  Significance of English Section in SBI Clerk 2018 Exam
Significance of English Section in SBI Clerk 2018 Examination
Hello dear students as you all are well aware about the SBI Clerk Prelims Exam2018 and the date has already been rearranged on 23rd, 24th and 30th of June 2018. We know as you people are preparing hard for the exam so we would like to inform you all that there are major changes in the pattern of SBI Clerk Examination that will be observed this year are the introduction of section timing for the Prelims exams too and elimination of sectional cut off. 

 Previously students used to save their timing by spending a maximum of 15 minutes on the English Section and the time they would save this way was used up on solving the complex questions of Reasoning Ability and Quantitative Aptitude Sections which are thought to be more time-consuming. But from now this trick is not going to help you anymore because you have to spend 20 minutes on each of the three sections that means 20 minutes out of total 60 minutes have to be given exclusively to English Section as per the SBI Notification. But don’t be disappointed because there is a silver lining in every dark cloud, isn't it? So, why to look at the dark side of a thing rather to look at the bright side of it. Focus on the positive attitude of everything. As this way you have the enough time to spend on the English section to and you can score best in English Section as you will enough of time to deeply go through the questions and thus crack the questions with a higher accuracy rate.

So students don’t be disappointed because there is always a solution to every difficult situation as somebody had said “when there is a will there is a way”.  The one who desire anything he had to chase that thing. Always use the opportunities and never make excuses. Now you have to make the strategies according to the examination pattern as you have enough time for English section that is20 minutes for 30 questions so why not to have a full command on English language. Deeply go through the English grammar, comprehension, reading section etc. learn the things from their base; prepare the things like a master. So for helping you in this we are providing you some useful tips that can help you in making a command on English section for SBI Clerk 2018 Examination:

·         Put your practice more and more on solving the English questions with the help of different Mobile Applications as you all have smart phones.
·         Clear your basics of English language and learn the things from their roots because as your basics will be clear I am sure you are going to rock. You still have 2 months to grip the maximum of the nuts and bolts of this language so work hard and make the best use of these 2 months and practice most of the questions so you can manage to attempt the maximum number of questions in this section.
·         Those students who are having a weak hand in English grammar can attempt the reading comprehension first as you have the enough time for reading the paragraphs thoroughly, understand it well and then solve the questions. As there is no extra need of grammar knowledge in solving the reading comprehension section, one has to read it and to comprehend it by using his/her common sense.
·         In reading comprehension section you have to keep in mind to solve the question first based on vocab and phrase and after solving these go through the sections which need deep penetration.
·         For the cloze test these subjects should be on your finger tips such as subject-verb agreement, preposition, and verbs. These  topics are going to help you in  solving other grammar questions also. So focus on these topics and work hard to have a mastery on this.
·         For boosting up your vocabulary you have to work on the newspaper. Read a good newspaper regularly and the new words which you come across note them in a diary and try to use them in your daily life routine, there is no best way to increase your vocabulary other than this. Try this on a regular base and this will help you for sure.
All the best to all the participants. Work Hard along with smart work.

TYPES OF BANK ACCOUNTS IN INDIAN BANKS
a)     Savings Bank Account
b)     Current Deposit Account
c)      Fixed Deposit Account
d)     Recurring Deposit Account.
e)     FCNR Deposit Account
f)       NRO Account
g)     NRE Account
Savings Bank Account in India
This type of account can be opened with a minimum initial deposit that varies from bank to bank. Money can be deposited any time in this account. Withdrawals can be made either by signing a withdrawal form or by issuing a cheque or by using ATM card. Normally banks put some restriction on the number of withdrawal from this account. Interest is allowed on the balance of deposit in the account. The rate of interest on savings bank account varies from bank to bank and also changes from time to time. A minimum balance has to be maintained in the account as prescribed by the bank. Interest rate is paid to the account holders on daily balance basis.
Current Deposit Account
This type of bank account used to save current deposits. Big businessmen, companies and institutions such as schools, colleges, and hospitals have to make payment through their bank accounts. Since there are restrictions on number of withdrawals from savings bank account, that type of account is not suitable for them. They need to have an account from which withdrawal can be made any number of times. Banks open current account for them. On this deposit bank does not pay any interest on the balances. Rather the account holder pays certain amount each year as operational charge. For the convenience of the account holders banks also allow withdrawal of amounts in excess of the balance of deposit. This facility is known as overdraft facility.
Features of Current Accounts :
 (a) The main objective of Current Account holders in opening these account is to enable them (mostly businessmen) to conduct their business transactions smoothly.
(b) There are no restrictions on the number of times deposit in cash / cheque can be made or the amount of such deposits;
(c)  Usually banks do not have any interest on such current accounts.   However, in recent times some banks have introduced special current accounts where interest (as per banks' own guidelines) is paid
(d) The current accounts do not have any fixed maturity as these are on continuous basis accounts
Fixed Deposit Account (also known as Term Deposit Account)
This type of bank account in India used to save money for long period. Many a time people want to save money for long period. If money is deposited in savings bank account, banks allow a lower rate of interest. Therefore, money is deposited in a fixed deposit account to earn interest at a higher rate.
Recurring Deposit Account
This type of account is suitable for those who can save regularly and expect to earn a fair return on the deposits over a period of time. While opening the account a person has to agree to deposit a fixed amount once in a month for a certain period. The total deposit along with the interest therein is payable on maturity. However, the depositor can also be allowed to close the account before its maturity and get back the money along with the interest till that period. The rate of interest allowed on the deposits is higher than that on a savings bank deposit but lower than the rate allowed on a fixed deposit for the same period.
NRO Deposit Account
NRO stand for Non Resident Ordinary saving account
The Non Resident Ordinary Account (NRO Account) is a Savings / Current. Recurring Deposit / Fixed Deposit bank account held in India, in Indian Rupees. NRO account is opened by any person resident outside India only who want to earn attractive rate of interest in India and also have some earnings in India (such as rent income, dividend, pension, etc).This account is best suited for NRI or PIO who have some earnings in India as these earnings are deposit in NRO account .NRO account is only operated in Indian currency only .Average monthly balance in NRO saving account is Rs1,50,000. NRIs can remit up to 1 million per calendar year. Banks are free to determine their interest rates on savings deposits under Ordinary Non-Resident (NRO) Accounts. However, interest rates offered by banks on NRO deposits cannot be higher than those offered by them on comparable domestic rupee deposits
NRE Account
NRE stands for Non Resident External Account. The Non Resident External Account (NRE Account) is a Savings / Current. Recurring Deposit / Fixed Deposit bank account held in India, in Indian Rupees. Such accounts can be opened only by the NRI. Balances held in NRE account are fully repairable. With effect from March 1, 2014, interest rates offered by banks on NRE deposits cannot be higher than those offered by them on comparable domestic rupee deposits 
Notes:

b) Maximum Interest rate is given on FD A/c.

BOATS AND STREAMS QUANTITATIVE APTITUDE STUDY NOTES
Today’s topic is BOATS AND STREAMS; this is the one of the most important topics in quantitative aptitude section in Bank and SSC exam. You should know how to calculate Boats and stream questions and answers in very short time for bank exam. From this chapter around 1-2 questions are given in the SBI and IBPS exams. For this here we are providing shortcut tricks and quicker method to calculate BOATS AND STREAMS in very short time. We also providing the theorems which are elaborate short trick formula’s for stream boat.
Introduction to Boats and Streams: Normally, by speed of the boat or swimmer we mean the speed of the boat or swimmer in still water. If the boat ( or swimmer ) moves against the stream then it is called upstream and if it moves with the stream, it is called downstream.
If the speed of the boat (or the swimmer) is x and if the speed of the stream is y then, while upstream the effective speed of the boat = x – y and while downstream the effective speed of the boat = x + y.
Here are the theorems and formula’s with short tricks for boats and streams:
Theorem 1:
if x km per hour be the man’s rate in still water, and y km per hour the rate of the current.  Then
x + y = man’s rate with current
x – y = man’s rate against current.
Adding and subtracting and then dividing by 2.
x = ½ ( man’s rate with current + his rate against current)
y = ½ ( man’s rate with current – his rate against current)

hence, we have the following two facts:
(i)                A man’s rate in still water is half the sum of his rates with and against the current.
(ii)              The rate of the current is half the difference between the rates with and against the current.
Ex. 1: A man can row upstream at 10 km/hr and downstream at 16 km/hr. Find the man’s rate in still water and the rate of the current.
Solution: Rate in still water = ½ (10 + 6) = 13 km/hr
Rate of current = ½ (16 – 10) = 3 km/hr
Ex. 2: A man swims downstream 30 km and upstream 18 km, taking 3 hrs each time. What is the velocity of current?
Solution: Man’s rate downstream = 30/3 km/hr = 10 km/hr
Man’s rate upstream = 18/3 km/hr = 6 km/hr
Velocity of stream = (10 – 6) / 2
= 2 km/hr
Ex. 3: A man can row 6 km/hr in still water. It takes him twice as long to row up as to row down the river. Find the rate of the stream.
This questions we can solve by three methods, we will discuss one by one;
Solution: method 1:
Let man’s rate upstream = x km/hr
Then, man’s rate downstream = 2x km/hr
Man’s rate in still water = ½ (x + 2x) km/hr
3x/2 = 6
Or x = 4 km/hr
Thus, man’s rate upstream = 4 km/hr
Man’s rate downstream = 8 km/hr
Rate of stream = ½ (8 – 4) = 2 km/hr

Method 2:
We have,
Up rate + down rate = 2 * rate in still water
= 2 * 6 = 12 km/hr
Also, up rate: down rate = 1:2
So, dividing 12 in in the ration of 1: 2, we get
Up rate = 4 km/hr
Down rate = 8 km/hr
Rate of stream = 8 – 4 / 2
= 2 km/hr
Method 3 (shortest Method): let the rate of stream = x km/hr
Then,
 6 + x = 2 (6-x)
Or, 3x = 6
X = 6/3 = 2 km/h
Theorem 2: for boats and streams:
A man can row x km/hr in still water. If in a stream which is following at y km/hr, it takes him z hrs to row to a place and back, the distance between the two places is z(x2 – y2 ) / 2x
Proof: man’s speed up stream = (x – y) km/hr
Man’s speed downstream = (x + y ) km/hr
Let the required distance be ‘A’ km then
BOATS AND STREAMS QUANTITATIVE APTITUDE STUDY NOTES

Or, 2Ax / x2 – y2 = z
The required distance = z(x2 – y2) / 2x

Ex. 4: A man can row 6 km/hr in still water. When the river is running at 1.2 km/hr, it takes him 1 hour to row to a place and back. How far is the place?
Solution: Man’s rate downstream = (6 + 1.2) km/hr = 7.2 km/hr
Man’s rate upstream = (6 – 1.2) km/hr = 4.8 km/hr
Let the required distance be x km. Then
x/7.2 + x/4.8 = 1
or 4.8x + 7.2x = 7.2 * 4.8
x = 7.2 * 4.8 / 12
= 2.88 km.
By direct formula: required distance = 1*(62 – (1.2)2) / 2*6
36 – 1.44 / 12
3 – 0.12
=2.88 km.
Theorem 3: for boats and streams:
A man rows a certain distance downstream in x hours and returns the same distance in y hrs. If the stream follows at the rate of z km/hr then the speed of the man  in still water is given by
Z(x+y) / y-x km/hr.

Proof: let the speed of the man in still water be ‘m’ km/hr.
Then, his upstream speed = (m - z) km/hr.
And downstream speed = (m + z) km/hr/
Now, we are given that up and down journey are equal, therefore x(m + z) = y(m – z)
Or, m(y-x) = z(x+y)
M = z(x + y) / y – x km/hr
Ex. 5: Ramesh can row a certain distance downstream in 6 hours and return the same distance in 9 hours. If the stream flows at the rate of 3 km per hour, find the speed of Ramesh in still water.
Solution:
By the above formula: Ramesh’s speed in still water = 3(9+6) / 9-6 km/hr.
