Let us say there are two natural numbers "L" and "R".
We performed eight operations on these two numbers as
Step-1: L = R
Step-2: L x L = R x L
Step-3: L^2 - R^2 = LR - R^2
Step-4: (L + R)( L - R) = R(L - R)
Step-5: L + R = R
Step-6: R + R = R
Step-7: 2R = R
Step- 8: 2 = 1
What is wrong here?
Step5 is Wrong.
We divided the two sides by (L-R).Since L = R which indicates that (L - R) = 0 and we cannot divide by zero.
If,
29 - 1 = 30
9 - 1 = 10
14 - 1 = 15
Based on similar logic, Can you prove that the below algebraic equation is true?
11 - 1 = 10 ?
XI - I = X
Remove I (Roman equivalent of number 1) from the LHS, you will the get the number on the RHS.
29 - 1 = 30
XXIX - I = XXX
14 - 1 = 15
XIV - I = XV
9 - 1 =10
IX - I = X
Similarly,
11 - 1 = 10
XI - I = X
Snow and Tyrion are two mad logicians and loves betting.They placed 11 Candies at the table and designed a small betting game, in which both of them need to eat Candies turn by turn with the following rules:Rule1: One need to eat at least one candy.Rule2: One cannot eat more than 5 candies.The one that eats last candy will loose.Snow won the toss and need to start.How many candies must Snow ear in order to make sure that he won the bet?
Snow eats 4 candies
How many candies Tyrion eats, Snow needs to make sure that only 1 candy is left after his turn, So Tyrion needs to eat the last candy.
Example:
If Tyrion picks 1, Snow picks 5
If Tyrion picks 2, Snow picks 4
....
...
If Tyrion picks 5, Snow picks 1

Sixteen nodes are shown below and you need to connect them based on the following rule: Every node can be connected to the number of nodes inside them, i.e. the first node there is a value of 1 which indicates that the first node can connect to exactly one node only.Can you do it?
It can be done as illustrated below.
