Question

Out of a class of 45 students , five were absent and 30% of the students failed to do their homework. Find how many student able to do their homework

Answer 1

Answer:

HOPE IT HELPS!!!!!

Step-by-step explanation:

Number of students absent = 5

Number of students who failed to do the homework = 30% of 40

                                                                                       = 30/100 * 40

                                                                                       = 12

Number of students who did their homework = 45 - (12 + 5)

                                                                            = 45 - 17 = 28

Answer 2

Answer:

• 28 Students able to do their Homework.

Given :

• Total number of students = 45

• Number of students absent = 5

• Number of students present = 40

To find :

• Number of Students able to do their Homework =?

Step-by-step explanation:

Total number of students = 45 [Given]

Number of students absent = 5 [Given]

Number of students present = 40 [Given]

Number of students who failed to do the homework = 30% of 40

=30/100×40

= 3 × 4

=12

Now,

Number of students who did the homework = Number of students present - Number of students who failed to do the homework.

Substituting the values, we get,

= 40 - 12

= 28

•°• 28 Students able to do their Homework.
