Question

Twelve men can do a piece of work in 10 days. a????er they have started for 6 days, 4 more men join them. how many days will the men take to complete the remaining work?

Answer 1

If 10 men can build a wall in 120 days what is the size of wall that 25 men can built in 15 days

Answer 2

Step-by-step explanation:

Assume 1 man does 1 unit of work in 1 day.

Then total work = 12×18=216 units

In initial 6 days, 12 men worked.

Work completed = 12×6=72 units

Remaining work = 216 - 72 = 144 units

Then 16 men work

Time required for them to finish the job =14416=9=14416=9 days
