = 900  
    Multiplication by 11 (if sum of digits is less than 10)
    72 x 11
    = 7+2 =9, it is Less than 10. so,
    = place this term 9 between 7 &2

    = 792 (That's the answer)

    Multiplication by 11 (if sum of digits is greater than 10)
    87 x 11
    =>  8 + 7 = 15 
    because here 15 is greater than 10, first use 5 and then add 1 to the first term 8, 
    which gives you the answer
    = 957 

    Multiplication of numbers ending in 5 with the same first terms (square of a number)
    25 x 25 
    first term = (2 + 1) x 2 = 6
    last term = 25
    answer = 625 ---> square of 25

    75 x 75 
    first term = (7 + 1) x 7 = 56
    last term = 25
    answer = 5625 ---> 75 squared
