The following pie charts shows the percentage distribution of total students selected in SSC examination and percentage distribution of total boys selected students from six different zones. Study the following pie chart carefully and answer the given questions.

Total number of girls selected from zone B, zone D and zone F together is how much more or less than the total number of boys selected from zone B & zone D together?

The correct answer is 1120.

From the pie charts provided in the question:

1. Total Data Given:
- Total number of students selected = 12,000
- Total number of boys selected = 7,000

2. Calculate Total Students in Zones B, D, and F:
- Percentage of total students selected from Zone B = 12%
- Percentage of total students selected from Zone D = 20%
- Percentage of total students selected from Zone F = 10%
- Total percentage of students from Zone B, D, and F together = 12% + 20% + 10% = 42%

$\text{Total students (B + D + F)}=42\%\text{of}12000=\frac{42}{100}\times 12000=5040$

3. Calculate Total Boys in Zones B, D, and F:
- Percentage of boys selected from Zone B = 10%
- Percentage of boys selected from Zone D = 13%
- Percentage of boys selected from Zone F = 10%
- Total percentage of boys from Zone B, D, and F together = 10% + 13% + 10% = 33%

$\text{Total boys (B + D + F)}=33\%\text{of}7000=\frac{33}{100}\times 7000=2310$

4. Calculate Total Girls in Zones B, D, and F Together:
Since Total Girls = Total Students - Total Boys:

$\text{Total girls (B + D + F)}=5040-2310=2730$

5. Calculate Total Boys Selected from Zone B and Zone D Together:
- Percentage of boys from Zone B and Zone D together = 10% + 13% = 23%

$\text{Total boys (B + D)}=23\%\text{of}7000=\frac{23}{100}\times 7000=1610$

6. Calculate the Required Difference:

$\text{Difference}=\text{Total girls (B + D + F)}-\text{Total boys (B + D)}$

$\text{Difference}=2730-1610=1120$

Therefore, the total number of girls selected from zone B, zone D, and zone F together is 1120 more than the total number of boys selected from zone B & zone D together.
