Example #1 – Time and Work Math Example

P, Q and R can complete a piece of work in 8, 12 and 24 days respectively. How many days will required to complete the same work if they work together.

4 Days

6 Days

10 Days

16 Days

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (A)

How to Solve P’s 1 day work = 1 / 8 Q’s 1 day work = 1 / 12 R’s 1 day work = 1 / 24 So, together they need, (1 / 8) + (1 / 12) + (1 / 24) or, (3 + 2 + 1) / 24 or, 1 / 4 = 4 days.

So, they need 4 days to complete the work if they work together.

Example #2 – Time and Work Math Example

4 boys and 6 girls can complete a piece of work in 8 days while 3 boys and 7 girls can complete the same piece of work in 10 days. Find the required days needed for 10 girl to complete that work.

18 Days

25 Days

40 Days

50 Days

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (C)

How to Solve Let, 1 boy’s 1 day’s work = X. Let, 1 girl’s 1 day’s work = Y.

Then, 4X + 6Y = 1 / 8 And, 3X + 7Y = 1 / 10

By solving of two equations, We get Y = 1 / 400 and X = 11 / 400.

So, 1 girl’s 1 day’s work = 1 / 400. Then 10 girl’s 1 day’s work = (1 x 10 / 400) = 1/40.

So, 10 girl will complete the work in 40 days.

Example #3 – Time and Work Math Example

John painted a wall in 3 days of 12 hours each and Paul can do it in 3 days of 8 hours each. How long will they take to do it, working together 12 / 5 hours a day?

4 Days

6 Days

7 Days

12 Days

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (B)

How to Solve John finished the work in ( 3 x 12 ) = 36 hours. Paul finished the work in ( 3 x 8 ) = 24 hours.

So, John’s 1 hour work = 1 / 36 And, Paul’s 1 hour work = 1 / 24 Together their 1 hour work = ( 1 / 36 ) + ( 1 / 24 ) = 5 / 72 hours.

So, both finished the work in 72 / 5 hours. Or, ( 72 / 5 ) X ( 5 / 12) = 6 days.

So, they need 6 days to complete the work if they work together.

Example #4 – Time and Work Math Example

Ram and Shyam can do a piece of work in 30 days. They work together in 20 days and then Shyam left. After another 20 days Ram finish the remaining work. In how many days Ram can alone finish the work?

35 Days

45 Days

50 Days

60 Days

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (D)

How to Solve Ram and Shyam together 1 day work is 1 / 30. So, their 20 days work = ( 1 x 20 / 30 ) = 2 / 3.

Remaining work = 1 – ( 2 / 3 ) = 1 /3.

Now, 1 / 3 work done by Ram in 20 days. So, the whole work done by Ram is 20 / (1 / 3) or, 20 x 3 = 60 days.

Example #6

P and Q can do a piece of work in 45 days and 40 days respectively. They began the work together. But P left after some time and Q finished the remaining work in 23 days. After how many days did P leave?

5 Days

7 Days

9 Days

11 Days

Show AnswerShow How to SolveShow Shortcut TricksOpen Rough Workspace

Answer: Option (C)

How to Solve Q works alone for 23 days. So, Work done by Q in 23 days = 23 / 40 work. So, P + Q do together ( 1 – 23 / 40 ) = 17 / 40. Then , P + Q do this work in 1 day ( 40 x 45 / 40 + 45 ) = 40 x 45 / 85 days.

So, P + Q together do the work in = ( 40 x 45 / 85 ) x 17 / 40 = 9 days.

Shortcut Tricks We can ignore middle steps then perform direct formula 40 x 45 / 40+ 45 ( 40 – 23 / 40 ) = 9 days.

Example #9

P and Q can complete a work in 15 days and 10 days respectively. They began doing the work together. But, after 2 days Q had to leave and P alone complete the remaining work. So, in how many days the whole work was completed?

7 Days

10 Days

12 Days

15 Days

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (C)

How to Solve (P + Q)’s 1 days work = ( 1 / 15 ) + ( 1 / 10 ) = 1 / 6.

So, work done by P and Q in 2 days = ( 1/6 x 2) = 1 / 3.

Then, remaining work is (1 – 1/ 3) = 2 / 3.

Now, P’s 1 day of work is 1 / 15. So, remaining 2/3 work will be done by P in (2/3) / (1/15) or, (2/3) X 15 = 10 days.

Hence, total time taken to finished the work is (10 + 2) = 12 days.

VERY HELPFULL THANK U

A and B together can do a piece of work in 5 hours,A and C together can do the same piece of in 4 hours,, B and C together can do the same work in 7/2 hours. How many hours A can alone do the same work ?

y 40 x 45/45+40

A+B= 1/5,B+C=2/7,C+A=1/4

2(A+B+C)=1/5+2/7+1/4

=28+40+35 /140

=103/140

A+B+C= 103/280

A alone can do same work = A+B+C – B+C

= 103/280 – 2/7

=103 – 80 / 280

=23/280 days and in hours 280/23 can A alone do the same work…….

A and B both complete works in 16 days and B and C complete works in 24 days….if A is working 3 more time(3 guna) than C. Than how many days will take A,B and C for this work?? Plz reply a shortrick for this question

i didnt undersatnd the 4th example can u pls elaborate it again

First step is here p given. That is Q works alone for 23 days and proceed.

4 men and 6 women can complete a work in 8days, while 3 men and 7 women can complete it in 10 days.in how many days will 10 women complete it.

take look this example Let 1 boy’s 1 day’s work = x.

Let 1 girl’s 1 day’s work = y.

Then, 4x + 6y = 1 / 8

3x + 7y = 1 / 10

by solving of two equations,

we get y = 1 / 400 and x = 11 / 400

So, 1 girl’s 1 day’s work = 1 / 400.

Then 10 girl’s 1 day’s work = (1 x 10 / 400) = 1 / 40.

So 10 girl will complete the work in 40 days.

how can we gaet y=1/400 after solving the two equations . i am getting y=1/40 ..?

I couldn’t understand this step. Please explain.

Then 10 girl’s 1 day’s work = (1 x 10 / 400) = 1 / 40.
