Answer:
50men working in 5days will lay 100 meters
Step-by-step explanation:
If 20men working for 10days lays 500meters
then, 1 man will lay 10,000 meters in 10 days
also, 1 man will lay 1000 meters in 1 day
If 1 man lays 1000 meters in 1 day,
Then, 50 men will lay (1000 meters / 50 ); 20 meters in 1 day
also, the same 50 men will lay (20 meters x 5days); 100 meters in 5 days.
Therefore, 50men working in 5days will lay 100 meters
