Question

out of a class of 35 students 5 were absentresult 30% of the remaining had failed to do homework find the number of students who did the homework

Answer 1

Given,
Total number of students = 35
No.of students absent = 5
So, no.of student now = 35-5 = 30
We have, No. of students failed to do homework = 30% of 30=9
Now,
No.of students did the homework=30-9= 21
Hence, 21 students did the homework.
