@fedponek, gzl. others, shoot and lets all try solving them.
Tanks man. 4rm now on, I wil try to think b4 answering such a question.
seee.. things have changed ooh this kind of questions no longer show up in aptitude tests... they are way too cheap... u need to upgrade
@acason u r very correct...
U guys should try these...
Log2X - 5LogX + 6 = 0, what is x?
If 9 persons can do a piece of work in 12 days. Let solve it as slated bellow:
Let x denote the piece of job.
x job divided by 9 persons, was done in 12 days.(Mathematically;x/9 =12 days)
x = 9*12
x = 108.
108 / 9 = 12days
FOR 4 PERSONS:
108 / 4 = 28 days.Ans. 4 persons will finish the same job in 28 days.
FOR NUMBER OF PERSONS THAT WILL DO IT IN 3 DAYS:
108 / numbers of persons(y) = 3 days
3y(number of perrsons) =108
3y / 3 = 108 / 3
y (number of persons ) = 36 persons
Therefore 36 persons will finish the same job in 3 days.

saw dis question in chams apt test
Let me put a new dimension to this.... 8)
...Since the job has been completed by 9 persons,
then there will be no job for the other 4 persons to do
and nobody will be required to do the job since it's been completed! ;D ;D
4 people will finish the job in 27days while 36 people will finish it in 3days
@Dagunro, na true now .... ;D ;DQuote:

From your calculation,it is supposed to be 108/4 = 27days; not 28days.Quote:

LET P= PERSONS AND D = DAYYS.
THEN USE P1D1 = P2D2. MAKE D UNKNOWN (D2 IN THIS CASE) THE SUBJECT OF THE FORMULA AND THESE ARE D ANSWERS (27 & 36 respectively)
A snail climbs 3feet and drops 1foot per day in a 30 feet deep well.How long would it take the snail to come out of the well? Guys pls brainstorm!!!!!!
9persons=12days
4persons=xdays
9x=12*4
9x=48
x = 48/9
