What were the specific monetary offerings that Balasaheb Deo was asked to make to Sai Baba upon his arrival in Shirdi?

The account in Chapter 41 details a unique financial interaction between Balasaheb Deo and Sai Baba. When Deo went for darshan, he initially offered one rupee. Baba immediately responded by saying, 'Why only one? Bring twenty.' Deo complied and gave the twenty rupees. The very next day, when Deo returned to the Mosque for darshan, Baba once again asked him for twenty rupees. The text notes that Deo gave this second amount 'with joy and satisfaction.' This repeated and specific request for money from Baba occurred during the same visit where Deo was holding a firm resolve regarding his reading of the Dnyaneshwari.
