What percent of group of \(10\) turtles no have spots?

1) \(5\) turtles no have spots.
2) \(50\) percent turtles in group have spots.

Correct answer is D

To solve, we want percent of turtles without spots in group of \(10\).

Statement 1: \(5\) turtles no have spots. Since total turtles in group is \(10\), we can say \(5\) out of \(10\), or \(50\%\), no have spots. Sufficient.

Statement 2: \(50\%\) turtles in group have spots. This means other \(50\%\) no have spots. Sufficient.

Combine both: Each statement sufficient. Correct answer is D
