Answer:
24 days
Step-by-step explanation:
Pond dimension = 50m × 35m
Area of the pond = 1750m²
250 men need 18 days to dig a pond of 1750 m²
250 men will do in 1 day =1750/18 m²
1 man will do in 1 day = 1750/(18×250) m²
The dimension of the pond to be dug = 70×40= 2800m²
1 man do 1750/18×250 m² in 1 day
1 man will do 2800 m² = 2800/1750/(18×250) = 7200 day
300 men will do the same work in
7200/300= 24 daya
