There
are some shortcuts to solve the problem. Don’t get confused between the similar
types of questions, understand the question and remember the formulas. Some
important examples are given below:

**Example**: Anil, priyanka and Suresh together can complete a work in 20 minutes If Anil and priyanka together same work complete in 60 minutes, how many time required Suresh alone can complete that work?

**Answer**

**:**1 / 20 – 1 / 60 = 30 minutes.

**Example**: P completes a work in 12 days and Q completes the same work in 16 days. Find required time to complete the same work together.

**Answer**: Complete work in 1 day of P is 1 / 12

Complete
work in 1 day of Q is 1 / 16

Together
complete work P + Q in 1 day 1 / 12 + 1 / 16 = 7 / 48

Together
complete work 48 / 7 days

__How to Prepare for Maths Exam__**Example**: A, B and C together can finish a work in 50 minutes, A and B together finish the same work in 60 minutes. In how many minutes can C alone finish that work?

**Answer**: (1 / 50 – 1 / 60) = 300 minutes.

**Example**: A can do a piece of work in 12 days and B can do a piece of work in 4 days. Find how many days they working together to complete that work?

**Answer**: A 1 day work = 1 / 12

B 1
day work = 1 / 4

(1
/ 12 + 1 / 4) = 4 / 12 = 1 / 3

They
working together to complete that work in 3 days.

**Example**: A, B and C can complete a work together in 60 minutes. A and B can complete the similar work in 80 minutes. How much minutes can C take alone to complete that work?

**Answer**: C alone take = 1 / 60 – 1 / 80 = 240 minutes.

**Example**: 22 boys complete a piece of work in 32 days. In how many days will16 boys can complete that work?

**Answer**: 22 x 32 = 16 x d2

d2
= 22 x 32 / 16 = 44

So,
In 44 days 16 man can complete that work.

Take a Test Now |

**Example**: 20 labours can do piece of work in 30 days, then how many days 15 labour can complete double of the work?

**Answer**: 20 labours can do a piece of work in 30 days and now we need to find the double of the work by 15 labours.

We
use

=
(labour X working days) = (labour X working days)

=
20 x 30 = 15 x ?

=
600 = 15 x ?

=
600 / 15 = 40

Now
we need to double the working days is 40 x 2 = 80 days.

__Practice Which Helps In Preparation__**Example**: Subir and kabir can do a piece of work in 20 days and 12 days respectively. Subir started the work alone and then after 4 days kabir joined him till the completion of the work. How long did the work last?

**Answer**: Step 1: In 4 days subir work done = 1 x 4 / 20 = 1 / 5. Remaining work is = (1 – 1 / 5) = 4 / 5.

Step
2: Now subir and kabir work done by 1 day= (1 / 20 + 1 / 12) = 2 / 15.

Step
3: 4 / 5 work will be done by subir and kabir = (15 / 2 x 4 / 5) = 6 days.

So,
the total time taken = (6 + 4) = 10 days.

**Example**: Rajib and Rajesh together can complete a piece of work in 4 days. If Rajib alone can complete the same work in 12 days, in how long days can Rajesh alone complete that work?

**Answer**: Rajib and Rajesh can do piece of work 4 days, then

First
we find required 1 day time and work,

(Rajib
+ Rajesh) can do piece of work in 1 day’s = 1 / 4, Rajib 1 day’s work = 1 / 12.

Same
work Rajesh can do in 1 day’s = (1 / 4 – 1 / 12) = 1 / 6.

So,
Rajesh can alone complete the work in 6 days.

**Answer**: 25 Women can complete a work in 15 days, Women1 x working days1 = Women2 x working days 2

25
x 15 = Women2 x 5

Women 2
= 375 / 5 = 75

More
women need for complete this work (75 – 25) = 50.

**Example**: 8 boys can complete a piece of work in 40 hours. In how many hours will 20 boys complete that same piece of work?
