Answer:

Answer: There are 918 pupils now.

• Rise in percentage:

[tex] \dashrightarrow \: { \tt{(100 \% + 8\%) = 108\% }}[/tex]

• let current number of pupils be n

[tex]{ \tt{n}}\dashrightarrow \: { \tt{108\% \times 850}} \\ \\ { \tt{n = \frac{108}{100} \times 850}} \\ \\ { \tt{n = 918 \: pupils}}[/tex]
