A does 1/10 per day on his own, so in 6 days he's done 60%, leaving 40% done by B in 6 days. B will take 6 x 100/40 days on his own, ie 15 days

225 days
A and B can do a one work in 6 days If A alone can finish in 9 days B will do it in how many days?
A & B together do 1/6 in 1 day. A alone does 1/9 in 1 day so in 1 day B does (1/6 - 1/9) ie 1/18 so would take 18 days on his own.
A and B can do a work in 6 days. B alone can do in 16 days. After 3 days B withdraws. Then how many days can be needed by A to do the work alone?
-- B can do the job alone in 16 days.-- So B does 1/16 of the job per day.-- In 6 days, B does 6/16 = 3/8 of the job.-- If A and B working together do the job in 6 days, then A does the other 5/8 of the job in 6 days.-- So A does 5/48 of the job each day.-- If they begin together, then after 3 days, A has done 5/16 and B has done 3/16.Together, they've finished 8/16 = 1/2 of the job. Not so surprising, when we recallthat it takes them 6 days to do the whole thing together.-- Half of the job then remains for A to finish on his own. Since he does 5/48 per day,he needs 24/5 = 4.8 days to finish off the last half.4.8 more days
If 10 men can finish a work within 5 days how many men will finish within 20 days?
job is 50 man days, so 2½ men in 20 days but you can't get half a man, (unless he only works for 20 half-days), so 3 men for 10 days and 2 men for the other 10.

Working together A and B finish work in 16 days.If A does twice the work B does how many days does A take to finish the work alone?
The whole job takes 16 days.If you carve up the job into 48 pieces, then (48/16) = 3 pieces were done each day,of which 'A' did 2 pieces and 'B' did 1 piece.Since 'A' does 2 pieces of work a day, and a whole job consists of 48 pieces,it takes him (48/2) = 24 days to do the whole job alone.
A and B can do a one work in 6 days If A alone can finish in 9 days B will do it in how many days?
A & B together do 1/6 in 1 day. A alone does 1/9 in 1 day so in 1 day B does (1/6 - 1/9) ie 1/18 so would take 18 days on his own.
A certain number of men can finish a piece of work in 10 days If however there were 10 men less it will take 10 days more for the work to be finished How many men were there originally?
If a "certain number of men" less 10 takes 20 days (twice as long) to finish the piece of work, then the "certain number of men" who can finish the work in 10 days would 20. If it takes 10 men less twice as long to do the work, then twice 10 men (20) can finish the job in 10 days.
20 men take 15 days to finish a job how many days can 25 men finish that work?
Use ratios, 20/15 = 25/x Multiply 15 by 20, then divide by 25. So 25 men could finish a job in 12 days.
