Step 1: Identify the given values. The bill amount (Principal) is Rs. 8000, the bankers' discount (BD) is Rs. 160, and the time until the bill is due is 2 months.
Step 2: Convert the time from months to years. Since the time is 2 months, we convert it to years: 2 months = 2/12 = 1/6 years.
Step 3: Use the formula for the rate of interest. The formula is Rate = (BD × 100) / (Principal × Time).
Step 4: Substitute the values into the formula. Rate = (160 × 100) / (8000 × 1/6).
