Which of the following statements about the rate of employment figures provided in the table is TRUE?

Correct option is A

Given:

Table showing the rate of employment (in percentage) at various levels across years.

Formula Used:

Percentage Increase = $$\frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100$$​

Solution:

Option A: Rate of employment at secondary level increased by 50% between 1995 and 2000.

1995 Secondary level = 12%

2000 Secondary level = 18%

Percentage increase = $$\frac{18 - 12}{12} \times 100 = 50\%$$​​

This statement is TRUE.

Option B: Rate of employment at secondary level increased by 10% between 2000 and 2005.

2000 Secondary level = 18%

2005 Secondary level = 20%

Percentage increase $$= \frac{20 - 18}{18} \times 100 = 11.11\%$$​​

This statement is FALSE.

Option C: Rate of employment at higher level increased by 25% between 1995 and 2000.

1995 Higher level = 15%

2000 Higher level = 20%

Percentage increase = $$\frac{20 - 15}{15} \times 100 = 33.33\%$$​​

This statement is FALSE.

Option D: Rate of employment at secondary level increased by 20% between 2005 and 2010.

2005 Secondary level = 20%

2010 Secondary level = 25%

Percentage increase = $$\frac{25 - 20}{20} \times 100 = 25\%$$​​

This statement is FALSE.

The correct statement is Option A: Rate of employment at secondary level increased by 50% between 1995 and 2000.
