  • 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...

    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=204.83-13.88

    x=190.95 m/sec which is the speed of second train

    the next puzzle is posted below.

    ANYONE GIVING RIGHT ANSWER in 24 hours WILL BE MERKED AS "ANSWER"

     

    question:

    If the operation,^ is defined by the equation x ^ y = 2x + y,what is the value of a in 2 ^ a = a ^ 3

    Saturday, March 24, 2007 9:06 AM
  • 2^a = a^3
    2*2 + a = 2*a + 3
    4 + a = 2a + 3
    4-3 = 2a - a
    a = 1

    ans a = 1

    QUESTION FOR ALL MEMBERS OF FORUM Q:12

    Ans is 3...
    out of 15, 3 hv studied nothing.. so 12 hv studied something...
    now a total person with both latin & greek are 15,
    ie 3 extra... this 3 hv studied both
    so 3(both) + 4(latin) + 5(greek) + 3 (nothing) = 15 (total)...

  • the answer provided by varun_modi for puzzle 13  is correct

    next question:

        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...

    Sunday, March 25, 2007 6:38 AM
  • 1st number = 0
    2nd            = 0 + 1 = 1
    3rd             = 1 + 4 = 5
    4th              = 5 + 8 = 13

    6th            =  25 + 16 = 41
    7th            =  41 + 20 = 61

    ans :-  61
    Sunday, 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...

  • ANSWER TO PUZZLE 16

    sorry varun your answer is wrong
    here's the answer:

    i am solving this question statement-by statement:

    according to given conditions

    peter=paul+ 1                                     .....eqn 1

    pat=pam+1                                         .....eqn 2
     
    peter+paul=10+(pat+pam)               .....eqn 3

    peter+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 +peter-1=35

    peter=18 ANS

    -> 16*6  +  3
    -> 96 + 3
    -> 99

    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?

  • using any mathematical operator and only four 4's can u get the output as "625"

    "eg" 4 + 4 - 4 - 4 then output is 0 

    Tuesday, March 20, 2007 2:31 PM
  • ans :- (4+4/4)^4

    = (4+1)^4

    =(5)^4

    =625

  • 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=204.83-13.88

    x=190.95 m/sec which is the speed of second train

    the next puzzle is posted below.

    Ans is 3...
    out of 15, 3 hv studied nothing.. so 12 hv studied something...
    now a total person with both latin & greek are 15,
    ie 3 extra... this 3 hv studied both
    so 3(both) + 4(latin) + 5(greek) + 3 (nothing) = 15 (total)...

    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..

  • ANSWER TO PUZZLE 16

    sorry varun your answer is wrong
    here's the answer:

    i am solving this question statement-by statement:

    according to given conditions

    peter=paul+ 1                                     .....eqn 1

    pat=pam+1                                         .....eqn 2
     
    peter+paul=10+(pat+pam)               .....eqn 3

    peter+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 +peter-1=35

    peter=18 ANS

    Answer to your question is

    (16 * 12 / 2)  + 3 = 99

    -> 16*6  +  3
    -> 96 + 3
    -> 99

    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

     

      =>113.04 units     
    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.....

  • @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)
    =3.14

  • 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%
