Question

Answer 1

Answer:

i think this is the answer

Step-by-step explanation:

ratio of boys : girls = 200 : 100

                               = 2:1

ratio of girls and teachers = 2: 1     ( same as boys : girls)

             girls/teachers = 2/1

    we know that no. of girls are 100

   100/teachers = 2/1

number of teachers is 100/2 = 50

therefore , number of teachers is 50
