The average salary of workers in college is Rs 2000, the average salary of faculty being Rs 4000 and the management trainees being Rs 1250. The total number of workers could be

1) 450
2) 300
3) 110
4) 500

Read Solution (Total 1)

110

if there are x workers and y faculty members, then
2000x = 4000y +1250*(x-y)
3x=11y
y= x*3/11

so x should be multiple of 11 which is satisfied by 110 only.
