Question

Solve the problems.

Answer 1

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:

where,

P = principle  

R = interest rate

T = time

S.I = simple interest

Now put all the given values in the above formula, we get:

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)

Answer 2

Answer:

A 1.04d

Step-by-step explanation:

The amount of the loan (d) must be paid, along with the interest (0.04d).

d + 0.04d = 1.04d
