Answer 1

Answer:

10%

Step-by-step explanation:

Initial no. of students = 1000

Final no. of students = 1100

Therefore, % increase =

$\frac{final - initial}{initial} \times 100 \\ = \frac{1100 - 1000}{1000} \times 100 \\ = \frac{100}{1000} \times 100 \\ = 10\%$

Answer 2

Answer:

10%

Step-by-step explanation:

Initial no. of students = 1000

Final no. of students = 1100

Therefore 100% increase=

Therefore, % increase =

$\sf{ \frac{final - initial}{initial} = \times 100}$

$\sf \frac{1100 - 1000}{1000} \times 100$

$\sf \frac{100}{1000} \times 100$

$\sf = 10\%$
