16 girls, so 14 boys ... (30 - 16)
6 boys wear spectacles ... (14 - 8)
4 girls wear spectacles ... (10 - 6)
6 boys wear spectacles ... (14 - 8)
4 girls wear spectacles ... (10 - 6)
Total students = 30
Students who wear spectacles = 10
Girls = 16
Boys who do not wear spectacles = 8
Number of girls who wear spectacles = Total students who wear spectacles - Boys who do not wear spectacles
Number of girls who wear spectacles = 10 - 8
Number of girls who wear spectacles = 2
Therefore, there are 2 girls who wear spectacles.
Step 1: Total number of students in the class is 30.
Step 2: Out of these 30 students, we know that 10 students wear spectacles.
Step 3: We also know that there are 16 girls in the class.
Step 4: From the given information, we are given that there are 8 boys who do not wear spectacles.
Now, let's calculate the number of girls who wear spectacles:
Total number of students wearing spectacles = 10 students.
Out of these 10 students, some are girls and some are boys.
Number of boys wearing spectacles = Total number of students wearing spectacles - Number of girls wearing spectacles.
Number of boys wearing spectacles = 10 - x, where x represents the number of girls wearing spectacles.
We are given that there are 8 boys who do not wear spectacles, so the number of boys wearing spectacles must be:
Number of boys wearing spectacles = Total number of boys - Number of boys who do not wear spectacles.
Number of boys wearing spectacles = Total number of boys - 8.
Total number of boys = Total number of students - Total number of girls.
Total number of boys = 30 - 16 = 14.
Now we can substitute the values to find x (number of girls wearing spectacles):
10 - x = 14 - 8
10 - x = 6
-x = 6 - 10
-x = -4
x = 4
Therefore, there are 4 girls who wear spectacles in the class.
