Answer:
1428000
Explanation:
You want the principal that would result in interest of 11900 at a rate of 6% for a period of 50 days.
Ordinary interest
Ordinary interest is calculated on the basis of 360 days per year. The fraction of a year represented by 50 days is 50/360, so the interest formula tells us ...
I = Prt . . . . . . . where P is the principal at rate r for t years
11900 = P·0.06·(50/360)
P = 11900/(0.06·50/360) = 1428000
The principal amount is 1428000.
