Question

Q1. Il 55% of student in class go for a picnic
what percent of student do not go for
picnic​

Answer 1

Answer:

Let the number of students in the class be x

Percent of students who went for the picnic = 55%

Therefore, number of students who went for the picnic = (55/100*x) students

= (11x/20) students

Therefore, number of students who didn't go for the picnic = {x-(11x/20)} students

= {(20x - 11x) /20} students

= {9x/20} students

Therefore, percent of students who didn't go for the picnic = {(9x/20)/x *100}%

= {9x/20*1/x*100}%

= {9/20*100}%

= {9*5}%

= 45%
