Answer
22 times. (times given are approx) 1:05a 2:10a 3:15a 4:20a 
5:25a 6:30a 7:35a 8:40a 9:45a 10:50a 12:midnight etc. Both 
of the "eleven o'clock" overlaps never occur; they turn 
into the "midnight" and "noon" overlaps. The hour hand 
is "running away" from the minute hand.

Answer
The answer is twenty-three.

Most people quickly realize that the answer has to be 
twenty-four, give or take. The issue is nailing down 
that "give or take" part. Recognize, first of all, that 
there is nothing capricious about the overlaps. Both hands 
move at fixed speeds.

Therefore, the time interval between overlaps is a 
constant. This constant interval is a little more than an 
hour. At midnight, the hour and minute hands are exactly

superimposed. It takes an hour for the minute hand to make 
a complete circuit In that same time, the hour hand has 
moved 1/12 of a circuit to the numeral 1. It then takes 
another five minutes for the minute hand to catch up to 
where the hour hand was, in which time the hour hand has 
crept a bit farther.... Before getting sucked into a Zeno's 
Paradox, let's settle for the moment by saying that the 
interval is a little more than sixty-five minutes. We also 
know that the exact interval has to divide evenly into 
twenty-four hours, since the day ends as it started, with 
both hands up and overlapping. In fact, it has to divide 
evenly into twelve hours. The way the hands move in the 
P.M. is an exact replay of the way they move in the A.M. 

Focus on the twelve-hour period from midnight to noon. The 
hands cannot overlap twelve times in that period, for if 
they did, it would mean that the interval between overlaps 
was 12/12, or exactly one hour — and we know it's a bit 
more than sixty-five minutes. No, there must be eleven 
overlaps in a twelve-hour period. That means the interval 
between overlaps is 12/11 hour, which comes to 65.45 
minutes. This must be the precise interval that we balked 
at calculating a moment ago. Doubling eleven gives twenty-
two overlaps in a twenty four- hour period. Twenty-two is 
the answer — unless you want to split hairs. Should you 
count the overlap at the midnight that begins the day, and 
also at the midnight that ends the day, the answer is 
twenty-three.

Answer
It can be reduced to a fencepost problem... 

if you have two hands x (faster hand) and y (slower hand),
then the number of fenceposts is the number of circuits x
needs to make for y to make one complete circuit. The number
of overlaps of x and y is the number of spaces between the
fenceposts.

Question
Why is it that hot water in a hotel comes out instantly but 
at home it takes time?
Rank Answer Posted By  
 Question Submitted By :: Swapna
I also faced this Question!!   © ALL Interview .com
Answer
Simple. Hotel has customers and a customer will never wait 
for things. They have to be ready to him handy. Thats why 
they have a overhead tank with water heating 24*7. 

Where as in home its all our schedule and we can do the way 
what ever we like (:) you can't blame anybody)

Ofcourse these days getting 24*7 hot water is a quite 
common in home's too..

Ram
 
 
Answer
In home systems, the water sits a while stagnant in the
pipes until you open the valve to let some out.  It takes a
bit of time for the hottest water to reach the open valve. 
Many commercial buildings have a recirculating hot water
system in which a small pump circulates the water from the
hot water tank, out through the system and returns it to the
tank.  City water pressure still forces it out the tap when
you open the valve, but since the water is never stagnant,
it never cools off in the pipes, and so it is always hot
when you open the tap.

Question
Why are beer cans tapered at the top and bottom?
Rank Answer Posted By  
 Question Submitted By :: Swapna
I also faced this Question!!   © ALL Interview .com
Answer
The metal on the lid of the can is significantly thicker 
than the metal on the sides. This means that a great deal 
of raw materials can be saved by decreasing the diameter of 
the lid, without significantly decreasing the structural 
integrity or capacity of the can. This results in savings 
of about 15% versus a non-tapered can.

Question
Two MIT math graduates bump into each other at Fairway on 
the upper west side. They hadn't seen each other in over 20 
years. 
The first grad says to the second: "how have you been?"
Second: "Great! I got married and I have three daughters 
now"
First: "Really? how old are they?"
Second: "Well, the product of their ages is 72, and the sum 
of their ages is the same as the number on that building 
over there.."
First: "Right, ok.. oh wait.. hmmmm.., I still don't know"
second: "Oh sorry, the oldest one just started to play the 
piano"
First: "Wonderful! my oldest is the same age!"
Problem: How old are the daughters?

I also faced this Question!!   © ALL Interview .com
Answer
The Second grad specifies that -  "Great! I got married and 
I have three daughters NOW" 

This means that the third daughter was recently born and 
hence she will be less than a year - which we consider as 1.

So that leaves us with the two daughters whose ages 
multiply to 72.

The factors of 72 are : 72&1, 36&2, 24&3, 18&4, 12&6, 8&9 

Now if the MIT Grads left school around their twenties, it 
means they are in their forties now. Which means that even 
if they got married as soon as they graduated and had a 
child, there would be a twenty yrs difference between the 
father and the dughter. Hence &2&1, 36&2 are omitted.
Leaving us with  18&4, 12&6, 8&9.

Now they say the right age to start piano lessons is 12 so 
that leaves us with 12&6. Hence the daughters are ages 12, 
6 &1.

Answer
We know the guy trying to work out the ages can see the
number. We therefore know that *he* knows exactly what
number it is. We don't know what the number is, but that
doesn't matter. The important information revealed here is
that the guy knows what the number is.

Why is that important information? Well, we know that even
though he knows this number, that's insufficient information
for him to work out the ages.

So what information do we have at this stage? We know the
product of the ages is 72. And we know that even if you know
the sum of the ages as well as the product, that's not
enough to work out the individual ages.

I believe these are all the possible ages that give a
product of 72 where the numbers are all under 20, and I've
shown the sum of the ages next to them:

1, 8, 9   : 18
1, 6, 12  : 19
1, 4, 18  : 23
8, 3, 3   : 14
12, 2, 3  : 17
18, 2, 2  : 22
3, 4, 6   : 13
2, 4, 9   : 15
2, 6, 6   : 14

We can actually eliminate most of these now. They can't be
1, 8, and 9, because those add up to 18, and, significantly,
that's the *only* combination that adds up to 18. Remember
the guy knows the sum total (even if we don't). If it had
been 18, he'd have worked out from that information alone
that the ages were 1, 8, and 9.

You can eliminate all the combinations with a unique sum. If
those had been the ages, the guy would not have needed that
last clue.

In fact there are only two possible outcomes: 2, 6, and 6,
or 8, 3, and 3. Of all the sets of 3 numbers less than 20
that have a product of 72, these are the only ones with a
non-unique sum.

now since in the combination of 6,6,2 the "oldest" daughter
could not be as we have 2 daughters of equal age the answer
must be 8,3,3.

Answer
It's actually pretty simple...

The guy does not know the answer, if he knows only the sum &
product. he does know the answer if he knows the sum &
product & that the largest number is unique.

Therefore, there must be only one combination where the
largest number is unique, and one or more combinations where
the largest number is not unique. In other words, x^2 + y =
72, where x > y.

There is only one set of numbers that works: {6,6,2}.
Therefore, they are talking about Building 14.

So you need x+y+z=14, and x*y*z=2*2*2*3*3

We've made the leap of logic and it is just math from here.
