Question

the school auditorium is full of 2500 people out of these 2218 are students 217 are parents and the remaining are teachers how many teachers are there in the auditorium?​

Answer 1

$\sf\large\underline{Given:}$

$\tt{\implies Total\:_{(No\:of\: people)}=2500}$

$\tt{\implies Number\:_{(students)}=2218}$

$\tt{\implies Number\:_{(parents)}=217}$

$\sf\large\underline{To\: Find:}$

$\tt{\implies Number\:_{(teachers)}=?}$

$\sf\large\underline{Solution:}$

• To calculate the number of teachers out of 2500 people , we have to assume the number of teachers be x than setting up the equation]

$\rm{\implies Total\:sum\:_{(students+parents+teachers)}=Total\:_{(people)}}$

$\rm{\implies 2218+217+x=2500}$

$\rm{\implies 2435+x=2500}$

$\rm{\implies x=2500-2435}$

$\rm{\implies x=65}$

$\bf\large{Hence,}$

$\tt{\implies Number\:_{(teachers)}=65}$

$\tt{\underbrace{AnsweEr:-65}}$
