Question

a)140.49 b)104.94 c)104.49 d)150.00

Answer 1

If you're too lazy to figure it out from scratch, trial and error is your best friend.

Answer 2

Do you mean three years instead of 3 months?
If so then total amount paid including interest would be
2700*1.12^3 = $3793.31
So monthly payment =3793.3/36 = $105.37.
Answer b) is the closest to this calculation.
