I know a 5 digit number having a property that With a 1 after it, it is three times as large as it would be with a one before it.
Guess the number ?
42857
Let the number be x
10x +1 = 3(100,000 + x)
=> x = 42857.

I want to fill my bucket using both cold and hot water.
I have two taps for both cold and hot water. The hot water tap fills the bucket in exact 6 hours and cold water tap fills the bucket in exact 4 hours.
I turn both of them simultaneously but I forgot to turn off another tap which removes the water out of the bucket. This tap can empty the bucket in 12 hours.
How Long will it take to fill the bucket?
3 hours
Explanation :
(1/6 + 1/4 - 1/12) ^ (-1)
= (1/3)^(-1) = 3
I have a five and a three-gallon jar. Assuming there is an infinite supply of water, how can I measure one-gallon water?
-> Fill up the 3 gallon jar first , Pour it into the five gallon jar.
-> Fill up the 3 gallon jar again, and fill up the rest of the 5 gallon jar,
=> and you should have 1 gallon left over in the 3 gallon jar.
