Proven Strategies for Solving GMAT Math Problems

There are a number of proven strategies that you can use to solve GMAT Math problems, including:

• Use the process of elimination. This is a great way to narrow down the possible answers and find the correct answer more quickly.
• Work backwards. This can be helpful for solving problems that are difficult to solve using traditional methods.
• Use estimation. This can be a helpful way to get a general idea of the answer before you do the exact calculations.
• Use your calculator wisely. The GMAT Math section is calculator-based, so you should use your calculator to your advantage.

Practice Questions with Detailed Explanations

The best way to prepare for the GMAT Math section is to practice, practice, practice. Here are a few practice questions with detailed explanations to help you get started:

Question 1:

If x + y = 10 and xy = 24, what is the value of x² + y²?

Answer: 130

Explanation:

We can use the formula for the square of a sum: (a + b)² = a² + 2ab + b².

Substituting x + y for a and xy for b, we get:

(x + y)² = x² + 2xy + y²

We know that x + y = 10 and xy = 24, so we can substitute these values into the equation:

(10)² = x² + 2(24) + y²

Simplifying the equation, we get:

100 = x² + 48 + y²

Solving for x² + y², we get:

x² + y² = 100 - 48

x² + y² = 130

Question 2:

A train leaves Chicago at 10:00 AM and travels at a speed of 70 mph. Another train leaves St. Louis at 11:00 AM and travels at a speed of 80 mph. If the distance between Chicago and St. Louis is 300 miles, at what time will the two trains meet?

Answer: 1:30 PM

Explanation:

To solve this problem, we need to find the time it takes for each train to travel 300 miles.

The first train travels at a speed of 70 mph, so it will take x hours to travel 300 miles:

70x = 300

x = 4.29 hours

The second train travels at a speed of 80 mph, so it will take y hours to travel 300 miles:

80y = 300

y = 3.75 hours

The two trains will meet x + y hours after the first train leaves Chicago:

x + y = 4.29 + 3.75

x + y = 8.04 hours

Since the first train leaves Chicago at 10:00 AM, the two trains will meet at:

10:00 AM + 8.04 hours

1:30 PM

Expert Advice from GMAT Experts

In addition to the strategies and practice questions above, here are a few expert advice from GMAT experts:

• Start preparing early. The GMAT Math section is challenging, so it's important to start preparing early. This will give you plenty of time to learn the material and practice your skills.
