Answer 2

correct question

$= in \: a \: class \: 55 \% \: of \: the \: student \: are \: \: boys .\\ if \: the \: number \: of \: girls \: are \: 27 \\ then \: how \: any \: student \: are \: there \: in \: the \: class \\ \\ \\ sollution \: \: \\ let \: the \: total \: number \: of \: students \: in \: \: the \: class \: be \: x \\ according \: to \: question \\ 55\% \: of \: x + 27 = x \\ \frac{55}{100} \times x + 27 = x \\ \frac{11x}{20} + 27 = x \\ 27 = x - \frac{11x}{20} \\ 27 = \frac{20x - 11x}{20} \\ 27 = \frac{9x}{20} \\ by \: cross \: multiplication \\ 9x = 540 \\ x = \frac{540}{9} \\ x = 60 \\ hence \: total \: number \: of \: student \: in \: the \: class \: = 60$
