Shortcut Tricks are very important things in competitive exam. Time takes a huge part in competitive exams. If you know how to manage time then you will surely do great in your exam. Most of us miss that part. Few examples on time and work shortcuts is given in this page below. All tricks on time and work are provided here. We request all visitors to read all examples carefully. You can understand shortcut tricks on Time and Work by these examples.

First of all do a practice set on math of any exam. Choose any twenty math problems and write it down on a page. Do first ten maths using basic formula of this math topic. You also need to keep track of the time. After finish write down total time taken by you to solve those ten maths. Now practice our shortcut tricks on time and work and read examples carefully. After this do remaining ten questions and apply shortcut formula on those math problems. Again keep track of timing. This time you will surely see improvement in your timing. But this is not all you need. You need more practice to improve your timing more.

You all know that math portion is very much important in competitive exams. That doesn’t mean that other sections are not so important. But only math portion can leads you to a good score. A good score comes with practice and practice. All you need to do is to do math problems correctly within time, and you can do this only by using shortcut tricks. But it doesn’t mean that you can’t do math problems without using any shortcut tricks. You may have that potential that you may do maths within time without using any shortcut tricks. But so many people can’t do this. Here we prepared time and work shortcut tricks for those people. We try our level best to put together all types of shortcut methods here. But we may miss few of them. If you know anything else rather than this please do share with us. Your little help will help others.

Time and Work Examples 4

Some important facts are needed for Time and work Problems. Here is some examples of this chapter related are given. Such that a person do a piece of work which has to be require more time to complete why because capacity is limited to that person but two or more person do the same piece of work which require less time and effort.

This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam. Under below given some more example for your better practice.

Example #1

2 men can complete a single work in 3 days. 2 women can complete the same work in 9 days and 3 boys can complete the same work in 8 days. In 1 day 3 women and 4 boys together finished a portion of work. If only men were finish the remaining work in 1 day, find the number of total men would be required.

- 4
- 6
- 8
- 12

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (A)

**How to Solve**

If 2 women completed the work in 9 days,

Then, days required for 3 women is

2 x 9 / 3

= 6 days.

If 3 boys complete the work in 8 days,

Then, days required for 4 boys is

3 x 8 / 4

= 6 days.

So, work done by 3 women and 4 boy in 1 day is

(1 / 6) + (1 / 6)

= 1 / 3.

So, remaining work is

1 – (1 / 3)

= 2 / 3.

So, in to complete the work in 1 day, the required men is

2 x 2 x 3 / 3

= 4

Example #2

A can do a piece of work in 12 days and B can do the same piece of work in 6 days. Find days required to complete that work together.

- 3 Days
- 4 Days
- 6 Days
- 9 Days

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (B)

**How to Solve**

A’s 1 day of work is 1 / 12.

B’s 1 day of work is 1 / 6.

Together they need

(1 / 12) + (1 / 6)

= 1 / 4

= 4 days.

Example #3

Anita, Ajay and Kunal can complete a work together in 40 minutes. Anita and Ajay together can complete the same work in 60 minutes. Find the time required for Kunal alone to complete that work.

- 80 Minutes
- 100 Minutes
- 110 Minutes
- 120 Minutes

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (D)

**How to Solve**

Anita + Ajay + Kunal 1 minute work is 1 / 40.

So, Kunal alone can complete the task in

(1 / 40) – (1 / 60)

= 1 / 120

= 120 minutes.

Example #4

24 women complete a piece of work in 16 days. How many more women needed to be hired to complete the work in 12 days.

- 22 Women
- 28 Women
- 32 Women
- 36 Women

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (C)

**How to Solve**

W = women, D = Day.

W1 x D1 = W2 x D2

24 x 16 = W2 x 12

W2 = 384 / 12

W2 = 32

Example #5

8 women can complete a work in 36 hours. In how many hours will 24 women complete that work?

- 10 Hours
- 12 Hours
- 14 Hours
- 16 Hours

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (B)

**How to Solve**

Women x Hours = Women x ?

8 x 36 = 24 x ?

288 = 24 x ?

? = 288 / 24

? = 12 hours.

Example #6

20 boys are required to complete a work in 100 days. How many boys are required to complete that work in 5 days?

- 200 Boys
- 250 Boys
- 300 Boys
- 400 Boys

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (D)

**How to Solve**

Boys1 x Days1 = Boys2 x Days2

20 x 100 = ? x 5

? = (20 x 100) / 5

? = 400.

So, 400 boys will require to complete that work in 5 days.

Example #7

The work of ratio Amit and Bikash is 3 : 5. If Amit complete a work in 10 days. In how many days the work can be completed by Bikash?

- 5 Days
- 6 Days
- 8 Days
- 10 Days

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (B)

**How to Solve**

Amit : Bikash = 3 : 5

Amit = 10 days

Bikash = ?

Amit = 10 x 3 = 30 work

Bikash = 30 / 5 = 6 days

**Rough Workspace**

Example #8

A work of painting a wall is done by Amit and Bikash at the ratio of 3 : 5. If Amit and Bikash together did that work in 30 days. How many days will required for Bikash alone do that work?

- 90 Days
- 100 Days
- 110 Days
- 120 Days

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (A)

**How to Solve**

We know that, the ratio of Amit and Bikash is 3 : 5.

Amit + Bikash together did that work in 30 days.

So, Amit + Bikash = 30 x 15 = 450 work.

Bikash alone can do it in = 450 / 5 = 90 days.

its a very good technique to solve the question easily and i have supported for competetive exam face

very simple technique

wrong techniq

great work guys..!!

very simple technique

i think some thing is wrong in example 2

how can this question be solved?

Arjun completed a work in 35 days and biju in 45 days. if together they complete it and get a payment of Rs 3200, what is biju’s share?

Find the ratio of their work done in 1 day first.

Arjun’s 1 day work : 1/35

Biju’s 1 day work : 1/45

Ratio is : Arjun : Biju = 1/35 : 1/45 = 9:7

Total Payment is : 3200.. Total Ratio is 16..

So, Arjun’s share = (9/16)*3200 = Rs. 1800

And Biju’s share = (7/16)*3200 = Rs. 1400.

Or simply 3200-1800 = 1400…

Why ratio become 9:7 instead of 7:9?

Please guide me…

Because ratio of capicty is iopposite ratio of efficiency

simple ratio both of 7:9 than total 16, 9/16*3200=1800 than 3200-1800=1400

Biju share is 1800

1800

biju =45(3200/(45+45))

45*3200/80

1800

(

Wages are distributed in the ratio of efficiency or work done in a day. In this case efficiency is 9:7

3200*7/16=1400

Wages are divided in the inverse ratio of number of days.

ie. 45:35 or 9:7

7/16 x 3200 = 1400

very techniqe method

What’s the method and answ for this question If 4 men and 6 women can do a piece of work in 12 days working 7 hrs a day, how many days will it take to cmplte a work twice as large with 10 men and 3 women working together 8 hrs a day?

21/6

16.8 days

If a,b,c together take 6 hr less than a, 1hr less than b, 1/2 hr less than c alone to finish job , then how much time a& b together complete the Jo b
