Answer 2

Answer:

144 men

Step-by-step explanation:

let work done by one man be 'a'

then work done by 120 men = 120a

120a takes 180 days

total work = 120a x 180 = 21600a

let the no of men who complete the task in 150 days be 'x'

150ax = total work

so 21600a = 150ax

150x = 21600

15x = 2160

x = 2160/15 = 144 men
