An arbitrary number could be expressed as

A1A2 A3 ....An-1An

Each digit in the number is unknown and the number is also unknown.
Applying a right shift to the number, the new number becomes

An A1 A2 A3 .... An-1

(a) It was found that the new number is 1.5 times larger than the original number.
What will be the original number?

(b) If the original number is 1.5 times larger than the new number.
What will be the original number?
