Don't worry Patrick. I was only joking with you. However, there is an important point within my joke. I am guessing that you are maybe one of the younger contributors here who has only learned metric units of measurement. The practical application of my (lame?) joke is actually very real. There are still large chunks of this world that insist on using imperial measurements such as pounds and miles. Equally, if you follow my example through, you will see that currency conversion also becomes a factor. The lesson is that the real world contains a myriad of situations where the ability to translate readily from one system to another AND to have some basic grasp of the relative scale of measurements can be a huge benefit. Let me give you a genuine example of how this can be useful.
For instance, I am a driver: I live in the UK. We now sell our petrol (gas) in litres, but we are still fixated on gallons and many older drivers still only think in gallons. I know that my car does about 35 miles per gallon (4.54 litres) and the price of the fuel is just over 90 pence per litre. In broad terms, this gives me a cost of 11p per mile. Now, I also travel frequently to the Philippines, where gas is priced in Pesos and sold in litres. The car only records distance travelled in kilometres. I know that the car does 10km per litre and that the cost is 30 Pesos per litre. The conversion rate of UK pound to Peso varies between about 90 and 100 Pesos to the pound.
Now, I can spend a long while working out exactly what my cost per distance travelled is, but, by having a good awareness of relative scale, I don't need to do that. Indeed, when I am driving, I am concentrating on driving, not on maths! Understanding the relative scales, tells me instantly that the price per litre in the Philippines is only 1/3 of the price in the UK. Hence, as long as the car in the Philippines has no major mechanical problem, I know that it is considerably cheaper to drive there than in the UK.
So, let's return to the apples:
In ganesh's problem, I get 100 apples (at 100g each) for 96 cents. 1 lousy cent each! I am proposing to sell you one pound weight for one pound Sterling. Say £1 = $1.70, then I am offering you approximately 4 1/2 apples for $1.70 when they only cost me 4 cents. In other words, I am ripping you off big time.
So, if you are still studying, then study well and learn the system you are being taught, but don't forget WHY mathematics is important. Understanding relative scale and the art of approxmation are vital skills in everyday life.
Don't worry Tigs, just testing Krassi's knowledge of Russian. Well, he started it!!
I agree with Patrick. Any serious visitor would surely be prepared to register. Take a look at the user list: two-thirds of all registered users have never even made a post. Of the remainder, all but about 5% only make the odd couple of posts. That certainly suggests that registration is easy enough for the casual visitor (or silent spectator). I can't see that it would be a major hindrance to anyone's learning, but it would definitely help those already here.

Oчен хорошо мой друг! Молодец!!
As a purely optimistic step, I contacted this company today. Believe it or not, they actually have an anti-spam hotline (which, of course, is just an admission that they use spam in the first place). I explained that this forum has many young members who are highly unlikely to require their products and that, as well as not getting any sales, they are disrupting an educational site. Let's see if they have a conscience???
I feel really bad now, cos I didn't see it as a pink bunny at all....... actually I saw it as something rather less flattering.... Um, err, I thought it was a little pink pig! Now that I've seen the whole thing and readjused my perspective, I can't see the pig anymore!!
Really sorry about that, bun!
OK, the first of the examples refers to Monday, Tuesday, Wednesday etc. I.e., these examples are not mathematical, but rely on lateral thought to make a conection with a sequence that is "familiar" in its normally occurring form. These 3 examples are the ones you would see most often, but sometimes you may get something really obscure like HHLBBC... (the periodic table of the elements: Hydrogen, Helium etc)
I suggest you focus on the 3rd category!
A clue of sorts:
In solving letter sequences, there are usually 3 basic questions to ask:
1. Is there a mathematical progression? (eg, move 4 letters through the alphabet, then back two etc)
2. Is there a sequence based on initial letters of something occurring in general life, not mathematics? (MTWTFSS, OTTFFSS, JFMAMJJ)
3. Is there an intrinsic quality to the letters themselves that has nothing to do with the above?
4.
Patrick, if I bought the apples in question 1 at the correct price and, assuming the average apple weighs 100g, then sold you a pound for one pound, would you think it was a good deal for you or for me? How much profit or loss would I make?
Cool! It actually works retrospectively!
Thank you lady & gentleperson! I hope to return later with a brand new personality!
Where does everybody find their avatars?
Being of the "more mature" variety, I have grown up with computers being a business tool, not a fun thing, so things that may be instinctive to the younger ones are not immediately obvious to me! I have tried a quick search, but am finding it very difficult to find anything vaguely amusing that fits within the requirements of 60 x 60 and max 10Kb.
Any suggestions

JLFM: Sorry, I deleted your amendment to my post! It made it look like I had named a town! I guess my use of old-fashioned colloquial language to describe nothing more specific than a country may have been unfamiliar and could have appeared that way. Sorry if I caused confusion/concern.
Alas, it is more a tribute to memory than to puzzle-solving ability. I just had a flash of inspiration and remembered my maths teacher from 1978 who had a fascination for this kind of puzzle. He had set us a very similar teaser that took us weeks to crack (and with more than one or two clues!).
Is it time to give a clue on this one? I must say, the logic is one of the more obcure relationships.

Many congrats espeon, but please be careful with your personal details! Good luck for the next stage of your school career.
May I say how pleasant this forum seems to be! Everybody seems to talk to each other as human beings with no sign of flame or rudeness. I think I may stay a while!!
Depends on your method of calculating profit margin. Most sales organisations calculate on selling price, not on cost price. Hence,
The letter after E would be X
Looks like it was a lucky guess prompted by the apparent relative positioning of B, C, D! What about it, guys?
