During Holy week, 25% of the office workers went out of town, 3/5 stayed at home while the rest numbering nine had to work overtime. How many total office workers are there?

let 'x' be the total number of office workers
25% of the office workers went out of town: 0.25x
3/5 stayed at home: (3/5)x
the workers that worked overtime: 9
now we can write
0.25x + (3/5)x + 9 = x
by solving we find
x = 60 workers
