Answer 1

From the presented detailed facts, this riddle cannot be properly answered if you are trying to find the extra one (1) rupee in the "Balance" column because the sum in the "Balance" column varies each time you spent different amounts of rupees. For Example:
 SPENT BALANCE
   5/-         45/-
   5/-         40/-
   5/-         35/-
   5/-         30/-
   5/-         25/-
   5/-         20/-
   5/-         15/-
   5/-         10/-
   5/-          5/-
   5/-          0/-
  50/-        225/-
By looking at this table, the first "Spent" column also have the same total of 50 rupees as the question table, by adding all the spent amount not unlike this"Balance" column showing 225 rupees, if you try to add all the "Balance" amount. Therefore, it clearly shows that adding the second "Balance" column is meaningless.
