Describe why both Roxana and Yezad are puzzled about the amount of money in the budget envelopes.

Roxana is puzzled because she counts out a total of 180 more rupees than she thinks should be in the envelopes. There is money in the electricity envelope even after the bill has been paid, there is bread and butter money even though they have been out of butter for several days. She cannot account for how the extra money came to be in her budget envelopes. Yezad is puzzled because he knew that he only added 120 rupees to the budget envelopes and he cannot figure out where the extra 60 rupees came from.
