The number of students who do not bring lunch will be 210.
The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
Lunch A survey showed that 30% of students bring their lunch to school. The survey polled 300 students. Then the percentage of students who do not bring lunch will be
⇒ 100% - 30%
⇒ 70%
Let x be the number of students who do not bring lunch. Then we have
x = 70% of 300
x = 0.70 × 300
x = 210
The number of students who do not bring lunch will be 210.
