Answer 2

➤ Answer :-

Number of students can swim $=$

$\dashrightarrow \sf60 \bf\% \sf \: of \: 30$

$\dashrightarrow \sf \frac{60}{100} \times 30$

$\dashrightarrow \sf \frac{60 \times 30}{100} = \frac{1800}{100}$

$\dashrightarrow \sf \cancel \frac{1800}{100} = 18$

Number of students cannot swim $=$

$\dashrightarrow \sf30 - 18$

$\dashrightarrow \sf12$

$\Huge\therefore$12 students in class cannot swim.
