Really stretching the numbers to fit the answer said: then write down further figures with the leading digits removed: 0p, 5p, 47p, 6p, 0p (total 58p) What I really don't get is the justification of this bit..? surely '16' is '16' not '16+6'? I can kind of accept the rest of it.. then again write down further figures with another leading digit removed: 0p, 0p, 7p, 0p, 0p (total 7p) the 'official' answer (according to the Telegraph) seems even weirder: "Two pounds is 200p plus 2p (two p) [no further justiication given] and 1p (at the beginning of 'pounds') makes 203p 25p: 25p plus 5p and 1p (the 'p' in the question) = 31p £1.47 = 147p 16p: 16p plus 6p and 1p = 23p Fifty pence: 50p plus 50p (fifty p, a shortening of pence), 1p (reference to pence) and 1p (from the 'p') = 102p 203+31+147+23+102 = 506 | ||

Really stretching the numbers to fit the answer said: A convoluted way of looking at it Wll done Richard - that's about it. ITV have now published the official result. Bear in mind that at one stage during the broadcast this would have earnt you £30k:ITV explained that the answer could be reached by breaking up the figures in the list to find all the references to pence. Thus: -Two pounds is 200p plus 2p (two p) and 1p (p at the beginning of 'pounds') which makes 203p -25p: 25p plus 5p and 1p (the p symbol) = 31p £1.47 = 147p -6p: 16p plus 6p and 1p (p again) = 23p -Fifty pence: 50p plus 50p (fifty p, a shortening of pence), 1p (reference to pence) and 1p (p only) = 102p -Adding 203p, 31p, 147p, 23p and 102p gives a total of 506p | ||

Simon said: As this is crosswords and other puzzles, here's one from ITVPlay, currently subject to inevstigation by Ofcom: A convoluted way of looking at itA graphic asked viewers to "Add the pence" from "Two pounds, 25p, £1.47, 16p, Fifty pence". More than three hours later, the host announced the answer was 506 and that no-one had won. No method was given. ITV has denied the problem was particularly complex but has not commented further. £2 25p £1.47 16p 50p write them in pence: 200p, 25p, 147p, 16p, 50p (total 438p) then write down further figures with the leading digits removed: 0p, 5p, 47p, 6p, 0p (total 58p) then again write down further figures with another leading digit removed: 0p, 0p, 7p, 0p, 0p (total 7p) The sum of these three subtotals = 503p Now look back at the question. Add the pence: Two pounds, 25p, £1.47, 16p. 50pence There are 3 p or pence listed. Add this to the toal that we already had. 506p - simple. | ||

The Times Online said: ..a puzzle intended for an early-hours viewing audience of drunks and poor sleepers... Good to see the Times has so much respect for its readership! ... A reader of The Times said [about the show] ... As for how you get to 506.. Add two pounds worth of old money (2 * 20 shillings/pounds * 12 pence/shilling) to the other numbers in pence = 718 Subtract the 75p you spent calling in your answer = 643 This leaves you £1.37, which is taken into account by the 40.77 minutes you spent complaining to ITVPlay, or the 19.57 minutes complaining to OFCOM = 506p. Obvious. | ||

Fabulous Ming's hot coach of term: number one for two thousand and seven? (7, 6, 6) I'll take the stony silence as a request for hints, so here you go:1) No specialist knowledge is required; anyone at the club (or not at the club) could solve this. 2) Unlike the clue, the answer has nothing to do with rowing. 3) If I'm honest, 'Fabulous' wasn't a great choice of word. It enhances the surface reading but is a bit dubious in the cryptic reading. Better would have been "Staggering Ming's...". | ||

gf said: Hmm... within rally co-drivers' pacenotes, there are various four-letter words which might somehow be applicable ("bump", "fast", "easy"...) but I can't find a combination which sits well with the rest of the clue. I'm baffled by this. The only two interpretations I can come up with are:1) The definition is 'A rallying cry', and the answer is formed from two shorter words (total 8 letters) meaning 'leader', e.g. 'king', 'CO', etc. 2) The whole clue is a cryptic definition, possibly punning on 'rally' meaning 'to drive a car in a rally race' or 'to get better' or 'to demonstrate/protest', and with 'the two leaders' possibly referring to the double headship. | ||

I guess one of the words is probably 'head'?A couple of people have asked for an explanation of the (6, 8) clue below, so here it is: 'First and Third decked in gold' = 'gold' with the first and third letters removed ('decked') = OD so: 'First and Third decked in gold and blue remarkably' = OD and BLUE 'remarkably' (anagrammed) = DOUBLE 'crown' = HEAD 'end of Bumps' = S 'with it' = HIP (as in 'trendy') and the whole clue is also the definition. | ||

Rowing (27) is obviously pretty low, but then this is mainly because it is sub-categorised and thus flexible enough to have something approaching a fair system for any age. Still, there must be something lower. Women's gymnastics maybe (bet that'd be about 16....)? In swimming the qualification age for 'Masters' events is 25. I don't know of anything lower than this. | ||

jpd said: Is the right answer. You could also start on any circle which isIf we assume the small area around the South pole is flat, our start point would be any point on the circle which is 1 + 1 / (2 * pi) miles North of the South pole. Where else could I be? 1 + 1 / (2n*pi) miles north of the South pole. | ||

jpd said: Is that inclusive or exclusive? If it doesn't include 1, then I think 4&13 work.Peter is told the product, 52 Simon is told the sum, 17 52's factors are; 2&26, 4&13 Simon knows that Peter couldn't tell what the numbers were just from the product. If Simon was told 28, then one of the possibilities for 28 are 5&23, but the product of 5&23 is 115 (which can be made in no other way) - so if Simon was told 28, then he couldn't know that Peter couldn't tell what the numbers were. Therefore Simon was told the sum 17. Peter now knows what the numbers are. The possiblities for a sum of 17 are 2&15 (product 30), 3&14 (42), 4&13 (52), 5&12 (60), 6&11(66), 7&10(70), 8&9(72) product 30 gives 2&15(sum 17), 3&10(13), 5&6(11) Only a sum of 13 would be eliminated by Peter when told that Simon already knew that Peter couldn't tell what the numbers were (13 can also be 2&11 whose product 22 can only be formed in 1 way), leaving 2 remaining possibilities therefore Peter can't have worked out the right answer. Therefore it's not 2&15 as the answer. The same argument can be used for 42,60,66,70 and 72, but not for 52. Therefore Simon will also be able to work out that the numbers must be 4&13 | ||
