pls answer the question​

Answer 1

Answer:

756 pupils cannot swim.

Step-by-step explanation:

Enrolment of the school is 1050

28% of them can swim

Therefore, (100 - 28)% = 72% of them cannot swim

$=\frac{72}{100} .1050 =(36).(21)= 756$ pupils cannot swim.

Answer 2

Answer:

756 pupils cannot swim in the school

Step-by-step explanation:

percentage of pupils which can't swim = (100-28)%

                                                                 = 72%

Number of pupils who can't swim = $\frac{72}{100}$ × 1050

                                                        = $\frac{72}{10}$ × 105

                                                        = $\frac{36}{5}$×105

                                                        = 36 × 21

                                                        = 756

∴ 756 pupils cannot swim in the school
