The laptops sold by D included 33.33% defective laptops. What is the number of non-defective laptops sold by D?

Read the following pie chart carefully and answer the questions given below. The following pie chart shows the percentage distribution of laptops sold by four persons A, B, C and D.

The correct option is none of these.

Step 1: Extract data from the pie chart

From the provided pie chart, we can explicitly observe the following key data points:
• Total number of laptops sold = 150
• Percentage of laptops sold by person D = 38%

Step 2: Calculate the total laptops sold by D

$\text{Total laptops sold by D}=38\%\text{of}150$

$=\frac{38}{100}\times 150=57$

Step 3: Calculate the number of non-defective laptops sold by D

The question states that 33.33% of the laptops sold by D are defective. In terms of simple fractions, 33.33% is equivalent to $\frac{1}{3}$.

Therefore, the fraction of non-defective laptops sold by D is:

$1-\frac{1}{3}=\frac{2}{3}$

Now, calculate the exact number of non-defective laptops sold by D:

$\text{Number of non-defective laptops}=\frac{2}{3}\times 57=38$

Conclusion:

The total number of non-defective laptops sold by D is 38. Since 38 is not among the given numerical choices (19, 26, 22, 25), the correct option is none of these.
