Answer 2

Heya...
Here is your answer ----

Let the total number of employees in the school be x.

=> Percentage of teachers = 30%

ATQ
__________

=> 30% of x = 120

=> 30/100 × x = 120

=> 3/10 x = 120

=> 3x = 120 × 10

=> 3x = 1200

=> x = 1200 ÷ 3

=> x = 400

The total number of employees in the school is x = 400.
