How many years will
200 amount to 280 at 8.66% per annum if the interest to be applied is simple interest.
We know simple interest formula:
A = P(1 + rt)
A = 280
P = 200
r = 8.66% = 0.0866
280 = 200(1 + 0.0866t)
1 + 0.0866t = 1.4
0.0866t = 0.4
t = 4.61 years (about 4 years 7 months)
Thus, 4.61 years or about 4 years 7 months will take 200 amounting to 280 at 8.66% per annum.
