Question: At a certain restaurant, a meal consists of one appetizer, one main course, and one dessert. If the restaurant has 2 appetizers, 3 main courses, and 5 desserts, then how many different meals could the restaurant serve?

1. 60
2. 30
3. 10
4. 6
5. 3

Correct Answer: B
Solution and Explanation:
Approach Solution 1:

This is a GMAT problem-solving question in which you have to use the details given in the question to solve the problem. The problems in this category are coming from different areas of math topics. This one particularly is from permutation and combination.

The option is given in such a way that it is difficult to guess the correct answer. The candidates need to know the right approach to get the required answer. Only one of the given 5 choices is correct.

If a restaurant serves three types of main courses, five desserts, and two kinds of appetizers, then it has a limited menu. There is a rule that there will be an appetizer, a main course, and a dessert at every meal.

The candidates should know the basics of permutation and combination to solve this problem.
We can select 1 main course from the set of three main courses in 3c1 = 3
We can select 1 dessert from a set of five desserts in 5C1 ways = 5
We can select 1 appetizer from a set of 2 desserts in 2C1 = 2
The total number of ways in which the meal can be formed can be calculated by using the fundamental principle of counting.
Taking the product of all the ways we get, 3 * 5 * 32 = 30

Hence there are 30 ways to form a meal from the given amount of items.

Approach Solution 2:

This is a GMAT problem-solving question in which you have to use the details given in the question to solve the problem. The problems in this category are coming from different areas of math topics. This one particularly is from permutation and combination.

The option is given in such a way that it is difficult to guess the correct answer. The candidates need to know the right approach to get the required answer. Only one of the given 5 choices is correct.

If a restaurant serves three types of main courses, five desserts, and two kinds of appetizers, then it has a limited menu. There is a rule that there will be an appetizer, a main course, and a dessert at every meal.

You can choose 2 appetizers in 2 ways,
Three main courses can be chosen in three different ways.
You can choose among five desserts in the 5 ways
We are asked to find out the number of ways to make the meal. We can take any one of the appetizers among the two, any one of the desserts among 5, and any one of the main courses among the 3.
The total ways will be the product of the choices = 5 * 3 * 2 = 30

The correct choice is 30.

Approach Solution 3:

This is a GMAT problem-solving question in which you have to use the details given in the question to solve the problem. The problems in this category are coming from different areas of math topics. This one particularly is from permutation and combination.

D.6. The number of different meals is equal to the number of ways to choose one item from each category, which is 2 * 3 * 5 = 30. However, each meal can also be ordered in a different order (appetizer, main course, dessert), so we need to divide the total by 3 to get the number of different meals, which is 30 / 3 = 6.

“At a certain restaurant, a meal consists of one appetizer, one main co" - is a topic of the GMAT Quantitative reasoning section of GMAT. This question has been borrowed from the book “GMAT Official Guide Quantitative Review”.

To understand GMAT Problem Solving questions, applicants must possess fundamental qualitative skills. Quant tests a candidate's aptitude in reasoning and mathematics. The GMAT Quantitative test's problem-solving phase consists of a question and a list of possible responses. By using mathematics to answer the question, the candidate must select the appropriate response. The problem-solving section of the GMAT Quant topic is made up of very complicated math problems that must be solved by using the right math facts.
