Question

Is 697345 divisible by 11?

Answer 1

Answer:

Then, we know only 0 and multiples of 11 as 11, 22, 33 and so on will be divisible by 11. Now, we can clearly see only the number 888888 gives the number as 0 which is divisible by 11 and all other numbers are not divisible by 11. Therefore the total number of numbers which are not divisible by 11 are 6.

Answer 2

A compass has a magnetic needle attached to it which can rotate freely. The magnet always points to north - south direction which is marked on compass and thus helps in finding direction.
