Question: Explain quantitative reasoning. What is the significance of quantitative reasoning? Explain the process of conducting quantitative reasoning.
Quantitative reasoning employs math and facts to solve real-world problems. However, problems having no connection with math can also be solved using quantitative reasoning. The article intends to convert real-world issues into math problems that can be solved faster. The book ‘How to Solve it’ by George Polya in 1945 is one of his most popular books.The book has been drafted in 17 languages, and over one million copies have been sold. The book is famous for its four fundamental rules of solving problems by applying quantitative reasoning. The rules are recognizing the problem, developing a plan, following the plan and looking back.
What is studied in quantitative reasoning?
In quantitative reasoning, students study how to recognize the problem, build a plan to solve it, implement the plan, and verify the results. The students can apply quantitative reasoning to solve their day-to-day problems.Knowledge about quantitative reasoning develops a tendency within the students to apply it to solve problems and make correct choices. The study is particularly helpful while pursuing a science or social science discipline.

Example problems based on quantitative reasoning
In this section, we will discuss some of the problems based on quantitative reasoning and try to solve them using simple steps.The first thing is to clearly understand the problem and the idea behind it. Then you need to apply the steps of quantitative reasoning and figure out the solution to the problem. Finally, you can begin addressing the other questions in the same way.
The article will help explain how to address each question basis the setup mentioned in the quantitative reasoning guide.
Example 1:
$7500 is the cost of prime farmland per acre. The land of the building costs $1.1 million per hectare. The below table shows the cost of buying land in thousands of dollars per hectare. The amount is paid along with the cost of buying the land.
1 hectare= 10000 m2 = 2.47 acres
How many hectares of farmland can be purchased for one hectare of dilapidated sewage work and washing for housing use?
Solution:
Step1: Compute the total cost of building on land and the costs related to sewage work for housing use.
1100000+358000=1458000
Step2: Divide the total cost by the cost of the farmland
1458000÷7500=194.4
Step3: Divide the cost by how many acres are equivalent to 1 hectare (2.47)
194.4÷2.47=78.7 hectares
Hence, the answer is 78 hectares.
Example 2:
A football ground is 70m wide and 144m in length. Estimate the area of thefootball ground in hectares.
1 hectare= 10000 m2 = 2.47 acres
Solution:
Step1: To determine the correct answer, you need to look at the units of measurement
Step2: 70mx144m= 10080m2
Step3: You are aware that m2 can bechanged into hectares
Step4: 10080m2÷10000m2= 1.008 hectares
Hence, the answer is 1.008 hectares.
Example 3:
The graph below shows Sam’s marks in four assignmentsas a freshman at college.
In the next year of college, Sam scored79marks in A5. Calculate the change in his marks in the next year compared to the average assignment marksas a freshman.
Solution:
Step1: Take out the average assignment score as a freshman by adding all the numbers and dividing it by the total numbers present there. As a freshman, there were four assignments, so divide by 4.
86+92+88+90= 356
356÷4= 89
Step2: In the next year, Sam has attained79marks in A5. Here you need to determine the difference between the average marksas a freshman with the A5 points.
89 (first year average)-79 (A5 points) = 10.
Hence, the answer is 10.
