Logical Reasoning Practice Test

Explanation
The value of ADA can be determined by looking at the pattern established by the given examples. Each letter is assigned a numerical value based on its position in the alphabet. For example, A is 1, B is 2, C is 3, and so on. In the given examples, ADD is equal to 9, which means A = 1, D = 4, and D = 4. Similarly, BAD is equal to 7, which means B = 2, A = 1, and D = 4. CAD is equal to 8, which means C = 3, A = 1, and D = 4. Therefore, the value of ADA can be calculated as A = 1, D = 4, and A = 1, which adds up to 6.

Explanation
The value of each letter is determined by its position in the alphabet, starting with A = 1, B = 2, C = 3, and so on. To find the value of BABBAGE, we add up the values of each letter: B (2) + A (1) + B (2) + B (2) + A (1) + G (7) + E (5) = 20. Therefore, the value of BABBAGE is 20. Since 20 is not one of the given answer choices, the correct answer must be "None of these".

Explanation
The series follows a pattern where each letter is alphabetically increasing by one, except for the missing letter. The letters in the series are A, C, F, ?, and O. The missing letter should be alphabetically increasing by one from F, which is G. However, G is not one of the options provided. Therefore, the missing letter must be the next letter after G, which is H.

Explanation
Based on the given information, we can determine that Athos has a red herring and Portos has a white dog. It is also mentioned that Portos has a neighbor with a red door. Since Athos is the only one left, it can be inferred that Athos is the one with the red door. Therefore, the correct answer is Athos.

Explanation
The letters in the series are arranged in alphabetical order, but in a reverse pattern. The missing letter should be the next letter in the reverse alphabetical order, which is "s".

Explanation
The series follows a pattern where each letter is the reverse of its corresponding position in the alphabet. The missing letter should be the reverse of the 20th letter in the alphabet, which is "t".

Explanation
The code for each letter in the word "JAVA" is obtained by shifting the letter 2 positions to the right in the alphabet. Applying the same logic, the code for each letter in the word "BASIC" would be obtained by shifting the letter 2 positions to the right. Starting with the letter "B" and shifting 2 positions to the right gives us the letter "D". Continuing this pattern for each letter in the word "BASIC" gives us the code "DCUKE". Therefore, the correct answer is "DCUKE".

Explanation
The code for PHP is QLY. To determine the code for SQL, we can compare the positions of the corresponding letters in the alphabet. The first letter in PHP is P, which is the 16th letter in the alphabet. The corresponding letter in the code, Q, is the 17th letter in the alphabet. Similarly, the second letter in PHP is H, which is the 8th letter in the alphabet, and the corresponding letter in the code, L, is the 12th letter in the alphabet. Applying the same logic, the code for SQL would be TUU, as S is the 19th letter in the alphabet and Q is the 17th letter, and L is the 12th letter while U is the 21st letter.

Explanation
Mr Bumpem and Mr Parker must both have morning appointments because Mr Bumpem is only available on Wednesday and Mr Parker can make any time on a Saturday. Since Mr Bumpem is only available on Wednesday, the only available time for him is in the morning. Similarly, since Mr Parker can make any time on a Saturday, he can also choose to have a morning appointment. Therefore, both Mr Bumpem and Mr Parker must have morning appointments.

Explanation
The coding pattern for the word "FORTRAN" in the given alphabet is obtained by shifting each letter one position to the right. Applying the same pattern to the word "PASCAL" gives the code "QBTDAM."
Here's the breakdown:
F becomes G
O becomes P
R becomes S
T becomes U
R becomes S
A becomes B
N becomes O
Therefore, the code for "PASCAL" is "QBTDAM."
