1 Answer
C)
let the number of director be X and office boy be 120-x
total salary of director and office boy = 120*3750 =
Rs.450000
total salary of director = 6000x
total salary of office boy = 3000* (120 -x)
total salary of director + total salary of office boy=450000
450000 = 6000x + 3000 * (120 -x)
3000x =90000
x = 30 number of director
number of office boy = 120-30 = 90
ratio of director to office boy = 30:90 = 1:3
let the number of director be X and office boy be 120-x
total salary of director and office boy = 120*3750 =
Rs.450000
total salary of director = 6000x
total salary of office boy = 3000* (120 -x)
total salary of director + total salary of office boy=450000
450000 = 6000x + 3000 * (120 -x)
3000x =90000
x = 30 number of director
number of office boy = 120-30 = 90
ratio of director to office boy = 30:90 = 1:3
