Flauer [41]

The ratio of the number of female attendants to the number of male attendants is 21/17

let

number of female attendant = x
number of male attendant = y

900 = 1200x + 800y / (x + y)

900x + 900y = 1200x + 800y

900x + 1200x = 800y + 900y

2100x = 1700y

x : y = 2100 / 1700

x : y = 21 ; 17
