Find the difference between the simple interest and compound interest on 16000 for 3/2 years at 5 %per annum, compound interest being reckoned half yearly.

16000((1+.05/2)^3 - 1 - .05*3/2) = 30.25

Now, if you meant 3 1/2 years, fix it up.

To find the difference between the simple interest and compound interest, we need to calculate the simple interest and compound interest separately.

First, let's calculate the simple interest using the formula: Simple Interest = (Principal * Rate * Time) / 100.

Principal = $16,000
Rate = 5% per annum
Time = 3/2 years = 1.5 years

Simple Interest = (16000 * 5 * 1.5) / 100 = $1,200

Now, let's calculate the compound interest, which is compounded half-yearly. The formula for compound interest is:

Compound Interest = Principal * (1 + Rate / n)^(n * Time) - Principal

Where n represents the number of compounding periods per year.

Given that the compound interest is reckoned half-yearly, the number of compounding periods per year (n) = 2.

Compound Interest = 16000 * (1 + 0.05 / 2)^(2 * 1.5) - 16000

Compound Interest = 16000 * (1.025)^3 - 16000

Compound Interest ≈ $1,241.35

Now we can calculate the difference between the simple interest and compound interest.

Difference = Compound Interest - Simple Interest

Difference = $1,241.35 - $1,200

Difference ≈ $41.35

Therefore, the difference between the simple interest and compound interest on $16,000 for 3/2 years at 5% per annum, compounded half-yearly, is approximately $41.35.

To find the difference between the simple interest and compound interest on a given principal amount, you need to calculate both the simple interest and compound interest separately.

First, let's calculate the simple interest.

Simple Interest (SI) = (Principal * Rate * Time) / 100

Where:
Principal = 16000
Rate = 5%
Time = 3/2 years

SI = (16000 * 5 * (3/2)) / 100
SI = 1200

Now, let's calculate the compound interest. Since the interest is compounded semi-annually, we will need to split the time period into two halves (6 months each).

Compound Interest (CI) = P * [(1 + r/n)^(n*t) - 1]

Where:
P = Principal
r = Rate / 100
n = Number of compounding periods per year
t = Total number of years

Principal = 16000
Rate = 5%
Time = 3/2 years (or 1.5 years)
Compounding periods per year = 2 (since interest is compounded half-yearly)

CI = 16000 * [(1 + 0.05/2)^(2*1.5) - 1]
CI = 16000 * (1.025)^3 - 1
CI ≈ 16000 * 1.0770388 - 1
CI ≈ 17232.62 - 1
CI ≈ 17231.62

Now, let's find the difference between the compound interest and simple interest.

Difference = Compound Interest - Simple Interest
Difference = CI - SI
Difference = 17231.62 - 1200
Difference ≈ 16031.62

Therefore, the difference between the simple interest and compound interest on 16000 for 3/2 years at 5% per annum (compounded semi-annually) is approximately 16031.62.
