Anoop managed to draw 7 circles of equal radii with their centres on the diagonal of a square such that the two extreme circles touch two sides of the square and each middle circle touches two circles on either side. Find the ratio of the radius of the circles to the side of the square.

a. (2+ 7√2):1

b. 1:(2+ 6√2)

c. 1:(4+ 7√3)

d. 1:(2+ 7√2)

a. (2+ 7√2):1

b. 1:(2+ 6√2)

c. 1:(4+ 7√3)

d. 1:(2+ 7√2)

last 2 circles will have radius perpendicular to sides..so dist. b/w diagonal & centre will be sqrt(2)r .....

now remaining dist. is r , 5 circles will b 10r and last circle will b sqrt(2)r + r.

total= 10r + 2*(sqrt(2)r+r) = sqrt(2) side

so ratio of r:s = 1/2+6sqrt(2)

now remaining dist. is r , 5 circles will b 10r and last circle will b sqrt(2)r + r.

total= 10r + 2*(sqrt(2)r+r) = sqrt(2) side

so ratio of r:s = 1/2+6sqrt(2)

"Then travels for 1 hour and sees the same 2 digits in reverse order."

10x + y + 1s = 10y + x

10x - x + s = 10y - y

9x + s = 9y

1 hours later he sees that the milestone has the same 2 digits with a 0 between them."

10y + x + s = 100x + y

10y - y + s = 100x - x

9y + s = 99x

Rearrange the above two equations for elimination

9x - 9y + s = 0

-99x+9y + s = 0

----------------adding eliminates y

-90x + 2s = 0

2s = 90x

s = 45x

x has to equal 1, then s = 45 mph (If x=2 and s=90 mph, when added to

a two digit milestone, could not be at another two digit milestone.)

Find y

9x + s = 9y

9(1) + 45 = 9y

9 + 45 = 9y

simplify divide by 9

1 + 5 = y

y = 6

Speed is 45 mph

Ans:.25

Here the data about the distance is of no use.

For radius of 1 m if dart is inside the circle of 1/2 m radius the dart is closer to center than periphery

so area of 1/2 m circle is pie/4

area of board is pie

So probability = 0.25

Ans:.25

Here the data about the distance is of no use.

For radius of 1 m if dart is inside the circle of 1/2 m radius the dart is closer to center than periphery

so area of 1/2 m circle is pie/4

area of board is pie

So probability = 0.25

means

1 programmer take 12 minutes to write 1line

72 programmer take 12 minutes to write 72line in total

72 programmer take 72 minutes to write 432(72*6)line in total

because the time increased into 6 factor(72/6)

On planet zorba, a solar blast has melted the ice caps on its equator. 8 years after the ice melts, tiny plantoids called echina start growing on the rocks. echina grows in the form of a circle and the relationship between the diameter of this circle and the age of echina is given by the formula

d = 4 * v (t – 8 ) for t = 8

where d represents the diameter in mm and t the number of years since the solar blast.

Jagan recorded the radius of some echina at a particular spot as 8mm. How many years back did the solar blast occur?

a]24

b]12

c]8

d]16

ANS::

d= 4 * v (t – 8 )

in this equation v represents an square root.

d = 4 * sqrt(t-8)

d = 16 as r= 8 given

thus 16 = 4 * sqrt(t-8)

4 = sqrt (t-8)

t-8 = 16

QUESTION NO::33

A hunter leaves his cabin early in the morning and walks one mile due south. Here he sees a bear and starts chasing it for one mile due east before he is able to shoot the bear. After shooting the bear, he drags it one mile due north back to his cabin where he started that morning. What color is the bear?

a]Brown

b]Black

c]Grey

d]White

Ans::

From North Pole, there are an infinite number of points about 1 mile away , where you can walk 1 mile south, walk one mile east (all the way around the earth back to the same spot), and then back north again,

This is only possible if the cabin of man is at North Pole.

He can walk one mile due south, then one mile due east and finally one mile due north where he finds his cabin again. This means that his cabin can only be at the north pole, and for that reason the bear will be white.

Alice and Bob play the following coins-on-a-stack game. 20 coins are stacked one above the other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is to bring the gold coin to the top by repeatedly moving the topmost coin to another position in the stack.

Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (0 = i = 20). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2-move. If the gold coin happens to be on top when it's a player's turn then the player wins the game. Initially, the gold coinis the third coin from the top. Then

a) In order to win, Alice's first move should be a 1-move.

b) In order to win, Alice's first move should be a 0-move.

c) In order to win, Alice's first move can be a 0-move or a 1-move.

d) Alice has no winning strategy.

ANSwer OF 55::

since it is dark....

take worst case

satisfy largest number first.....

since she wants it in pair

32 red

24 yellow

1+1 yellow+blue

2 blue

=60

or

as lights off

first we remove 32 red

then 24 yellow

then 1 yellow 1 blue

and then 2 blue

thus we get pair for all colors

so total = 60

since it is dark....

Ramu & Sangeeta went for biological analysis to a island which is 34km from their place. They travelled in a boat which went at a speed of 2m/s. when they are in half a distance in the boat sangeeta note there are 7 leg & 8 leg octopuses under the water. Ramu counted the total number of legs of octopuses and got 54. Sangeetha instantly said I know how many 7 leged octopuses are there under the water. They both reached the island after 20 min they left . How many seven leged octopuses does sangeetha calculate?

ans-5000

cubes required-

5x6x7=210

210=.03x

x=7000

if cuboid is hollow then cubes required

3x4x5=60

60=.03x

x=2000

so ans=7000-2000=5000
