Question :

the number of students in 2000 was 900 . if became 1100 in 2001.the percentage increase is ?

Answer :

$\sf\pink{Given:}$

• number of students in 2000 was 900 .

• number of students in 2001 is 1100 .

$\sf\pink{To\:find:}$

• increase percentage ?

Explanation :

To find the increase percentage we need to find the number of students increased .

Number of students increased = Number of students in 2001 - No. of students in 2000 .

$\\ \longrightarrow\sf{ 1100 - 900}$

$\\ \longrightarrow\sf{ 200}$

Therefore 200 students were increased in 2001 .

$\sf{Percentage = \dfrac{Increased\: number}{number\:of\: students\:in\:2000}\times 100}$

$\\ \longrightarrow\sf{\dfrac{200}{900}\times 100}$

$\\ \longrightarrow\sf{\dfrac{200}{9}}$

$\\ \longrightarrow\sf{22.22}$

Percentage is 22.22 %
