Q:

A number of cats got together and decided to kill between them 999919 rats. Every cat killed an equal number of rats. Each cat killed more rats than there were cats. How many rats do you think that each cat killed ?

 A) 1009 B) 991 C) 2000 D) 1000

Q:

Which number multiplied by itself will give the output as 12345678987654321 ?

11 * 11 = 121

111 * 111 = 12321

what we observe is that the square of the number follows a pattern: 2 1's gives 121. 3 1's gives 12321.

so to get 12345678987654321 we need to get square of 9 1's(111,111,111).
