If you started a business in which you earned Rs.1 on the
first day, Rs.3 on the second day, Rs.5 on the third day,
Rs.7 on the fourth day, & so on.
How much would you have earned with this business after 50
years (assuming there are exactly 365 days in every year)?

Answer Posted / vinod gupta
Let n be the no. of days
Then (n*2)-1 gives us the amount that you earn for that many
days.
Since we need to find for 50 years and each year has 365 days
Thus, n = (365*50) = 18250
Therefore on 50 years you get,
(18250*2)-1 = 36500-1 = 36499
This is the amount you earn on 50 years.
But we need to find the total amount that we would earn
after 50 years.
For this we need to add the amount from day 1 till 50 years
i.e; 18250
Thus we have,
1 + 3 + 5 + 7 + 9 + ... + 36499 = 333062500
Thus after 50 years we have Rs.333,062,500
