Help with logic problems, just some notes they're all oyu need so i made them for you ;)
Use a DIAGRAM even if it doesn't really need one, it will help you imagine it, it's the next best ting to having the objects there in front of you!
All these hints will do is regulate what or how you think about the puzzle, this is the hardest bit of a logic puzzle, what you should be thinking about!
1.First lets work out the weight of a real bead and a fake one 10 beads each at 10g so each bag should weigh 100g except the fake weighs 90! We can only weigh once so we must use at least a bead from each bag (we'll do it like this for simplicity)
Well, if you put one of each bead in you will end up with a deficient of one, if you pt five of each a deficit of five! Hmm,(Extra hint:) but if I put one of each bag but 2 from one bag and the deficit is 2g then I know it came form the 2 beads :D think about it! And you'll get the answer...
2. Well one of them can see two hats so what's the best situation? He should be able to shout the answer out straight away! Another can see one hat but he also has an advantage, all he has to do is listening to check if the first one calls the answer out if not then he can work-out his hat by seeing the hat in front of his!
3. Anyone done UKMT? Well just work backwards with this one, set out 30 marks then go through it marking the colours!
4. Ah maths simple! Use algebra and the assumption that it's a perfect parallelogram, opposite sides and diagonals are congruent...
5. Learn how fuses work, especially the similarity between them and light bulbs (that’ll differentiate one bulb then with the nature of bulbs (what do light bulbs do!) and this you should be able to differentiate the other two! (Extra hint;) Why dont you take your bedroom bulb out and have a closer look?
6. EUREKA! Read about Archimedes and assume that the glass is a prism! Surface area times height! P.S. This give sthe exact volume!
I LOVE LOGIC PROBLEMS!
