15%

- Let's say the original salary is $100.

- First, a 15% increase: $100 * 0.15 = $15, so the new salary is $115.

- Then, a 10% reduction: $115 * 0.10 = $11.50, so the new salary is $115 - $11.50 = $103.50.

- The change from the original salary is $103.50 - $100 = $3.50.

- Therefore, the percentage change is ($3.50 / $100) * 100% = 3.5% increase.

- Option 1: 10%

This is incorrect since the overall change wasn't 10%.

- Option 2: 103.5%

This is incorrect; it represents a cumulative change larger than originally possible.

- Option 3: 3.5%

This is correct; it matches our calculated percentage change.

- Option 4: 15%

This might represent just the initial increase, not the final change.

Option 3: 3.5% is correct.
