Maths, logic, trivia, puns, general silliness - an assortment of stuff too disparate to go under any other title. In other words, same old rubbish. -1. A rebus: 012356789DRACULA -2. Give me a word that will fit in with the following group and explain why: settee, raccoon, embarrass -3. Two travellers spend from 3 o'clock till 9 o'clock in walking along a level road, up a hill, turning round and then following their tracks back home again. Their pace on the level is 4 mph, uphill 3 mph, and downhill 6 mph. Find the distance walked; also find (within half an hour) the time taken to reach the top of the hill. -4. Which of the following 5 sentences are true? a) It is not the case that 2 consecutive sentences are both false. b) There are fewer false than true sentences. c) It is not the case that 3 consecutive sentences are all false. d) It is not the case that 2 consecutive sentences are both true. e) There are exactly 3 false sentences. -5. I am using a number of 3-ft diameter rollers tp move a long heavy slab. Approximately how far will the slab move for each revolution of the rollers? -6. (A tricky one I think) You've got 6 marbles. 2 red ones, 2 blue ones and 2 yellow ones. Of each colour pair one marble is slightly heavier than the other but you can't tell them apart without weighing. All 3 light marbles all weigh the same, and all 3 heavy marbles weigh the same. Two marbles always weigh more than one marble. Now, weighing twice with a set of balance scales, can you separate the lighter marbles from the heavier ones? -7. Whilst you are in the theatre, there is announcement that "Mr Sands is in the foyer". What might be your reaction and why? -8. The first scientists to study fog were ---------.

3. Two travellers spend from 3 o'clock till 9 o'clock in walking along a level road, up a hill, turning round and then following their tracks back home again. Their pace on the level is 4 mph, uphill 3 mph, and downhill 6 mph. Find the distance walked; also find (within half an hour) the time taken to reach the top of the hill.
Same distance walked at 6mph and 3mph: @6mph.......(K hours)@3mph.......(2K hours) Total above distance = 6K + 3(2K) = 12K Average speed distance / time = 12K / 3K = 4 (not 4.5!)
So the 6 hours were travelled at 4mph, hence 24 miles.
IF no level walking, then uphill is 12 miles @ 3mph, so 4 hours to reach top: 7 o'clock. Since there was at least one step on level(!) at speed 4mph, then top reached a bit faster, hence between 6:30 and 7.
Cute li'l headacher Rog!

1. Ok. One more try.......and then I'm Out for the Count
Sometimes lost is where you need to be. Just because you don't know your direction doesn't mean you don't have one.

#6: the marbles. Give 'em weights of 2 and 3 units: r2,r3,b2,b3,y2,y3; if unknown: r?,b?,y?
Compare r? b? to r? y? (2 of 1 color, 1 each of other color...pick your poison!)
IF EVEN; only total weight of 5 is possible on each side; 2 possibilities: r3 b2 : r2 y3 ; left: b3 y2 [1] r2 b3 : r3 y2 ; left: b2 y3 [2] Compare the 2 that are left: [1] b? heavier, so this one is b3, leaving b2 on scale; others forced as shown [2] y? heavier, so this one is y3, leaving y2 on scale; others forced as shown
IF LEFT SIDE HEAVY; 3 possibilities: r3 b3 : r2 y3 ; left: b2 y2 [1] r3 b3 : r2 y2 ; left: b2 y3 [2] r3 b2 : r2 y2 ; left: b3 y3 [3] Compare the b? and y? on scale to the 2 that are left: [1] b3 y3 > b2 y2 (6 : 4) [2] b3 y2 = b2 y3 (5 : 5) [3] b2 y2 < b3 y3 (4 : 6) Since the 3 cases are different, then each case is forced as shown.
IF RIGHT SIDE heavy; 3 possibilities: r2 b3 : r3 y3 ; left: b2 y2 [1] r2 b2 : r3 y3 ; left: b3 y2 [2] r3 b2 : r3 y2 ; left: b3 y3 [3] Compare the b? and y? on scale to the 2 that are left: [1] b3 y3 > b2 y2 (6 : 4) [2] b2 y3 = b3 y2 (5 : 5) [3] b2 y2 < b3 y3 (4 : 6) Since the 3 cases are different, then each case is forced as shown.
A real "twister", Rog...was sure it couldn't be done!

I'm thinking it's about 9.5 feet, or the circumference of the roller. Length of Cue's pool table in basement?

Yes, manxman! Goes contrary to what you think is the obvious (9.2), but if you imagine the centre of the rollers being stationary, then the slab goes 9.4 one way, and the ground goes 9.4 the other way. So the plank moves approx 18.4 in relation to the ground.
