Puzzle: Year on October 2, 2001, the date in MMDDYYYY format was a palindrome (same forwards as backwards).10/02/2001
When was the last date that this occurred on before year 2001?

(Hint: it was not happened in 1900 because for that day of the month would be 91 which is impossible)

Solution: We know the year has to be less than 2001 since we already have the palindrome for 10/02.

It can't be any year in 1900 because that would result in a day of 91. same for 1800 down to 1400. it could be a year in 1300 because that would be the 31st day. so whats the latest year in 1300 that would make a month?

At first we thought it would be 1321, since that would give us the 12th month, but we have to remember that we want the maximum year in the 1300 century with a valid month, which would actually be 1390, since 09/31 is a valid date.
but of course, and of course, there are not 31 days in september, only 30.

so we have to go back to august 08 which means the correct date would be 08/31/1380.

Puzzle: What is the angle between the minute hand and the hour hand at 3:15 on an analog clock?
---------------------------------------------------------------------------------------------

Solution: 12 hours on the clock make 360 deg.
so 1 hour is 30 deg.
The hour hand will be directly on the 3 when the minute hand is at 12 (3:00).
After 15 minutes or 1/4 of an hour, the hour hand
will be 1/4 * 30 deg = 7.5 deg.
away from the minute hand

Four friends need to cross a bridge to get back to their home at night. Unfortunately, they only have one flashlight. The bridge is too dangerous to cross without a flashlight, and it’s only strong enough to support two people at any given time.

Each of the them walks at a different speed.
One can cross the bridge in 1 minute,
another in 2 minutes,
the third in 5 minutes,
and the fourth one takes 10 minutes to cross.
How much minimum time they will take to cross the bridge?

Solution:

According to your question let A,B,C,D be the four friend who take 1,2,5,10 minutes to cross the bridge.

NOW
----------

1) A and B go together to other end of bridge with flash light( time take = 2 minutes)
2) B remains there and A returns to the start point with flash light( Time taken = 1 minute)
3) C and D go together to other end of bridge with flash light( time taken = 10 minutes)
4) B returns to the start point with flash light(time taken=2 minutes)
5) Both A and B go to other end of bridge with flash light( time taken=2 minutes)
Total time taken = 2+1+10+2+2=17 minutes.

1. A c-pole of 200ft is 250ft from the d-pole which is 150ft high..Two pigeons are sitting at the top of each poles(one in one pole)Both pigeon fly towards a grain which is present between the 2 polesat the same speed.what is the distance between the c-pole and the grain?

Answer: pole c is 200 ft.
pole d is 150 ft.
Dist b/w these poles is 250 ft.
Assume grain is place at dist x from pole c.
so that now the dist b/w c and d is x + (250-x)
now since the speed of the bird is same and they both reach at same time. The Dist travelled by them will be same. i.e., the hypotenues will be same.
So 200^2 + x^2 = 150^2 + (250-x)^2
solving this x = 90 ft.
Hence Dist b/w c-pole and grain is 90 ft.

2. A man had covered 2/3 of distance by cycling and remaining covered on feet. For this he took twice the time to the cycling. Find how much speed is greater for cycling than on feet?

Answer: Suppose distance is d,
cycling speed is v and foot speed is u
then 2*(2/3d)/v=(1/3d)/u => v=4u
So 4 times greater

1. 40 cows graze a pasture in 40 days,30 cows graze the same pasture in 60 days.how many days does 20 cows take to graze it.

Ans: 120 days.
Let 'x' be the amount of grazed by a cow per day,
Let 'y' be the growth rate of grass per day,
Let 'z' be the amount of grass present initially,
So, 40 cows can graze (40*x) amount of grass per day and (40*x*40) amount of grass for 40 days.
For 40 days, the growth of grass is (40*y)
So, (40*x*40) = (z + 40*y)
For 30 cows it takes 60 days, so,
(30*x*60) = (z + 60*y)
so, 1600x - 40y - z = 0 ----- 1
1800x - 60y - z = 0 ----- 2
Subtracting we get, 10x = y , Sub. 10x=y in 1 or 2, we get z = 120y or z = 1200x
For, 20 cows,
20*x*N = z + N*y
Sub, 10x=y and (z=120y or 1200x), we get N = 120
Therefore, for 20 cows it takes 120 days to graze.

2. A person from washington came to india.One evening at 6.00 p m he started walking at the speed of 40 km/hr andclimbed the slope at speed of 30 km/hr.From there he walked back to the source at the same speed at 9.00 p m.what is the distance he covered in one way.

Answer: 105 km
read the question carefully...
he starts his return journey at 9:00pm..so one way journey time is 3hrs
So the eqn becomes
avg spd =35kmph
(x+y)/35=3
x+y=35*3 =105

1. what is the 5 digit number which has only 2 prime numbers in it and satisfies the followingcondition.
a. 3rd digit is the largest
b. 2nd digit is the smallest
c. 1st digit is one less than the 3rd digit and greater than theaddition of 4th and 5th digit.
d. 5th digit is between the 1st and 2nd digit and half of the 4th digit.
1 is not considered as the prime number

Solution:
2nd digit is the smallestso it must be 1.
3rd digit is the largestso it can be 9 and
the first digit is 8.
1st digit is greater than theaddition of 4th and 5th digit.
so it can be 1,2;2,1;3,4;4,3;2,3;3,2;2,4;4,2
but 5th digit is between the 1st and 2nd digit and
half of the 4th digit
so it can be 4 and 2 and so we should have 1 more prime no.
so the third digit cannot be 9 it should be 8 and the first digit is 7.
so the number is 71842.

2. (Most Difficult one)
What is the value of X,Y and Z?
X X X X
Y Y Y Y
Z Z Z Z
-----------
Y X X X Z
-------------

Solution: Well, to get X+Y+Z = Z, we should have X and Y as O which is not possible, So if we take X and Y such that X + Y = 10, we can get X + Y + Z = Z, carry 1.

At the next stage, we should get (carry)1+X+Y+Z = X, so we have to choose Y and Z such that Y + Z = 9. So, 1+X+Y+Z = X, carry 1.

At the next stage also, 1+X+Y+Z = X, carry 1.
At the final stage we have to get, 1+X+Y+Z = YX. Since, 1+X+Y+Z gives the value X and carry 1 we get the value fo Y as 1.

1. A father is talking with his son about his fat's age. He said that "My father was 8 yr at the X power 2 year. ". "Dont confuse boy , it was 20 th century". What is the yr boy's GF born.

Solution: Granpa was borned in 20 th century i.e 1900-2000 When he was 8 Yrs old then the year was square of a number X. Since only the square of number 44 is the number that defines the year in between 1900 and 2000 and its 1936. Since the granpa of boy was 8 yrs old so the original year of birth will be 1928.

2. There r some groups and lodges. And there have given some conditions. Depending onthis we have to find how many lodges and how many men in each group.

3. In a county , the basketball tournament was succeeded by Doubly eliminating process. If one team loses two matches , it will be disqualified] so if there are 51 teams then what will be the max no of matches.

Solution :
It is n + (n-1) , in this case n is 51. Here is the explanation: say it is like a playoff tournament (each team is allowed to enter next round if it wins) then between 2 teams to decide a winner we play 1 game, if there are 3 teams we need to play 2 games, if it is 4 teams then 3 games and so on...
but since here it is two losses that disqualifies a team, and we are considering the maximum possible (worst case scenario) , if there are 2 teams and each team wins 1 game, then the third game is the decider, similarly if there are 3 teams, allow each team to play with all the other teams once first (3 games, which means 3 wins and 3 loses) lets assume each team 1 game and lost 1 (this results in the worst case scenario again) and during the second iteration, two games are enough ( 2 wins, 2 loses) and we have a winner here ....
hence the final answer is n + (n-1)
