The interest on Rs. 1000 @7% for a certain number of days starting from Jan 1, 2001 is Rs. 14. How many days?


73 days.


74 days.


72 days.


75 days.

Ans: a

We have r = 7%, P = 1000, I = 14, so t = ${100 × 14}/{1000 × 7}$. We get t = 1/5. The given year is not a leap year. So it has 365 days. Since 365/5 = 73, the number of days is 73.
