Tricks to solve Time and Work problems :

Some Important Formula:
Time taken single piece of work, If A Person do a piece of work or job in n days, then person’s finish the work in n days = 1 / n.

A person do a piece of work in 1 days = 1 / n, then person can finish the work in n days.

If A person twice work a workman as B person, then Ratio of work done by A and B is = 2 : 1.

The reciprocal of day”s work gives the alone time i.e., alone time ( or time to complete a job by a single person) = 1 / 1 day”s work


when more then one person working on tha same type of work, then there combined work = sum of 1 day”s work by each person. suppose P, Q , R work same piece of work by each person (P + Q + R)”s 1 day’s work = P’s day’s work + Q’s day’s work + R’s day’s work.


Example 1:
20 labour can do piece of work in 30 days, then how many days 15 labour can complete double of the work ?
Answer:
20 labour can do a piece of work in 30 days and Now we need to find the double of the work by 15 labour.
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


Example 2:
22 boy complete a piece of work in 32 days . In how many days will 16 boy 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 .



Example 3:
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.and Remaining work is = ( 1 – 1 / 5 ) = 4 / 5.
Step 2: Now subir and kabir work done by 1 days = ( 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 4:
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 many days can Rajesh alone complete that work?
Answer :
Rajib and Rajesh can do piece of work 4 day’s, 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.
