    This is merely a subtype of Time n Work problems. and can be solved using our good ol STDtable Method.

    1. Case 1: Women finish entire job2. Case 2: Women to finish remaining job3. Case: Child labour

    Case 1: Women nish entire job

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

    Suppose 1 man can pour 1 bucketful of water in the tank in 1 minute.If 6 men work together, they pour 6 buckets in a tank in 1 minute.In short, you multiply the speed with number of person.

    Our usual table

    1 Man 1 Woman 4 men & 6 women 3 men & 7 women

    Speed m w 4m+6w 3m+7w

    Time 8 10

    [Aptitude] Time n Work: 4 men and 6 women can complete a work in 8Days then

  • distance

    Distance covered in each column is same.So compare last two columnsDistance = distanceSpeed x time = speed x time(4m+6w)*8=(3m+7w)*10

    Solve this equation and you get m=11wReplace this value of w in last column

    1 Man 1 Woman 4 men & 6 women 3 men & 7 women

    Speed m w 4m+6w 3(11w)+7w

    Time 8 10

    distance

    3(11w)+7w=33w+7w=40w

    1 Man 1 Woman 4 men & 6 women 3 men & 7 women

    Speed m w 4m+6w 40w

    Time 8 10

    distance 40w x 10= 400w

    So the total work isSpeed x time = distance40w x 10= 400w

    If 10 women work together, theyve to cover 400w kms. Make a new column, run STD formula

  • 1 Man 1 Woman 4 men & 6 women 3 men & 7 women 10 women

    Speed m w 4m+6w 40w 10w

    Time 8 10 ??

    distance 40w x 10= 400w 400w

    10w x time =400wTime =400w/ 10w=40days.

    Answer: If 10 women work together, itll take 40 days to finish the job.

    Case 2: Women to nish remaining job

    12 men can complete a piece of work in 4 days, while 15women can complete the same work in 4 days. 6 men startworking on the job and after working for 2 days, all of themstopped working. How many women should be put on thejob to complete the remaining work, if it is to be completedin 3 days?

    12 Man 15 Woman

    Speed 12m 15w

    Time 4 4

    distance

    Distance covered in both column is same so compare them

  • Speed x time = speed x time12m x 4= 15w x 44m=5wM=(5/4)w

    The question is asking about number of women in the end, so better convert everything interms of women.Given: 6 men start working on the job and after working for 2 days, all of them stoppedworkingMake a new column.

    12 Man 15 Woman 6men

    Speed 12m 15w 6x (5/4)w

    Time 4 4 2

    distance 60w 6x (5/4)w x2=15w

    As you can see, Ive applied STD formula in last two columns to find distance simultaneously.Remaining work=60w minus 15w=45wRequired: we want to finish this work in 3 days.Asked: How many women should be put on the job to complete the remaining work, if it is tobe completed in 3 days?

    Make a new column. Suppose we need F number of women so speed = f x w = Fw.

    12 Man 15 Woman 6men Find women

    Speed 12m 15w 6x (5/4)w Fw

    Time 4 4 2 3

    Distance 60w 15w 45w

  • Time limit is given to us: complete remaining work in three days. So t=3 for last column.Run STD on last columnFw x 3 =45wF=45w /3wF=15Answer : 15 women required.

    Important: Remaining work is to be completed in 3 days. So t=3If they had asked total work is to be completed in 3 days, well need to take t=1, because thosemen already worked for 2 days to only 1 day left to complete the job (2+1=3 days)

    Case: Child labour

    Twelve children take sixteen days to complete a work whichcan be completed by eight adults in twelve days. Sixteenadults started working and after three days ten adults leftand four children joined them. How many days will theytake to complete the remaining work?

    12 kids 8 men

    Speed 12k 8m

    Time 16 12

    Distance

    Since work done in both columns is sameSpeed x time = speed x time12k x 16= 8m x 12K=(1/2)m

  • Concentrate on middle column (8 men) run STD table on it. You get distance = 8m x 12 =96mSo total distance to be covered is 48m

    Given: Sixteen adults started working and after three days .Means 16 men worked for 3 days.

    12 kids 8 men 16 men

    Speed 12k 8m 16m

    Time 16 12 3

    Distance 8m x 12=96m 16m x 3=48m

    Weve run STD on last column and got that 16 men covered 48m kms.So remaining work is 96m minus 48m=48m

    Given: after three days ten adults left and four children joined themSo now men left =16 minus 10 =6 men and 4 kids joins them so speed is 6m+4kMake a new column

    12 kids 8 men 16 men Men & kids

    Speed 12k 8m 16m 6m+4k

    Time 16 12 3 ??

    Distance 96m 48m 48m

    Run STD on last column(6m+4k) x time =48mBut We already calculated that K=(1/2)mApply it in above equation{6m+4(1/2)m} x time =48m{6m+2m} x time = 48m8m x time = 48mTime =48m /8mTime=6 days.

    diptanshu gaurhey sunny 24 is the correct answer actually i use a differentmethod for time & work questions acc. to my method 24 menfinish the job in 16 days and 32 women did it in 24 days first takelcm of 16 and 24 as their respective speed to do the work ie: 48 (let48 as total work that needs to be done) if we divide 48 by 16 then itis 3 thats the speed of 24 men in a day n same for women 2 is thespeed now what will be the speed of 16 men that will be 2 because24 and 16 divisible by 8 so speed of 8 men will be 1 16=2 & 24=3same for women speed will be 16=1. the work has to be finishedwithin 14 days if 16 men work for 14 days the total work done bythem will be 28 becoz speed is 2 & women will do 14 work becozspeed is 1 now total work done=42 remaining 6 that is to be doneso if 24 men can do 3 work in one day they will do 6 in two days sothe remaining 6 they will contribute after 6 days. question is askinghow main additional men required as well as other will also workfor 2 days thankyou.

    SANDHYAhii Sunny,

  • in the last sentence of ur qn is how many men more to be added tocomplete the work. It means 24 men is already working, how manymore men should be added

    So, its (24M+X) men has to do 96M work in 2 daysso 24M+X = 96M/224M+X=48MX=48M-24Mi.e, x=24 men more needed to work

    R E P L Y ( / 2 0 1 2 / 0 5 / A P T I T U D E - T I M E - N - W O R K - 4 - M E N - A N D - 6 - W O M E N . H T M L ?R E P L Y T O C O M = 2 1 7 8 8 3 # R E S P O N D )

    AanyaCorrect ans 24.1 mans 1 day work =1/16*24, for woman its 1/32*2416 men 12 day work=16*12/16*24=1/216 women 12days work=16*12/32*24=1/4Total completed work in 12 days=3/4Rest work=1/416 men+ 16 women 1 day work= 16/16*24 + 16/32*24= 1/24+1/48=1/16Their 2 days work=1/8Extra men needed to complete the work=1/4-1/8= 1/8 in 2 days means1/16 in one day24 men can complete a work in 16 days means their 1 day work 1/16, sowe need 24 men.

    In writing it seems long but very quick when we actually solve!

    R E P L Y ( / 2 0 1 2 / 0 5 / A P T I T U D E - T I M E - N - W O R K - 4 - M E N - A N D - 6 - W O M E N . H T M L ?R E P L Y T O C O M = 2 1 7 8 8 5 # R E S P O N D )

  • 24*16=32*24i.e.1M=2F

    so,16M+16F=24Mfind remaining worki.e 1- (12/16)=1/4th work remainsnowwork- 1/4men- 24days- 2

    use relation WMT

    Ans is 24 men

    R E P L Y ( / 2 0 1 2 / 0 5 / A P T I T U D E - T I M E - N - W O R K - 4 - M E N - A N D - 6 - W O M E N . H T M L ?R E P L Y T O C O M = 2 1 7 9 8 8 # R E S P O N D )

    sunny kumarThanks Sankalp!But could you plz help me with my solution given below-

    after M=2F OR F=M/2So, 8M + 16M24M *12 = 288M- Work done by 16M + 16FWork left to be done= (16*24M)- 288M= 96M

  • Here on wards am facing the problem-as if 1M can do M work per daythan to complete in two days why shouldnt it be 48M?

    Sorry friend my typing mistakesAns is 48..If u see my processUr ans is right.
