Question

A contractor undertook to com-
plete a project in 90 days and
employed 60 men on it. After 60
days, he found that 3/4 of the
work has already been com-
pleted. How many men can he
discharge so that the project
may be completed exactly on
time?​

Answer 1

Answer:

20 men's will be discharged

Step-by-step explanation:

if 90days for 60 men

then for 60 days how many men's (x)

90/60= 60/x

x= 60×60/90

x= 3600/90

x= 40

for completing work in 60 days only 40 men required

we have 60 men

then 60-40= 20

20 men will be discharged
