Question

a wall can be built by 6 men working 8 hours a day in 5 days. How many days will it take 4 men to build the wall if they wrok only 5 hours a day

Answer 1

best idea is to figure out the rate per man and then multiply

Answer 2

more explanation pleease???

Answer 3

8 hours a day in five day is \(8\times 5=40\) hours
it takes 6 men 40 hours to do the job, therefore it takes each man \(6\times 40=120\) hours to do the job

Answer 4

and so each man's rate is \(\frac{1}{120}\) that is each man does one one hundred and twentieth of a job per hour

Answer 5

could u calculate the answer i have to make sure u r right...

Answer 6

now we want the number of days it takes 4 men working 5 hours a day. lets call the number of days it takes \(x\)
then \[4\times 5\times \frac{1}{120}\times x=1\] and solve for \(x\)

Answer 7

ur answer is wrong

Answer 8

the answer is 6 aaaaand its wrong

Answer 9

i think 0 is the answer as the wall is already built

Answer 10

please dont joke...

Answer 11

iam not joking take problem in physical context matter occupies space and has mass so you cannot make the wall again by just destroying it your question should have been a similar type of wall......or maybe the same dimensions of the wall................

Answer 12

this is math ......THIS IS PROPORTION...i think ur in the wrong study bro..

Answer 13

even if it is maths but u cannot exceed your practical limits...............

Answer 14

if u arent goin to answer leave it to someone else....

Answer 15

you got angry bro ......please dont mind man..........

Answer 16

leave the question now i need the help of another person...

Answer 17

Answer 18

i have the answer but dunno the method....... it is 12 days

Answer 19

leave now!

Answer 20

LEAVE U USELESS PEOPLE I NEED HELP U R DOIN NOTHIING

Answer 21

the procedure is mentioned below
time taken by 6men = 8*5=40hrs
work done by 6men= 1/40hrs
total work done = 1/(40*6)=1/240 (i)
let the 4men take xdays
total time taken by four men=5xhrs
work done = 1/5x
total work done =1/20x (ii)
hence from (i) and (ii)
1/20x=1/240
20x=240
x=12
hence they take 12 days

Answer 22

you get angry very early have patience ..............and above all be happpy...........

Answer 23

ho ho that is because i wrote \(6\times 40=120\) but in fact \(6\times 40=240\)

Answer 24

he he..............

Answer 25

\[4\times 5\times \frac{1}{240}\times x=1\]
\[x=\frac{240}{20}=12\] maybe that is the answer

Answer 26

ok, i am leaving now as requested

Answer 27

thats what i have solved above methodologically
