Question : 39 of 100

Marks: +1, -0

Jail with highest placement rate of trained convicts is:

Validate

Solution:

Concept:

Placement rate is the percentage of convicts placed out of those trained.

Explanation:

For each jail, compute placement rate as

(\text{placed} / \text{trained}) \times 100

Use the given table: row headers are jails; column Y = trained convicts, column Z = placed.

Jail A:

\frac{25}{45} \times 100 = 55.55\%

Jail B:

\frac{461}{903} \times 100 = 51.05\%

Jail C:

\frac{474}{940} \times 100 = 50.42\%

Jail D:

\frac{416}{869} \times 100 = 47.87\%

Jail E:

\frac{254}{544} \times 100 = 46.7\%

Jail F:

\frac{174}{464} \times 100 = 37.5\%

The highest value is 55.55% for jail A.
