Answers
Answer:
45 men can finish a job in =16 days
after 6 days the situation is
45 men can finish a job in =16–6=10 days
1 man can finish this job in =10×45=450 days
since 30 more men join in so now
45 +30=75 men can finish the job in =450/75=6 days.

45 men 1 day work is … 1/16
45 men work for 6 days ..… 1/16=3/8 work done
1-3/8 = 5/8 … work left
After 6 days 30 men join …..total men=75 men
if 45 men 1 day work is 1/16… then 75 men 1 day work will be 5/48 (perform cross multiplication)
X=days to complete remaining work 5/48 * x=5/8
X= 6 days

When the new men are added the old are still working. A vital point that people ignore generally that changes the equation.

Let the number of men be m, work be w, and days be d.
m : w : d
45 : 1 : 16
Logic: less days = less work
m : w : d
45 : 1 : 16
45 : 1/16 : 1
The rate of 45 men is (1/16) works per day.
After 6 days:
Works completed: (1/16) x 6 = 3/8
Works left: 1 - (3/8) = 5/8
30 more men join them:
Men: 45 + 30 = 75
1 Man's rate = (1/16)/45 = 1/720
75 Men's rate = (1/720) x 75 = 15/144
Time to complete remaining work:
(5/8)/(15/144)
= 6 days

The work requires 45x16 = 720 worker-days.
In the first 6 days the work completed is the equivalent of 45x6 = 270 worker-days.
What remains to be done after the first 6 days = 720=270 = 450 worker-days..
Now the 450 worker-days of work can be completed by (45+30 = 75) 75 workers in 450 worker-days/75 workers = 6 days.

Men = 45
Days = 16
Total Work = 720 Units
6 days work = 45 * 6 = 270 units
Remaining = 720 - 270 = 450 units
Men = 30 + 45 = 75 men
work = 450
Time = 450/75 = 6 days
Total Time taken will be 12 days
