Quantitative Aptitude

Key Patterns:

Algebraic Formulas: Problems involving quadratic equations, inequalities, and simplification.
Geometry: Questions on properties of shapes, perimeter, area, and volume calculations.
Arithmetic: Speed, distance and time, work and time, and profit and loss calculations.

Sample Questions:

Algebra:
- Question: If $x + \frac{1}{x} = 3$ $x$ $+$ $x$ $1$ $$ $=$ $3$ , what is $x^{2} + \frac{1}{x^{2}}$ $x$ $2$ $+$ $x$ $2$ $1$ $$ ?
- Answer: Use the identity $x^{2} + \frac{1}{x^{2}} = (x + \frac{1}{x})^{2} - 2$ $x$ $2$ $+$ $x$ $2$ $1$ $$ $=$ $($ $x$ $+$ $x$ $1$ $$ $)$ $2$ $-$ $2$ . Thus, it becomes $3^{2} - 2 = 7$ $3$ $2$ $-$ $2$ $=$ $7$ .
Geometry:
- Question: A rectangle has a length of 8 cm more than its width. If the perimeter is 64 cm, find the area of the rectangle.
- Answer: Let the width be $w$ $w$ . Then length $l = w + 8$ $l$ $=$ $w$ $+$ $8$ . The perimeter $2 (l + w) = 64$ $2$ $($ $l$ $+$ $w$ $)$ $=$ $64$ . Solve for $w$ $w$ and $l$ $l$ , then find area $l \times w$ $l$ $\times$ $w$ .
Arithmetic:
- Question: A car travels from point A to B at 60 km/h and returns at 40 km/h. What is the average speed for the entire journey?
- Answer: The average speed is $\frac{2 \times 60 \times 40}{60 + 40} = 48$ $60$ $+$ $40$ $2$ $\times$ $60$ $\times$ $40$ $$ $=$ $48$ km/h.

Logical Reasoning

Key Patterns:

Pattern Identification: Determining the next in a sequence.
Arrangement Puzzles: Solving problems based on a set of conditions.
Deductions: Deriving conclusions from given premises.

Sample Questions:

Pattern Identification:
- Question: What comes next in the sequence: 2, 6, 12, 20, 30, ?
- Answer: The pattern increases by consecutive even numbers: 4, 6, 8, 10, so next is 30 + 12 = 42.
Arrangement Puzzles:
- Question: Five people are sitting in a row. John is to the left of Amy but to the right of Peter. If Mike is to the left of Peter, who is at the far right?
- Answer: Amy, as she is to the right of everyone mentioned.
Deductions:
- Question: All dogs are animals. All animals have four legs. Therefore, ?
- Answer: All dogs have four legs.

Verbal Ability

Key Patterns:

Synonyms and Antonyms: Recognizing similar and opposite words.
Sentence Correction: Identifying grammatical errors.
Reading Comprehension: Answering questions based on a given passage.

Sample Questions:

Synonyms:
- Question: Find a synonym for "elucidate".
- Answer: Clarify.
Sentence Correction:
- Question: Correct the sentence: "He don't like playing basketball."
- Answer: "He doesn't like playing basketball."
Reading Comprehension:
- Question: (Based on a short passage) What is the main idea of the passage?
- Answer: Answers will vary depending on the passage provided.

Technical Questions

Key Patterns:

Algorithm Analysis: Understanding and evaluating algorithms.
Data Structures: Questions on arrays, linked lists, trees, etc.
Debugging: Identifying errors in code snippets.

Sample Questions:

Algorithm Analysis:
- Question: What is the time complexity of binary search?
- Answer: $O (\log n)$ $O$ $($ $log$ $n$ $)$ .
Data Structures:
- Question: What data structure would best manage a list of priorities?
- Answer: A priority queue.
Debugging:
- Question: Identify the error in the code: int a = 10; if (a = 11) { printf("Eleven"); }
- Answer: The if statement uses assignment (=) instead of comparison (==).

These patterns and questions should give you a comprehensive overview to prepare for the various sections of an aptitude test for entry-level developer positions. Practice these types of questions regularly to enhance your problem-solving speed and accuracy.
