Question

Arun had some money. he gave one rupee to beggar and half of the remaining money was spent for buy food. Same thing happened second day he gave one rupee to beggar from remaining money of first day. this continued on the six day he had 0 rupee, then how much money he had on first day?

Answer 1

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.
