We can consider a saucer as a circle of Radius R.
Draw a circle and 6 circles can be drawn on its circumference touching each other. If you join centers of the circles a hexagon will be created having edge of length 2R. Similarly another 12 circles can be drawn on the circumference of these six circles. A hexagon can be made by joining centers of these 12 circles having edge length = 3R.
So, concentric hexagons can be created having an A.P. of circles: 1, 6, 12,18, 24, 30, 36, 42. We need to stop here because the if we join any two opposite vertices of the largest hexagon, there will be 15 circles in line.
If there are even no. of circles per side of the outer most hexagon, an outsider can be placed centrally. and 2 more can be placed on circumference of this one. Like this, 3 outsiders can be there.
So in total, 1+6+12+18+24+30+36+42+ (3*6) = 187 saucers.

None!!
Here t denotes time in minutes.
X denotes path not visited by any bus yet.
b1,b3,b5……..denotes the buses which start from left side of the road
while b2,b4,b6……denotes the buses which start right side of the road!!!
(number)…..denotes how many buses they meet on the way…….when t=0; b1(0)———X———-X———-X———b2(0)
when t=10; b3(0)———b1(0)———-X———-b2(0)———b4(0)
when t=20; b5(0)———b3(0)———-b1(1)b2(1)———-b4(0)———b6(0)
when t=30; b7(0)———b5(1)b2(2)———-b3(1)b4(1)———-b1(2)b6(1)———b8(0)
when t=40; ……………………………………..every bus will meet at least one bus during its path from one end to another.

12/12/2013
The papers can be identified by the date written by them because the British and Americans write the date of the day in the different way so these papers can be segregated easily.
explanation :
the Americans write the date of the day and month and years as : month/day/year
the British write the day and month and year as :day/month/years
But their dates were same? How? Because the date was actually 12/12/2013 and for this the month and the day number were equal!! So the papers couldn’t be separated!!

He starts at the south pole and travels north 100 meters.
Now is 100 meters from the South Pole. He then travels (still at 100 meters north of the South Pole) 100 meters to the West.
Since he is still 100 meters north of the South Pole, when he goes 100 meters south,
he ends up back where he started.
With only three perpendicular movement u can reach back to your cabin if and only
if your cabin have been situated on the pole!!
So he sees a penguin!!!- 4330 views
