Answer 2

nos of students present=64%

nos of students absent=187

let x be the total number of students

$x - 64\% \times x = 187 \\ x - \frac{64}{100} \times x = 187 \\ \frac{100x - 64x}{100} = 100 \times 187 \\ 100 \times \frac{36x}{100} = 18700 \\ 36x = 18700 \\ x = \frac{18700}{36} = \frac{4675}{36} \\ = 519.44 \\ therefore \: the \: total \: nos \: of \: students = 519.44$
