Cryptarithmetic is the science and art of creating and solving cryptarithms.
A Cryptarithmetic is a genre of mathematical puzzle in which the digits are replaced by letters of the alphabet or other symbols.
The invention of Cryptarithmetic has been ascribed to ancient China. This art was originally known as letter arithmetic or verbal arithmetic. In India, during the Middle Ages, were developed the arithmetical restorations or “skeletons” a type of cryptarithms in which most or all of the digits have been replaced by asterisks.
The world’s best-known alphametic puzzle is undoubtedlySEND + MORE = MONEY. It was created by H. E. Dudeney and first published in the July 1924 issue of Strand Magazine associated with the story of a kidnapper’s ransom demand.
Importance of Cryptarithmetic in Elitmus
Solving a Cryptarithmetic Problem will take nearly 10-12 minutes in exam. If you are able to solve puzzle, then you can easily answer the 3 question based on crypt within 2 minutes. Questions are only based on basic mathematics like, find the value of A+B+C , or 2A+C or triangle related questions.
For scoring a higher percentile in problem solving section, you need to solve 5-7 questions. If you are able to solve crypt, then you only need to solve 3-4 questions more from the remaining 17 questions.
