Hi friends,
Hi friends,
Hope u had nice time with C teasers. (Whether it teased u or u
teased it, God only knows!!). This session contains some general
handwork puzzles & simple mathematical questions. Get, Set and
Go!!!
1. Here is a figure of 9 dots.Join them using only 4 straight
lines
without removing your pencil.

2. The first 13 letters have been classified on some criteria
here.
The puzzle is to classify the remaining 13 in the same 4
categories.
1. A M
2. B C D E K
3. F G J L
4. H I
3.Here is a mathematical one
6,20,36,48,50,?,0
4. The master ordered his gardener to plant 25 seeds in 12
straight
lines in such a way that each line will have 5 seeds.The
poor
gardener was confused and sat down bewildered.Can you help
him?
5. A famous scientist had been experimenting to find out a
liquid
which would dissolve everything.One day jumped in joy as
he found the formula of the liquid.He immediately went to
register
his formula but had never thought of a complex problem which
mocked
his entire effort.Can you guess what the problem was?
6. Can you weigh 27 balls in 3 chances to find out the odd
ball(lighter or heavier) ?
7. SHEPHERD'S PUZZLE
On a certain pasture,the grass grows at an even rate. It is
known that 40 cows can graze on it for 40 days before the
grass
is exhausted,but 30 cows can graze there as long as 60 days.
Now tell me , how many days would the pasture last if
20 cows were to graze it?
8. AROUND THE WORLD
A rope-winder, who, in school, had learnt that the earth is
round, worked all his life to make a rope long enough to go
around the globe.
When he finally laid it along the Equator and pulled the
ends tight, he realized that it was a yard too long. He
however,
joined the two ends together considering that one yard
amongst
millions would be insignificant.
Assuming that the rope was stiff enough to maintain a
uniform distance from the surface all round the equator, how
far
would it stay from the earth.
9. What comes next and why?
0,60,90,108,120,?
10. 1,2,6,10,0,4,5,9,?

lines need not end at the points specified, isn't it?
2. Here you need to analyze the alphabets geometrically.
1. symmetry about a vertical axis
T U V W Y
i.e.,
if you divide the letter into two parts in the
vertical direction the two halves will be similar.
2. symmetry about a horizontal axis
---------
3. absence of symmetry about any axis
N P Q R S Z
4. symmetry about both axes
O X
3. 36 (6^2 * 1 or (x[n-1]+x[n+1])/2-1+(n-1)*3

Ten lines (parallel to the sides) and two diagonals.
5.Even if he were to be given the patent to market the
liquid,
in which container would he be able to store(pack) the
liquid?
(Remember, it dissolves EVERYTHING).
7. 120 days. Forming three equations with three unknowns,
the
variables being
1. Initial height of grass
2. Height of growth/day
3. Amount grazed/cow/day
Solving
I + 40 H = 40*40 A
I + 60 H = 60*30 A
I + D H = D *20 A
8.In yards,
(2nR + 1) = 2nX
Hence
X = R + 1/2n
Therefore the distance above the earth is
(1/2n)*3*30 cms
= 14.3181818182 cms
9. 128.5714
They are the angles enclosed between any two consecutive
sides of plane figures having 2,3,4,5,6,7 sides.
10. 3,7,8
The first 4 numbers are THREE lettered words in the
numerical order. The next 4 are FOUR lettered in similar
order.
Hence the next numbers should be FIVE lettered in order.

Next session will be "Technical" !! Beware and Watch out for it
!!
Until then,
