The question does not state what happens on the 6th day, but let's assume that on that day he gives his last rupee to a beggar. We can then work backwards: 5th day: 1 rupee for food + 1 rupee for beggar = 3 rupees at the start of that day; 4th day: spend 3 + 1 = 7 rupees at start; 3rd day: 7 + 1 = 15 rupees; 2nd day: 15 + 1 = 31 rupees; 1st day: 31 + 1 = 63 rupees at the start of the 1st day.
