Here are 25 aptitude-based questions along with their answers:
Numerical Aptitude:
1. Question: A train travels 360 miles in 3 hours. What is its average speed in miles per hour?
Answer: Average speed = Total distance / Total time = 360 miles / 3 hours = 120 miles/hour.
2. Question: If the cost of 8 pencils and 5 erasers is $43, and the cost of 5 pencils and 8 erasers is $41, find the cost of one pencil and one eraser.
Answer: Let the cost of one pencil be x and one eraser be y.
8x + 5y = 43, and 5x + 8y = 41. Solving these equations gives x = $3 and y = $4.
3. Question: If 20% of a number is 40, what is 30% of that number?
Answer: Let the number be x.
20% of x = 40, then x = 40 / 0.20 = 200. So, 30% of 200 = 0.30 * 200 = 60.
4. Question: A car travels 150 km in 3 hours. What is its speed in meters per second?
Answer: Convert km to meters: 150 km = 150,000 meters. Speed = Distance / Time = 150,000 meters / 3 hours = 50,000 meters/hour. Converting to meters/second = 50,000 / 3600 = 13.89 m/s.
5. Question: If 8 workers can build 2 houses in 6 days, how many workers are needed to build 12 houses in 18 days?
Answer: Workers * Days * Houses = Constant. So, 8 * 6 * 2 = 12 * 18 * x. Solving for x gives x = 1 worker.
Logical Reasoning:
6. Question: If all cats are mammals and some mammals are dogs, can we conclude that some cats are dogs?
Answer: No, we cannot conclude that some cats are dogs. The given statements do not provide enough information to make that inference.
7. Question: A clock is hanging on a wall. How many times does the minute hand overlap the hour hand in a day?
Answer: The minute hand overlaps the hour hand 22 times in a day.
8. Question: If 5 people can paint a house in 6 days, how many days will it take 3 people to paint the same house?
Answer: More people, fewer days. So, 3 people will take more days. Using the formula People * Days = Constant, 5 * 6 = 3 * x. Solving for x gives x = 10 days.
9. Question: Which number is the odd one out: 4, 9, 16, 25, 36?
Answer: 36 is the odd one out because it is a perfect square of 6, while the others are perfect squares of 2, 3, 4, and 5.
10. Question: If 4 people can eat 8 pizzas in 6 hours, how many pizzas can 6 people eat in 4 hours?
Answer: More people, more pizzas. Using the formula People * Hours * Pizzas = Constant, 4 * 6 * 8 = 6 * 4 * x. Solving for x gives x = 8 pizzas.
