A planetary rover analyzes a soil sample containing the element boron, which naturally consists of only two stable isotopes: $^{10}\text{B}$ with an atomic mass of $10.01\text{ amu}$ and $^{11}\text{B}$ with an atomic mass of $11.01\text{ amu}$. If high-precision spectrometry determines that the average atomic mass of boron in the sample is $10.81\text{ amu}$, what is the percent abundance of the $^{11}\text{B}$ isotope in this sample?
