Practice Questions and Solutions

Question 1:

A company sells three types of laptops: Model A, Model B, and Model C. The following data is known about the sales:

• The total number of laptops sold is 1,000.
• The ratio of Model A to Model B sales is 3:2.
• The number of Model C laptops sold is 200 less than the number of Model B laptops sold.

How many Model B laptops were sold?

Solution:

Let's assume the number of Model B laptops sold is x.

According to the ratio of sales, the number of Model A laptops sold is (3/2)x.

According to the information about Model C, the number of Model C laptops sold is x - 200.

Since the total number of laptops sold is 1,000, we have the equation:

x + (3/2)x + (x - 200) = 1,000

Solving the equation, we get:

x = 300

Therefore, the number of Model B laptops sold is 300.
