Logical Reasoning

Step 1: Analyze the conditions.
- (I) A, P, and Z must be together. - (II) B cannot go with D or R, so B must go with others. - (III) E and Q must be together. - (IV) C and T must be together. - (V) D and P cannot go together, so P cannot go with D. - (VI) C cannot go with Q, meaning C and Q are not allowed together. Considering these conditions, the team with members A, B, P, Z, and S satisfies all the given conditions.

Final Answer:

Blood relation questions require careful interpretation of family relationships described in a statement. The best approach is to simplify the statement step-by-step and identify each relationship logically.
Step 1: Start with the innermost part of the sentence.
The statement says: Since the boy himself is speaking, the phrase "my father's only son" refers to the boy himself.
Step 2: Identify the next relation.
The sentence now becomes: Since the father's only son is the boy, the mother of the boy is simply his mother.
Step 3: Interpret the complete statement.
The girl is described as: The daughter of the boy's mother would be:

• Either the boy himself (if he were a girl) or
• His sister

Since the statement refers to a girl, the relationship must be:
Step 4: Final answer.

Concept:
Coding–decoding problems often involve shifting letters in the alphabet by a certain number of positions. To identify the pattern, we compare each letter of the original word with its corresponding coded letter and observe the alphabetical shifts.
Step 1: Write the given coding.
Now compare the alphabetical positions.
Step 2: Determine the letter shifts.
Thus, each letter is shifted forward by 5 positions in the alphabet.
Step 3: Apply the same rule to the word BEAT.

Step 4: Form the coded word.

Step 5: Select the correct option.

Concept:
In number series questions, we often identify patterns in the differences between consecutive numbers. Many series follow patterns such as increasing differences, multiplication patterns, or combinations of arithmetic operations. A useful strategy is to calculate the difference between consecutive terms to detect a pattern.
Step 1: Write the given series.

Step 2: Find the differences between consecutive numbers.
Thus, the differences are:
Step 3: Identify the pattern in the differences.
Each difference is double the previous one: Therefore, the next difference should be:
Step 4: Find the next term in the series.
Thus, the next number in the series is:
Step 5: Selecting the correct option.
Hence, the correct answer is:
