Answer:
D) The amount that must be paid after a year is (d + 0.04 d)
Step-by-step explanation:
Here, Principal = d
Time =1 year
Rate of Interest = 4%
Now, SIMPLE INTEREST = [tex]\frac{P \times R \times T}{100}[/tex]
= [tex]\frac{d \times1 \times 4}{100} = 0.04d[/tex]
or, Simple Interest = 0.04d
Now, Amount = Principal + Simple Interest
= d + 0.04d
or, A = d + 0.04d
Hence, The amount that must be paid after a year is d + 0.04d
Answer : The correct options are, (A), (C) and (D)
Step-by-step explanation :
Given:
Principle = P = (d) dollars
Interest rate = R = 4 %
Time = T = 1 year
First we have to determine the simple interest.
Using simple interest formula:
[tex]S.I=\frac{PRT}{100}[/tex]
where,
P = principle
R = interest rate
T = time
S.I = simple interest
Now put all the given values in the above formula, we get:
[tex]S.I=\frac{d\times 4\times 1}{100}[/tex]
[tex]S.I=0.04d[/tex]
Now we have to determine the total amount.
Amount = Principle + Simple interest
Amount = d + 0.04d
Amount = 1.04 d
Amount = d + 1/25d
Thus, the correct options are, (A), (C) and (D)
