- Q1
What is the formula for calculating simple interest?
I = PRT
I = P / (RT)
P = I + RT
P=I / (RT)
60s - Q2
If the principal is $500, the interest rate is 8%, and the time is 2 years, what is the simple interest?
$40
$80
$10
$20
30s - Q3
If the simple interest is $75, the principal is $1,500, and the time is 3 years, what is the interest rate?
4%
3%
2%
5%
30s - Q4
How is the principal calculated in the simple interest formula?
P = I / (RT)
P = I / T
P = I - RT
P = I / R
30s - Q5
If the principal is $2,000, the interest rate is 6%, and the interest is $240, what is the time?
3 years
5 years
4 years
2 years

$72
$36
$24
$18
30s - Q9
What is the formula for calculating the total amount (A) in the context of simple interest?
A = P + (PRT)
A = P - I
A = P(1 + RT)
A = P + I

$200
$250
$150
$300
30s - Q12
What happens to the simple interest if the principal increases?
Depends on the interest rate
