Given : a random number doubled and 6 added , then halved then subtract the initial number
Result is 3
To Find : Whats the magic / logic behind this
Solution:
Let say any random number assumed is N
Double of Number = 2N
6 is added Hence 2N + 6
Number of Halved = (2N + 6)/2 = N + 3
N is subtracted hence N + 3 - N = 3
So Result is 3 , Independent of the value of N
