A number of cats got together and decided to kill between them 999919 mice. Every cat killed an equal number of mice.
How many cats do you think there were?
Ob, by the way let me clarify just two points—it is not one cat killed the lot, because I have said ‘Cats’ and it is not999919 cats each killed one mouse, because I have used the word ‘mice’.
I can give you just one clue—each cat killed more mice than there were cats.View SolutionSubmit Solution 7974 views

Recently, while in London, I decided to walk down the escalator of a tube station. I did some quick calculations in my mind. I found that if I walk down twentysix steps, I require thirty seconds to reach the bottom. However, if I am able to step down thirtyfour stairs I would only require eighteen seconds to get to the bottom.
If the time is measured from the moment the top step begins to descend to the time I step off the last step at the bottom, can you tell the height of the stairway in steps?View SolutionSubmit Solution 4737 views

Two women were selling marbles in the market place —one at three for a paise and other at two for a paise. One day both of them were obliged to return home when each had thirty marbles unsold. They put together the two lots of marbles and handing them over to a friend asked her to sell them at five for 2 paise. According to their calculation, after all, 3 for one paise and 2 for one paise was exactly the same as 5 for 2 paise.
But when the takings were handed over to them, they were both most surprised, because the entire lot together had fetched only 24 paisel If however, they had sold their marbles separately they would have fetched 25 paise.
Now where did the one paise go? Can you explain the mystery?View SolutionSubmit Solution 3113 views

The bewildered Shuba thought for a few moments and finally she handed over the exact fulfilment of the order to the man—with a smile.
How would you have handled the situation?View SolutionSubmit Solution 2289 views
