Answer Choices: (A) 337 (B) 268 (C) 198 (D) 620 (E) 168 Let's program in Python in the response.### Response: # Given, Simple Interest = Rs.900, Time = 9 years, Rate = 5% per annum
# We know that Simple Interest = (Principal * Rate * Time) / 100
# So, Principal = (Simple Interest * 100) / (Rate * Time)
principal = (900 * 100) / (5 * 9)
print(principal)
