Puzzles contest - 104

[HELP]

1. There are 150 members in my club. We decided to have a ping pong
tournament. All the members came forward to play in the game. Every
time a member loses a game he is out of the tournament. There are no
ties. Can you tell how many games must be played in order to determine
the champion?





2. 48, 60, 58, 72, 68, 104.......Here is a sequence. Can you find the two missing terms?





3. We have an old gr~ndpa clock at home. it takes seven seconds for
this clock to strike seven gongs.Now how long do you think it will take
for striking ten Gongs





4. Can you find a number of nine non-respective digits that is
divisible by II? Find the smallest of such number as well as the
biggest.





5. It was a day of rush. I had to send off the typescript to my
publisher by the evening's mail. Mr Das Gupta, my stenographer is avery
e}~perienced person and he,I knew could do the job neatly and quickly.
But even he would take 2 hours to finish the job. This couldn't have
done! So I decided to engage another typist. She would do a neat job, I
was told, but she was not a fast typist like Mr Das Gupta. She looked
at the job and said that if she were to do the entire job by herself,
it would take her three hours I decided to let them do the job side by
side. Within how much time, can you teU, the two of themfinished the
work?

Honest is not the best policy yet if my answer to this question is right, then i owe it to kateek. i have just used his result to come up wit a better answer to 4

4. smalllest is 109002399

largest is 999240000

(all credit to karteek)

5. let total work = 6 units

then mr dass does 3 units in 1 hr

and the blondetypist does 2 units in 1 hr

so 1 hr work of both combined = 5 units

total work = 6 units

time taken = 6/5 hrs = 1.2 hrs Ans. i.e. they will finish in such a way that some letter of 1 word is typed by das and rest of letters by lol

2. i differ fromother personon this

48,58,68,78,88........

60,72,104,156

So, 2 next nos are 78,156 right?

1 & 3 are done correctly by bro
