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
