In a word of riddles called Briddles, 9 numbers from 1 - 9 want to reach to the other side of the river. Since its a world of riddles, therefore, there are some rules:
Rule-1: Maximum 3 numbers can cross at a time.
Rule-2: River cannot sail on its own.
Rule-3: The sum of numbers crossing at a time must be a square number.
You need to plan trips such that minimum trips are needed for all numbers to cross.
7 Trips
Send 2+5+9 = 16
Bring back 9
Send 3+4+9 = 16
Bring back 9
Send 1+7+8 = 16
Bring back 1
Send 1+6+9 = 16
With the help clues provided in the image, can you find the 5 digit key?
One of 57620 or 57628 is the key
Clue-1: 79314
7 is the only part of the key and is in the wrong position
Clue-2: 95643
6 is in the appropriate position while 5 is not
Clue-3: 57319
Both 5 and 7 are in the appropriate position
Sum Clue: A + B + C + D + E = D*10 + E
CaseA - 57620
5 + 7 + 6 + 2 + 0 = 2 * 10 + 0
20 = 20
CaseB - 57628
5 + 7 + 6 + 2 + 8 = 2 * 10 + 8
28 = 28
Two cowboys played a strange deathmatch.
DeathMatch Rules:
1. They both need to fire 23 bullets in total.
2. They will shoot one by one.
3. They can shoot once or twice in their chance.
4. The one that shoots last i.e 23rd shot needs to fire bullets at himself.
If you are one of the cowboys, will you shoot first or second?
Shoot 1st.
Explanation:
> You Shoot once.
> Then shot opposite of what the other cowboy shoot i.e if other cowboy shots 2 times, you shot once and vice versa.
> After 15 shots, bullet remaining will be 23 - 1 - 7(2+1) = 1
> The other cowboy need to fire the last bullet
By deducing the logic used in the table below, can you find the missing number?
52
For 1st column: 26 - 4 = 22
For 2nd column:37 - 5 = 32
For 3rd column:48 - 6 = 42
Missing number
59 - 7 = 52
