Answer 1

Answer:

25 men take 30 days to dig 20 holes

Step-by-step explanation:

50 men can dig 40 holes in 30 days how long will 25 men take to dig 20 holes

50 men can dig 40 holes in 30 days

=> 50 * 30 = 1500 man days required to dig  40 holes

=> 1 hole can dig in = 1500/40 = 75/2  man days

=> 20 holes can dig in = 20 * 75/2 = 750 man days

Let say 25 men take x days to dig hole = 25x  Man days

25x = 750

=> x = 30 Days

25 men take 30 days to dig 20 holes
