We have listed some important quantitative questions and their answers for the students:

A pair of shoes originally costs ₹2,000 and is on sale for 15% off. What is the sale price?

**Answer:** Sale price = Original price - (15% of Original price)

= ₹2,000 - (0.15 × ₹2,000)

= ₹2,000 - ₹300

= **₹1,700**

In a class, the ratio of boys to girls is 5:3. If there are 40 boys, how many girls are there in the class?

**Answer:** Let the number of girls be x.

The ratio of boys to girls is 5/3, so:

40/x = 5/3 = 5x = 120 = x = 24

There are **24 girls** in the class.

What is the simple interest on a principal amount of ₹10,000 at an annual interest rate of 7% for 4 years?

Answer: Simple Interest (SI) = 𝑃 × 𝑟 × 𝑡

where,

P is the principal,

r is the rate of interest, and

t is time in years.

SI= 10,000 × 0.07 × 4 = 2,800

The simple interest is **₹2,800**.

If a person can complete a task in 8 hours, how much of the task can they complete in 2 hours?

Answer: Work done in 1 hour = 1/8 of the task

Work done in 2 hours = 2 x 1/8 = 2/8 = 1/4 of the task

So, the person can complete **1/4 of the task** in 2 hours.

Find the average of the following numbers: 10, 20, 30, 40, and 50.

Answer: Average = Sum of numbers/Number of values

Sum = 10 + 20 + 30 + 40 + 50 = 150

Number of values = 5

Average = 150/5 = 30

The average is 30.

What is the difference in the place value of 5 in the numeral 754853?

Answer: The digit 5 has two place values in the numeral, 5 x 10^{5} = 50,000 and 5 x 10^{1} = 50.

∴ Required difference = 50000 - 50 = 49950

If January 1, 1996, was Monday, what day of the week was January 1, 1997?

Answer: The year 1996 is divisible by 4, so it is a leap year with 2 odd days.

As per the question, the first day of the year 1996 was Monday, so the first day of the year 1997 must be two days after Monday. So, it was **Wednesday**.

The resource on quantitative aptitude questions and answers serves as an invaluable tool for students and professionals preparing for various competitive exams and placement tests. It encompasses a comprehensive range of topics, ensuring that learners can enhance their quantitative skills and logical reasoning abilities. This article equips individuals with the necessary tools to tackle complex mathematical problems effectively. Therefore, engaging with these quantitative aptitude questions is essential for success in both academic pursuits and career advancements. It helps foster a solid foundation for future challenges in various fields.

To prepare for quantitative aptitude effectively, students must develop a keen understanding of the syllabus and familiarise themselves with key topics such as percentages, ratios, averages, and time and work. They must gather relevant study materials, including books and online resources tailored to your target exam. Regular practice is essential, so students should solve a variety of problems daily to enhance their skills and speed. Memorising important formulas and learning shortcut techniques will also aid in quicker calculations.

Here is an example of an aptitude question with answer:

A pipe can fill a tank in 6 hours, and another pipe can empty the tank in 12 hours. If both pipes are opened at the same time, how long will it take to fill the tank?

Part of the tank filled in one hour = 1/6

Calculate the part of the tank emptied in one hour by the emptying pipe:

Part of the tank emptied in one hour = 1/12

Net part of the tank filled in one hour = 1/6 - 1/12

= 2/12 - 1/12 = 1/12

Therefore, 1/12 part of the tank can be filled in one hour. Since 1/12 of the tank is filled in one hour, the entire tank will be filled in 12 hours.

A pipe can fill a tank in 6 hours, and another pipe can empty the tank in 12 hours. If both pipes are opened at the same time, how long will it take to fill the tank?

Part of the tank filled in one hour = 1/6

Calculate the part of the tank emptied in one hour by the emptying pipe:

Part of the tank emptied in one hour = 1/12

Net part of the tank filled in one hour = 1/6 - 1/12

= 2/12 - 1/12 = 1/12

Therefore, 1/12 part of the tank can be filled in one hour. Since 1/12 of the tank is filled in one hour, the entire tank will be filled in 12 hours.

The quantitative aptitude section is not only challenging but also lengthy, requiring extensive calculations to arrive at the final answer. To achieve higher scores, candidates must improve their speed in solving these problems.
