WOW!

Answer 16

See, P painters takes 4 days to paint H houses.

So, P painters take 1 day to paint H/4 of a house.
1 painter paints therefore h/4p of a house.

Now 6 painters in 2 days will paint = h/4p*6*2
Thus it is the option D.

Answer 17

dang arnab is fast

Answer 19

So, you all are SAT guys...?

Answer 20

I'm a 7th grader, just took my first ACT.

Answer 21

@Arnab_Chatterjee ; Yes im giving SAT.

I dont get this part:
1 painter paints therefore h/4p of a house.

Answer 22

Saif is the SAT guy hhaa

Answer 23

@satellite73 , can you help me understand? :S

Answer 24

See, @saifoo.khan , if p painters can in 4 days paint h houses..
Thus in I day, p no. of painters paints h/4 houses. (Their work will be limited due to less time).
Again if from p no. of painters, we keep only 1 of them, so he will be able to do only h/4 part of a house divided by the number of p painters who all used to paint h/4 houses in 1 day. Thus 1 painter can paint in 1 day - h/4p houses.. I hope you got it...

Answer 25

@saifoo.khan , did you get it?

Answer 26

@Arnab_Chatterjee , try to..

Answer 27

trying*

Answer 28

Is the answer C or D?

Answer 29

Its D

Answer 30

I got C.

Answer 31

@arnab
I do understand h/4 thing.. But not after that. Sorry

@Zeerak : D is the correct one.

Answer 32

zee i got C at first too then retried for D

Answer 33

idea is what @Arnab_Chatterjee said, convert everything to unit rate
if it is confusing, try replacing P by an actual number, but an ugly one like 13 that does not reduce
then see what you would do to solve, then go back and replace 13 by P

Answer 34

Ok.
A very simple example.
2 ants in 4 days can eat 8 biscuits...
You order the ants to eat as much as they can.. in one day..
So, 2 ants in 1 day can eat only 2 biscuits ( which is 8/4)..
Again you tell one ant to go away...
And tell the other one to eat as much as he can in 1 day..
So, 2 ants could eat 2 biscuits in a day..
1 ant gone.. therefore he can only eat 1 biscuit a day.. (Thus, 8/(4*2))..

Same rule applies to the SAT question.

Answer 35

@satellite73 , I think this is the best example.. :)

Answer 36

@saifoo.khan , are you clear now..?

Answer 37

Here too, i got till 8/4 but not after that. :/

Answer 38

8/4=2 saif:)

Answer 39

OMG! Thanks @karatechopper
I thought: 8/4 = 2/1

Answer 40

OMG IKR!

Answer 41

The problem is...
It is. <-- PERIOD!

Answer 42

For what it is worth:
P people working for d days do p*d amount of work
the number of houses built per that amount of work is h, so we have a ratio
h/pd = houses/amount of work. for this problem d=4, so the rate is
h/4p

now given an amount of work= 6 people * 2 days = 12 (man-days)
we can set up a ratio
\[ \frac{h}{4p}=\frac{H}{12} \]
and H= 3h/p

Answer 43

omg @saifoo.khan the day @karatechopper knows more than you has come :O

Answer 44

Lol @lgbasallote
Have you heard about this proved?
Every dog has his day.

Answer 45

i also heard that every dog has his bone

Answer 46

lol. I dont know about bone thing.

Answer 47

= 6 painters * 2 days * h house/ ( p painters * 4 days )
= 12 h/ 4p
= 3h/p

Answer 48

saif r u calling my a dog? im sorry i take human food not biscuits:P

Answer 49

@karatechopper , no sis. it's just a proverb meaning that everyone has his own day.
