To find the rate percent per annum, we can use the formula for simple interest (SI): SI = (Principal × Rate × Time) / 100. Here, SI is Rs1680, Principal is Rs7000, and Time is 16 months (or 16/12 years = 4/3 years). Rearranging the formula to find Rate, we get Rate = (SI × 100) / (Principal × Time). Plugging in the values, Rate = (1680 × 100) / (7000 × 4/3) = 18%. Thus, the rate percent per annum is 18%.
To calculate the ordinary interest, use the formula: Interest = Principal × Rate × Time. Here, the principal is $1800, the rate is 12% (or 0.12), and the time is 2 months (which is 2/12 years). Thus, the interest is: Interest = $1800 × 0.12 × (2/12) = $36. So, the ordinary interest on $1800 for two months at a 12% rate is $36.
26.35 months.
42% of eight months is 3.36 months or three months and 11 days.
To find the total amount, you can use the formula: Total Amount = Principal + Interest. First, calculate the interest using the formula: Interest = Principal × Rate × Time (in months/12). Then, add the interest to the principal to get the total amount.
15% of 36 months is 5.4 months. (36 x 0.15)
.05% or 1/20th of a percent
To calculate the ordinary interest, use the formula: Interest = Principal × Rate × Time. Here, the principal is $1800, the rate is 12% (or 0.12), and the time is 2 months (which is 2/12 years). Thus, the interest is: Interest = $1800 × 0.12 × (2/12) = $36. So, the ordinary interest on $1800 for two months at a 12% rate is $36.

85% of 7 months is 5.95 months.
85% of 13 months is 11.05 months
To calculate 80 percent of 12 months, you would first convert 80 percent to a decimal by dividing by 100, resulting in 0.80. Then, you would multiply 0.80 by 12 to find the answer. Therefore, 80 percent of 12 months is 9.6 months.
