Attach shows the scores of students in an exam


\begin{gathered} \text{(students scored above 86\%) = }\frac{\text{ number of students score above 86\%}}{\text{Total scored }}\text{ x }(100)/(1) \\ \text{(students scored above 86\%) = }\frac{\text{8+5.9+2.2+2}}{1.4+2.2+4.5+6.2+8.5+16.5+18+16.3+8+8+5.9+2.2+2}X(100)/(1) \\ \\ \text{(students scored above 86\%) = }(18.1)/(99.7)\text{ X }(100)/(1) \\ \text{(students scored above 86\%) = }18.15\text{ \%} \\ \text{(students scored above 86\%) = 18\%} \end{gathered}

Hence the correct answer = 18% Option A
