1. Puzzle
Find detective coin from stack
Problem approach
Divide the coins in 3 parts i.e. group A of 3 coins, group B of 3 coins and group C of 2 coins.
1st weighing — weigh A and B against each other. If balance scale is straight that means fake coins is in group C otherwise A/B on which side scale is up.
2nd weighing — If fake coins is in group C as inference from 1st weighing, then weigh 2 voins against each other and find the lighter fake coin. If fake coins is A/B, weigh any two coin from that group. If scale is balanced then the third coin is fake, otherwise whichever showing lighter on scale.
For 3 weighing, make pair of 4 and followed by pair of 2 for the lighter group. At last compare the last 2 coins to find lighter coin.
8 → 4 →2 →1
