Three friends went to buy 3 toys of 20 rupees each. Since they bought 3 pieces, the shopkeeper decided to give a discount of 5 rupees. He sent back 5/- through his servant to be given to the 3 friends. For easy division among the frends, the servant secretely put 2 rupees in his pocket and gave 1 rupee each to 3 of them as the discount. Thus, a toy for each of them cost 20-1 = 19. Total cost for 3 toys comes: 19 x 3 = 57. The servant has 2 rupees in his pocket. 57 + 2 = 59. But they had spent 60/- (20 x 3) for the 3 toys in the beginning, but here the calculation comes only to 59/- (i.e. 19x3= 57 + 2(servant's pocket). Where is the 1 rupee gone ???

Right, so maybe posting a question on smashing gorillas was a little insensitive in the OTHER PETS category. Sorry.

Okay, same concept, hypothetical beings. A particle accelerator is reconfigured to send two smurfs barreling toward each other at extremely high speeds, perhaps approaching light speed, to see what sounds they make upon collision.

Note that smurfs are not, technically, alive and are actually a byproduct of alchemy, so most conventions of humane treatment don't apply.

if a bowling ball weighing 16 pounds traveling at 23 MPH and hits bowling pins weighing 3.5 pounds (only one pin was hit) what is the unit of force upon impact. if i could get the formula to figure the problem, that would be a great plus! i dont think this matters, but the lane is 60 feet long and 5 feet wide. the speed does not change from start to finish.

My club has 5 cultural groups- Literary, Dramatic, Musical, Dancing and Painting groups. The literary group meets every other day, the dramatic group meets every third day, the musical- every fourth day, the dancing- every fifth day and the painting- every sixth day. The 5 groups met, for the first time on the New Years' Day of 1975 and starting from that day they met regularly according to schedule.
Now, can you tell how many times did all the 5 meet on one and the same day in the first quarter? Ofcourse, the New Year's Day is excluded.
One more question- were there any days when none of the groups met in the first quarter, and if so, how man were there?
