2519


LCM – HCF  = 2520 -1 


Other approach
The number has to end in 9.
Looked brute force for small numbers.
59 and 119 were promising, but no cigar.

Then looked for agreement among
39 + multiples of 40,
69 + multiples of 70 and
89 + multiples of 90
Smallest one was 2519.

The spirit lies behind Door D.

If the spirit is behind Door A, then both B and D are true.

If the spirit is behind Door B, then both A and D are true.

If the spirit is behind Door C, then A, C, and D are all true.

If the spirit is behind Door D, then the statements on all the doors are false, except for that on Door B. This matches the rules, and therefore, the resort hotel spirit lurks behind Door D.

Set the first switches on for abt 10min, and then switch on the second switch and then enter the room.
Three cases are possible
1.Bulb is on => second switch is the ans
2.Bulb is off and on touching bulb , you will find bulb to be warm
=>1st switch is the ans.
3.Bulb is off and on touching second bulb , you will find bulb to be normal(not warm)
=>3rd bulb is the ans.

Jeff Killed Mike
1. Jack is not the murderer, because he is the brother of the murderer.
2. Dan can’t be the murderer since he ran a marathon, and the murderer recently had his leg amputated, and wouldn’t be running a marathon of any magnitude that quickly.
3. Ben is not the murderer if he just met Jack, since Jack and the murderer grew up together.
4. This leaves Jeff and Mike.

Since Jeff is still alive (he wants to install a new computer next week, present tense) he must be the murderer. Mike also didn’t grow up with Jack. It has been determined that Jack, Dan and Jeff are all alive. Ben must also be alive since Jeff plans to install Ben’s computer next week. This means that Jeff killed Mike.

3 1 2 2 1 1
1 3 1 1 2 2 2 1

Line 1 is ‘Two ones’ (2 1)
Line 2 then becomes ‘One two, and one one’ (1 2 1 1)
Line 3 therefore is ‘One one, one two and two ones’ (1 1 1 2 2 1)
Line 4 is ‘Three ones, two twos and one one’ (3 1 2 2 1 1)
Line 5 is ‘One three, one one, two twos and two ones’ (1 3 1 1 2 2 1 1)

‘Didn’t you say that you sold your well to this farmer?’ Birbal asked the neighbour. ‘So, the well belongs to him now, but you have kept your water in his well. Is that right? Well, in that case you will have to pay him a rent or take your water out at once.'<br>The neighbour realized that he was outwitted. He quickly apologised and gave up his claim.”

Each word rhymes with its numeric position in the list. (e.g. ‘gun’ rhymes with ‘one’, etc.)

Starting with 1 lemons in a bag, each bag contains double the number of lemons as the previous bag. ie 1,2,4,8,16,32,64,128,256,512. That way whatever number of lemons I would ask for you would just add up the bags to equal the number asked.

When you mix bleach and ammonia [found in most cleaning products] it creates a deadly gas that can kill.
