Numbers: Alphametics- The Art of Numbers for CAT 2018
As CAT 2018 preparation starts heating up, I am going to flag the race with an oddball topic: Alphametics. What are alphametics or cryptarithms as they are also known?
Alphametics are number puzzles in basic arithmetic operations where digits are represented by alphabets. It is customary that different digits are represented by different alphabets. Why are alphametics relevant? Because they require a good knowledge of the properties of numbers and skill in working with them. Solving alphametics helps you quickly identify the solution to many problems which might otherwise require a good amount of time.
