dear "jkj_charles" friend dont mind, i am not commenting you but one thing i see in puzzle is that rather 4 should have come before 5 (though they have same letters in common but) the value of 4 is numerically smaller than 5 an series should go in some particular order else it is unstructured.Friday, March 16, 2007 4:49 AM

dear jkj its not 6 cigars, let someone else post the correct answer else i will post the correct one tommorrow.Sunday, March 18, 2007 2:56 PM

dear u have a good sense of humour but the answer is not correct let me tell u that by ciggrete butts we mean to say (unused part of ciggrete) specially left after smoking, u may rejoin these parts to make a new cigrette.Sunday, March 18, 2007 5:51 PM

Ahhh i didnt knew that.. in that case the answer is 7, because for the 1st one u use 6, now left with 30... now after smoking every cigrette you get one more butt so from now on you need only 5 butts more.. ie 30/5 = 6....
so in total you can have 7 cigrette... i think this is the answer...
you can expect more quiz over here from my side ;) just waiting for your answer than ill start...

the trains puzle below this post
Friday, March 23, 2007 8:45 AM 
QUESTION FOR ALL
A train has lenght of 108m, it is travelling at a
speed of 50km/hr. a second train with length of 1121m,
opposite direction to first train, passes the first
train in 6 seconds. What is the speed of the second
train?Friday, March 23, 2007 8:59 AM 
ANSWER TO PUZZLE 11
as no one could do the above problem i am posting solution for this:
with the concept of relative velocity
relative distance of two trains=108+1121
total time taken to cross the distance by the trains is : 6sec
let the speed of second train is x m/sec
speed of first train = 50 kmph i.e. 50*5/18 mtr/sec=13.88 m/sec
so the total speed of trains as they r traveeling oppsosite to each other(relative velocity)=13.88+x m/sec
so speed =distance/time
13.88+x=(1229/6)
13.88+x=204.83
x=204.8313.88
x=190.95 m/sec which is the speed of second train

A monkey starts climbing up a tree 20ft. tall. Each hour, it hops 3ft. and slips back 2ft. How much time would it take the monkey to reach the top?
Saturday, March 24, 2007 4:32 PM 
The ans is 18 hrs...
the monkey covers an average of 1 ft every hr.. at end of 17th hr, it will cover 17 ft.. now when he jumps he reaches to 20th feet in next hr ans so don need to slip back..
Thus the ans comes out to be 18 hrs...Saturday, March 24, 2007 5:50 PM

let the daughter rec x, so a total of 4x
son rec twice of a daughter ie 2x so total 10x
mother rec 3 times of son ie 6x

total = 20x = 10,000,000

PUZZLE:14
A monkey starts climbing up a tree 20ft. tall. Each hour, it hops 3ft. and slips back 2ft. How much time would it take the monkey to reach the top?
Saturday, March 24, 2007 4:32 PM 
The ans is 18 hrs...
the monkey covers an average of 1 ft every hr.. at end of 17th hr, it will cover 17 ft.. now when he jumps he reaches to 20th feet in next hr ans so don need to slip back..
Thus the ans comes out to be 18 hrs...Saturday, March 24, 2007 5:50 PM

PUZZLE 15
complete the series
0, 1, 5, 13, 25, 41, ??????
Sunday, March 25, 2007 6:38 AM 
1st number = 0
2nd = 0 + 1 = 1
3rd = 1 + 4 = 5
4th = 5 + 8 = 13
5th = 13 + 12 = 25
6th = 25 + 16 = 41
7th = 41 + 20 = 61
ans : 61Sunday, March 25, 2007 11:09 AM 
The series is : 0,1,5,13,25,41,61.....
The logic is, the series starts with 0 then 1 is added to it...then 4 ...then 8...then 12...likewise multiples of 4 r added to the previous number...Sunday, March 25, 2007 11:20 AM 
PUZZLE 16
Peter picked one pepper more than Paul. Pat picked one pepper more than Pam. Peter and Paul picked 10 more peppers than Pat and Pam. Peter, Paul, Pat and Pam picked 60 peppers. How many peppers did Peter pick?
Sunday, March 25, 2007 7:47 PM 
peter & paul = 35
Pat & pam = 25

Total = 60
peter = 18
paul = 17

total = 35
pat = 13
pam = 12

Total= 25
Thus you have the ans above..............Monday, March 26, 2007 4:02 AM 
ANSWER TO PUZZLE 16
sorry varun your answer is wrong
here's the answer:i am solving this question statementby statement:
according to given conditions
peter=paul+ 1 .....eqn 1
pat=pam+1 .....eqn 2
peter+paul=10+(pat+pam) .....eqn 3peter+paul+pat+pam=60
=>peter+ paul = 60(pat+pam) .....eqn 4
by equation 3 and equation 4
peter+paul = 10 + 60 (peter + paul)
peter +paul =35 .....eqn 5
by equation 5 and euation 1
peter +peter1=35
peter=18 ANS

Kanav if you just check it out.. i have given the same answer.. my method of calculating is different but the ans is same and right one, satisfying all the conditions you gave...Monday, March 26, 2007 6:40 PM

let the daughter rec x, so a total of 4x
son rec twice of a daughter ie 2x so total 10x
mother rec 3 times of son ie 6x

total = 20x = 10,000,000
x = 500,000
widow = 6x = 3,000,000

What number should come next in this series
479126 62974 4796 697 ?( i personally feel that this series is quite hard to digest,so i give a hint
there is reversal of numbers and one more thing is done(which u have 2 find), and finally the last number is to be found by you ppl.)
Tuesday, March 27, 2007 5:22 PM 
JUST REVERSE THE NUMBERS AND ELIMINATE THE SMALLEST DIGIT FROM THE NUMBER:
HENCE THE ANSWER IS: 79

PUZZLE :18
Replace the asterisks by the correct mathematical signs to make the expression equal to 99.
16 * 12 * 2 * 3 = 99Sunday, April 15, 2007 7:22 PM 
Hey Kanav nice to see you back in action.. where have you been...
Answer to your question is
(16 * 12 / 2) + 3 = 99
> 16*6 + 3
> 96 + 3
> 99Sunday, April 15, 2007 8:18 PM 
a answer by varun is correct , the next question is:
QUESTION 19
Nine equal circles are enclosed in a square whose area is 36sq units. Find the area of each circle
Monday, April 16, 2007 8:43 AM 
6 units per side of square
2 units per circle diameter
A=pi r squared, right?
So Area = Pi x 1
So area of each circle is Pi sq units...right?
Monday, April 16, 2007 10:24 AM 
hii..
the radius of each circle is 6 units..
therfore, area of each circle=pi *r*r
=>pi*6*6
Monday, April 16, 2007 12:41 PM 
Hiren's answer is right....
i don know how to draw it here or else i would have drawn it.. but just imagine it for the time being...
9 Circles are to be fitted in a box... so there will be 3 rows with 3 circles on each row.. It will be like a 3x3 matrix... So now we can see that the circles are touching with each other and you can draw a straight line from one side of the square to the other side and all the diametres will fall on them...
as square is of 6 units per side,
so we can say that 2 unit diameter.. 1 unit radius.. thus we have the radius as
pi x r quared = pi = 22/7
........................................................
Now kanav you missed out something in the quesion.. that the circles should not be overlapping others and that the circles are of maximum size possible.. hence theie can be many answers to this question like even .5 units radius cirlces.....Monday, April 16, 2007 4:02 PM 
@varun .... if my answer is right, mark it as answer... if u don't mind...

I m not running this thread bro.. Kanav is running it and don't worry, he will mark it as answer.. he is regular at doing itMonday, April 16, 2007 6:08 PM 
@varun, dear most of the times the things r to be taken as obvious you can only complain if there is twist in the reply which i give, for example Hiren and akash thought the most obvious thing which even i thought when i saw the question, but still thanks for the suggestion
dont look at the smiley seriously, just having fun.
@Hiren,your answer is correct but the explanation is given below:
ANSwer:
if there was only one circle in one square then side
of the square is equal to diameter of the circle.
NOW about the answer for the question:
9 Circles are to be fitted in a square
so there will be 3 rows with 3 circles.
now using the above fact imagine a square around each circle
hence there are 9 squares in a bis square
so
9*a*a=36
a*a=4
a=2
i.e the side of the square is 2 units this is equal to
diameter of the circle
hence the area is
pi*r*r
=3.14*(2/2)*(2/2)
=3.14Monday, April 16, 2007 7:21 PM 
QUESTION:20
Daal is now being sold at Rs. 20 a kg.
During last month its rate was Rs. 16 per kg.
By how much percent should a family
reduce its consumption so as to keep the expenditure fixed?Monday, April 16, 2007 7:27 PM 
ANSWER: 25%
because the rate of Dal has been increased by 25%..
Tuesday, April 17, 2007 2:57 AM 
20%
lets say i was consuming 10 KG @ 16 rs = 160 Rs Total Exp.
Now @ 20 Rs, my consumption will be only 80 Kg at same Exp.
so from 100 KG i reduced to 80 Kg, thus reducing my condumption by 20%Tuesday, April 17, 2007 3:10 AM 
obviously 20 %
because
(100 * 16) / 20 = 80
100  80= 20%
