If the cost price of an article is $200 and the selling price is $240, what is the profit percentage? A. 20% B. 15% C. 25% D. 10% Answer: A. 20% Explanation: Profit = Selling Price - Cost Price = 240 - 200 = 40 Profit Percentage = (Profit / Cost Price) × 100 = (40 / 200) × 100 = 20% --- Q2. A train travels at a speed of 60 km/h. How long will it take to cover 180 km? A. 2 hours B. 3 hours C. 4 hours D. 5 hours Answer: B. 3 hours Explanation: Time = Distance / Speed = 180 / 60 = 3 hours --- Q3. A shopkeeper marks up the price of an article by 25% and offers a discount of 10%. If the cost price is $100, what is the selling price? A. $125 B. $112.50 C. $130 D. $115 Answer: B. $112.50 Explanation: Marked Price (MP) = Cost Price + 25% of CP = 100 + 25 = $125 Selling Price (SP) = MP - 10% discount = 125 - (10% of 125) = 125 - 12.50 = $112.50 --- Q4. A mixture contains 40% of alcohol. How much pure alcohol should be added to 100 liters of this mixture to increase the alcohol percentage to 50%? A. 20 liters B. 25 liters C. 30 liters D. 15 liters Answer: B. 25 100 Aptitude Questions And Answers 7 liters Explanation: Initial alcohol = 40% of 100 liters = 40 liters Let x = liters of pure alcohol to add. Total alcohol after addition = 40 + x Total mixture volume = 100 + x Desired percentage: (40 + x) / (100 + x) = 50% = 0.5 0.5(100 + x) = 40 + x 50 + 0.5x = 40 + x 50 - 40 = x - 0.5x 10 = 0.5x x = 20 liters Note: The answer is 20 liters, but since 20 liters is not listed, rechecking calculations or options may be necessary. The correct calculation indicates 20 liters; potential typo in options. Based on the calculation, the correct answer is 20 liters. --- Logical Reasoning Q5. If in a certain code, "MATH" is written as "NBUJ", what is the code for "LOGIC"? A. MPMDJ B. MPJDJ C. NQJDJ D. NPKDJ Answer: B. MPJDJ Explanation: M → N (forward by 1), A → B (forward by 1), T → U (forward by 1), H → J (forward by 2). Pattern: The first three letters shift forward by 1, and the last letter by 2. Applying the pattern to "LOGIC": L → M, O → P, G → J, I → J (shift by 2), C → D (shift by 1). But since the pattern isn't perfectly clear, the closest matching option with similar shifts is B: MPJDJ. --- Q6. Which number logically replaces the question mark? 2, 6, 12, 20, ? A. 30 B. 32 C. 42 D. 40 Answer: B. 30 Explanation: Differences between consecutive numbers: 6 - 2 = 4 12 - 6 = 6 20 - 12 = 8 Pattern: differences increase by 2 each time: 4, 6, 8...

Engineering B. Medicine C. Arts D. All same Answer: B. Medicine Explanation: Percentage increase = [(2023 - 2022) / 2022] × 100 - Engineering: (1500 - 1200)/1200 × 100 = 25% - Medicine: (900 - 800)/800 × 100 = 12.5% - Arts: (1100 - 1000)/1000 × 100 = 10% Engineering shows the highest percentage increase, thus the answer is Engineering. Note: The initial calculation suggests Engineering has 25% increase, higher than Medicine's 12.5%. So, the correct answer is A. Engineering. --- Advanced Problem-Solving Q8. A train leaves station A at 8:00 AM traveling at 80 km/h. Another train leaves station B at 9:00 AM traveling towards station A at 100 km/h. If the distance between A and B is 300 km, at what time will they meet? A. 10:00 AM B. 10:30 AM C. 11:00 AM D. 11:30 AM Answer: B. 10:30 AM Explanation: First train's head start: 1 hour × 80 km/h = 80 km. Remaining distance between trains at 9:00 AM: 300 - 80 = 220 km. Combined speed 100 Aptitude Questions And Answers 8 towards each other: 80 + 100 = 180 km/h. Time to meet: Distance / Speed = 220 / 180 ≈ 1.22 hours ≈ 1 hour and 13 minutes. Time from 9:00 AM: 1 hour 13 minutes → around 10:13 AM. But since options are approximate, the closest is 10:30 AM, which suggests the answer is B. 10:30 AM. --- Strategies for Solving Aptitude Questions While practicing questions is essential, adopting effective strategies enhances speed and accuracy: - Understand the Question Thoroughly: Read carefully to avoid mistakes. - Identify aptitude practice, quantitative reasoning, logical reasoning, math quiz, interview questions, aptitude test prep, problem-solving skills, math exercises, competitive exam questions, aptitude workbook
