A strange wrist watch have it hands separated equally on 9:05:25 am..and seem to be working properly.
The second hand runs at 1 rev per minute , the minute hand runs at 1 rev per hour while the hour hand runs 2 rev per day.
But everytime the hands overlaps they switch rotational speed.. Can you tell the rotational speeds of each hands when its
Does "when its 11:11:11 pm" refer to the actual time, or to the position of the hands?

On each pan of the tri-beam scale are 3 seemingly identical bells that are balanced with the other pan bells.
A) Sort out the bells-3 light bells (L=1) and 3 heavy bells (H=3) from Normal bells (N=2) by using the scale .
How many times will it take to identify their weights?
B) When you got a desired outcome on the first weighing ,how can all the bells be sorted on the 2nd weighing?
The scale works as follows:
1)Balanced : 3 weights on pans are equal ex. 6 : 6 : 6
2)One pan down : Only the heaviest ex. (5):3 :2 , (5):1:1
3)One pan up : 2 heavier weights are equal ex. (3):4 :4

One of the 12 identical coins was magnetized so that it weighs
heavier on one face and lighter on the other when placed on
a certain weighing scale. But it weighs normal like the other coins
when it is standing balanced on its side or edge.
Find out which coin is it using the weighing scale 3 times.

How many times does a 24-hour format digital clock greet or spells "hELLO" everyday?

It is 6 o'clock ..the ant from the tip of the clock's half foot Hour-hand must travel home to12 o'clock mark under the tip of 1ft Second-hand.
The clocks Minute hand is 9 inches.
The ant travels 1ft/min along the hands without stopping and reverses its direction when reaching the pivot end or the tip of the hands .
It can shift to any hand that is directly above or below it while resuming direction.
How long shall it take for the ant to arrive home?
