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)?

The Answer is 36499

Solu:
365 X 50 = 18250 Days.
18250 X 2 = 36500
For ODD number 36500 - 1 = 36499

The Answer is 333062500

Solu:
365 X 50 = 18250 Days.

18250 X 2 = 36500
For ODD number 36500 - 1 = 36499 (This is 50th year last day Earning)

18250 Consider this as N
After 50th year the Earnings would be N square (i.e = 333062500)

1st day = 1
2nd day = 4
3rd day = 9
4th day = 16
5th day = 25
