Amount borrowed = 400-75= 325.

Amount paid = 23*16+ 9 = 368+ 9 = 377

Interest Paid = 377-325 = 52

Required % age = 52 /325 *100% = (13*4)/(13*25) * 100 = 4*4 = 16%

400 - 75 = 325 (Amount borrowed)
Total amount paid = 23(16) + 9 = 377
Total interest = Amount Paid - Amount borrowed = 377 - 325 = 52
52/325 = 0.16 or 16%

Total amount borrowed = $400 - $75 = $325
Balance paid with interest = (23 * 16) + 9 = $377
Therefore, total interest paid = $377 - $325 = $52

Hence, required percentage = (52/325) * 100 = [spoiler]16%[/spoiler]

The correct answer is D.
