I do know what this is but you are missing a big bit of info , the best way to solve is to use the grit link because you can type it in.
Period For Interest = 9 months
Period taken = 54 months
Investment = 2000
Quarters for payment = 54 ÷ 9
=6 periods
2000×2 = 4000
4000×2 = 8000
8000×2 = 16000
16000×2 = 32000
32000×2 = 64000
64000×2 = 128000
Answer = 128000
