1) Which of the following types does the Cryptarithmetic problem belong to?
- Encryption Problem
- Constraint Satisfactory Problem
- Number problem
- All of the above
Correct answer: 4
All of the above
The Cryptarithmetic problem belongs to every type of mentioned problem: Encryption problem, Constraint satisfactory problem, as well as Number Problem.
2) Which of the following mentioned properties are valid for a Cryptarithmetic problem?
- A number 0-9 is assigned to a particular alphabet.
- Each different alphabet has a unique number.
- All the same alphabets have the same numbers.
- The numbers should satisfy all the operations that any normal number does.
Options:
- Only iv.
- All i., ii., iii. and iv.
- ii. and iv.
- None of the above
Correct answer: 2
All i., ii., iii. and iv.
All the mentioned properties are valid properties for a Cryptarithmetic problem.
3) Which of the mentioned point are not valid with respect to a Cryptarithmetic problem?
- Constraints should be taken care of while solving the problem
- The text is converted from readable format to non-readable format
- If numbers are not sufficient, we can use special symbols like $#@% to encrypt the text
- None of the above
Correct answer: 3
If numbers are not sufficient, we can use special symbols like $#@% to encrypt the text
There is no rule in the Cryptarithmetic problems regarding using the special numbers for encryption. We must encrypt the text using the numbers 0-9. Hence, this encryption method is limited to small length texts only.
4) Consider the following statement:
"The Cryptarithmetic problem in Artificial Intelligence is a type of encryption problem in which the written message in an alphabetical form which is easily readable and understandable is converted into a numeric form which is neither easily readable nor understandable."
By reading the above statement, what are the places where this technique can be applied?
- To share passwords
- To encode number plates of vehicles
- To encode their names by students while filling the answer sheet
- None of the above
Correct answer: 1
To share passwords
The Cryptarithmetic problem is an efficient way to share passwords. However, the other things mentioned do not require any encryption, so applying this technique there would be a waste of time.
5) Provide the answer for the following Cryptarithmetic problem:
"SEND MORE MONEY"
- S=12; E=5; N=6; D=8; M=1; O=0; R=8; Y=2
- S=9; E=5; N=6; D=7; M=1; O=0; R=8; Y=2
- S=5; E=5; N=6; D=7; M=1; O=0; R=8; Y=2
- S=9; E=5; N=9; D=7; M=1; O=0; R=8; Y=2
Correct answer: 2
S=9; E=5; N=6; D=7; M=1; O=0; R=8; Y=2
Cryptarithmetic problems should be solved, but here we can find the answer to this question through the options itself.
The first option has S=12 which exceeds 0-9 range.
The third option has the same value for S and E
The fourth option also has the same values for S and N
Therefore, the correct option is b.
