Ballparking: Solving Problems Quickly and Intelligently

The video introduces the concept of ballparking, a method of making quick, intelligent guesses instead of seeking perfect results. It is likened to baseball, where keeping the ball inside the ballpark is more important than hitting it perfectly. The technique is useful in conversations and essential for passing certain tests. The video demonstrates ballparking through two examples: estimating the most popular food in the world and solving a complex math problem similar to those found on the GMAT exam. The process involves using known information, making educated guesses, and eliminating unlikely options.

What is the main idea behind the ballparking technique?

• To always use exact calculations

• To avoid making any guesses

• To make quick and intelligent guesses

• To achieve perfect results every time

Which two countries' cuisines are estimated to be the most popular using ballparking?

• Italian and Japanese

• American and Fast Food

• Chinese and Indian

• Mexican and Thai

What is the first step in solving the math problem using ballparking?

• Use a calculator to find the square root of 24

• Ignore the square root of 24

• Estimate the square root of 24 as 5

• Calculate the exact square root of 24

How do you handle the fraction in the math problem using ballparking?

• Ignore the fraction completely

• Estimate the denominator as more than 5

• Assume the denominator is less than 5

• Calculate the exact value of the denominator

Which option is eliminated because it is too high in the math problem?

• Option D

• Option C

• Option B

• Option A
