Time and Work shortcuts/ Tricks-Model3-(3people)

#### 1.A,B and C can complete a work in 2 days. If A  does the job alone in 6 days and B in 5 days. How long will it take for C to finish the job alone?

Ans)
A+B+C=2                           C=?
A           =6
B           =5

Now  Take the LCM of ((A+B+C) and A and B) then we get Total units of work
So   LCM of ((A+B+C) and A and B) = 30 units

• Now (A+B+C)'s one days work = 30/2
= 15 units per day
• Now A's one days work              = 30/6
= 5 units per day
• Now B's one days work              = 30/5
= 6 units per day
• Now C=(A+B+C)-A-B                = 15-5-6
C's one days work               = 4 units per day

• Now Total Days required for C  = Total No.of units/C's one days work
= 30/4
=7.5 days(15/2)

## Time and Work Shortcuts/Tricks

#### Time and Work- Model-2(Days based)

If you are confused on this please read first post then you will get clarification on this

#### 1.A can do a piece of Work in X days and B can do the same work in 3X days. To finish the work together they take 12 days. Then what is the value of X?

Ans)

A=X     days                    X=?
B=3X   days
A+B=12 days

Take the LCM of A and B(Total units)
=3X

• Let us find the A's one days's Work = (3X/X)   =3units/day
•                          B's one days's Work = (3X/3X)   =1units/day

Now A+B's one day's Work= 3+1
= 4 units/day

• Now the value of X=(Total units/(A+B)'s one day's work)
=3X/4
X=4/3

## what is Latitude, Longitude,Local Time (LT) and Time Zones?

#### Latitude and Longitude

Any location on Earth is described by two
numbers -its latilude and its longitude
Latitude
On a globe of the Earth, lines of latitude are
circles of different size. The longest is the equaton
whose latitude is zero, while at the poles at
latitudes 90 north and 90 south (or -909) the
circles shrink to a point
Longitude
On the globe, lines of constant longitude
(meridians') extend from pole to pole
Every meridian must cross the equator Since the equator is a circle, we can
divide it-like any circle-into 360 degrees, and the longitude of a point is then the
marked value of that division where its meridian meets the equator
For historical reasons, the longitude (meridian) passing the old Royal
Astronomical Observatory in Greenwich, England, is the one chosen as zero
longitude. Located at the eastern edgeof London, the British capital, the observatory
is now a public museum and a brass bandstretching across its yard marks the 'prime
meridian

A line of longitude is also called a meridian, derived from the Latin, from
meri, a variation of 'medius which denotes middle, and diem, meaning day
The word once meant "noon, and times of the day before noon were known as
ante meridian, while times after it were 'post meridian, Today's abbreviations
am.and pm come from these terms and the Sun at noon was said to be pasing
meridian" All points on the same line of longitude experienced noon (and any
other hour) at the same time and were therefore sald to be on the same "meridiÃ¡n

#### Local Time (LT) and Time Zones

Two important concepts,related to latitude and (especially)longitude are Local
Time (LI) and Universal Time (UT)
·Longitudes are measured from zero to 180" east and 180° west (or-180°), and
both 180- degree longitudes share the same line, in the middle of the Pacific Ocean
As the Earth rotates around its axis, at any moment one line of longitude "the
n meridian" faces the Sun, and at that moment, it will be noon everywhere on it.
After 24 hours the Earth has undergone a full rotation with respect to the Sun, and
Tc same meridian again faces noon. Thus each hour the Earth rotaten by 360/24-
The Date Line and Universal Time (UD

## Time and Work FOR SSC,UPSC,APPSC for all govt Exams

Time and work Problems can be solved in Two ways

• Percentage Method
• LCM Method
LCM method is easier to use so will practice by LCM method

### Model-1

#### 1.A alone can finish work in 12 days and B alone can finish the same work in 24 days. then in how many days can A and B together will finish same Work?

Ans)

A=12 days                                                       A+B=?
B=24 days

Now take the LCM of A and B because we need find out A+B
So LCM of A and B is =24 it means Total work is 24 Units

Now we can find one days work for A and B Seperately

#### A=(Total number of units/No of Days)

=(24/12)
=2 units/day

#### B=(Total number of units/No of Days)

=(12/12)
= 1 Unit/day

So that A+B's One day's Work= 2+1
=3 units / Day
•           A and B together will finish same Work=(Total no.of Units/(No.of units/day))
=24/3
=  8 Days required to complete same job

#### 2.A and B can do a piece of Work in 12 days. While B alone can finish it in 30 days then A alone finish the work in?

Ans)

A+B=12 days                                                       A=?
B=30 days

Now take the LCM of (A+B) and B because we need find out A
So LCM of A and B is =24 it means Total work is 60 Units

Now we can find one days work for (A+B) and B Seperately

#### A+B=(Total number of units/No of Days)

=(60/12)
=5 units/day

#### B=(Total number of units/No of Days)

=(60/30)
= 2 Unit/day

So that B's One day's Work= ((A+B)'s work-A's Work)  = (5-3)
=3 units / Day
•          B alone can finish same Work=(Total no.of Units/(No.of units/day))
=60/3
=  20 Days required to complete same job

## The Indus Valley Civilization

The Indus Valley Civilization
The History of India begins with the birth of the Indus Valley Civilization, more precisely known as Harappan Civilization. It flourished around 2,500 BC, in the western part of South Asia, what today is Pakistan and Western India. The Indus Valley was home to the largest of the four ancient urban civilizations of Egypt, Mesopotamia, India and China. Nothing was known about this civilization till 1920s when the Archaeological Department of India carried out excavations in the Indus valley wherein the ruins of the two old cities, viz. Mohenjodaro and Harappa were unearthed. The ruins of buildings and other things like household articles, weapons of war, gold and silver ornaments, seals, toys, pottery wares, etc., show that some four to five thousand years ago a highly developed Civilization flourished in this region.
The Indus valley civilization was basically an urban civilization and the people lived in well-planned and well-built towns, which were also the centers for trade. The ruins of Mohenjodaro and Harappa show that these were magnificent merchant cities-well planned, scientifically laid, and well looked after. They had wide roads and a well-developed drainage system. The houses were made of baked bricks and had two or more storeys.
The highly civilized Harappans knew the art of growing cereals, and wheat and barley constituted their staple food. They consumed vegetables and fruits and ate mutton, pork and eggs as well. Evidences also show that they wore cotton as well as woollen garments. By 1500 BC, the Harappan culture came to an end. Among various causes ascribed to the decay of Indus Valley Civilization are the recurrent floods and other natural causes like earthquake, etc.

### Vedic Civilization

The Vedic civilization is the earliest civilization in the history of ancient India. It is named after the Vedas, the early literature of the Hindu people. The Vedic Civilization flourished along the river Saraswati, in a region that now consists of the modern Indian states of Haryana and Punjab. Vedic is synonymous with Hinduism, which is another name for religious and spiritual thought that has evolved from the Vedas.
The Ramayana and Mahabharata were the two great epics of this period.

## Identify the Reasons for Fear of Interviews:

The fears need to be overcome early so that these measures do not become a habit for anyone. For this, it is essential that you have to understand what exactly causes the fear of job interviews

### 1. Lack of preparation:

If you go for an interview without being completely prepared, you are little bit disturbance to have fears. It is the fear of being asked questions for which you are not prepared. This uncertainty usually nags the minds of individuals and prevents them from concentrating on what they know. It also develops measures and body language that have a negative impact on the minds of the interviewers.

### 2. Fear of not getting the job:

Many job seekers look for a good and well paying job because they have to support their family. The burden of that responsibility makes them need the job desperately. They always thought that what will happen if they don’t get the job. The constant worry at the back of the mind causes fear and this affects to they didn't perform well. They worried if they fail to get a  job. The worry reframes itself into underlying fear of not getting the job. So everyone need to overcome it.

### 3. Fear of facing an interviewer:

There are many individuals who fear to face someone eye to eye. When they have to confront an interviewer face to face, they shy away and avoid situations like this. Even shy and individuals have to go through the ordeal of facing a job interview and they cannot escape it. The fear of facing an interviewer reveals itself through lack of eye contact and excessive nervousness. Such individuals lose out on best paying opportunities because of their shyness. So everyone can overcome this.

### 4. Lack of confidence in oneself:

An individual’s life, childhood and upbringing are responsible for his self  and confidence in himself. Individuals who are brought up in a strict and conservative environment usually lack confidence of his/her. Lack of confidence is visible in an individual when he grows up. He may have drooping shoulders and lack of eye contact with individuals if he/she is not confident. Lack of confidence may affect an individual’s career in a very big manner.

### 5. History of the previous jobs:

Very few people are blessed with stable careers in the present generation. Individuals frequently changing their jobs and you never get to see people stay in the same job for 20-30 years. In such a situation, individuals who lose their jobs due to lack of performance  and also lose their confidence in themselves. The insecurities of a volatile job life makes him scared and nervous. This fear gets visible during the future interviews. It prevents him from making a good impression during interviews.

## Number series/simplification short tricks/shortcuts-Part-1 for all government exam preparation

Number series/simplification short tricks/shortcuts-Part-1 for all government exam preparation:-
First of all we need to know the basics of Divisibility rules before the preparation of Shortcuts.

Divisiblity rules has been devided in to Four categeries as per their similarity

• 2,4,8
• 3,9
• 5,10
• 11
Divisibility rules by First category

Divisibility rule by 2:-

2*1=2, so that we consider last digit
If the last digit of the number is divisible by 2 then the Whole number will be divisible by 2

Example:-1)24286476/2

Ans) (6/2)=3  so that 24286476 is Divisible by 2

## Number series/simplification short tricks/shortcuts-Part-2 for all government exam preparation

Divisibility rules by Third category(5,10):-

Divisibility rule by 5:-

If the last digit of the number contains 0 or 5 then only the number divisible by 5

#### Example: 54625860/5

In above question, the last digit of the number is 0 So that the number(54625860) is divisible by 5.

Divisibility rule by 10:-

If the last digit of the number contains 0 then only the number divisible by 10

#### Example: 14526380/5

In above question, the last digit of the number is 0 So that the number(14526380) is divisible by 10.

Divisibility rules by Fouth category(11):-

In this we need to first start counting from the right side after that we do the subtraction of Sum of numbers in Odd places-Sum of numbers in Even place then we get some result. If the result divisible by 11 then the whole number will be divisible by 11

Example:  142318/11

Result= (Sum of numbers in Odd places-Sum of numbers in Even place)/11
(8+3+4)-(1+2+1)
=11/11
=1

In the above Question 142318 is divisible by 11 then the whole number is divisible by 11.
