What is the formula to calculate simple interest?

P × R × T

Explanation

Principal multiplied by rate multiplied by time.

If the principal is $1000, the rate is 5%, and the time is 2 years, what is the simple interest?

$200

Explanation

Simple interest is calculated using the formula: P × R × T.

Which of the following formulas correctly represents the calculation of simple interest?

I = P × R × T

Explanation

Simple interest is calculated using the formula: Principal multiplied by rate multiplied by time.

If the principal is $4000, the rate is 6%, and the time is 3 years, what is the simple interest?

$740

Explanation

Simple interest is calculated using the formula: P × R × T.

What is the formula to calculate the total amount (A) when interest is compounded annually?

A = P × (1 + R)^T

Explanation

Total amount is calculated using the formula for compound interest.

What happens to the simple interest when the time period increases?

Increases

Explanation

Simple interest increases as the time period increases.

A sum of money doubles itself in 5 years at a certain rate of simple interest. In how many years will it triple itself at the same rate?

20 years

Explanation

For money to triple at the same rate, it takes three times the time it takes to double, hence 20 years.

What is the principal amount if the simple interest accrued on $2000 at a rate of 8% per annum for 3 years is $480?

$2400

Explanation

Principal can be calculated using the formula: P = I / (R × T).

If $5000 is invested at an interest rate of 6% per annum compounded annually, how much will it amount to after 3 years?

$5,950

Explanation

Use the formula for compound interest: A = P × (1 + R)^T.

#10

At what annual rate of interest will a sum of money double itself in 10 years?

10%

Explanation

The rate can be calculated using the formula: Rate = 100 × (Time / Principal).

#11

Which of the following will result in the highest simple interest earned on a principal amount over a 5-year period?

7% per annum compounded monthly

Explanation

Compounding interest more frequently results in higher interest earned.
