A.400
B.500
C.600
D.1500​

Answer 1

Answer:

Answer-B 500 please mark as brainliest and follow me

Step-by-step explanation:

Here, P is principal, r is rate of interest and t is time in years. Substitute 10000 for P, 5 for r and 1 for t in equation (1) to obtain the interest at the end of one year. Thus, the interest at the end of the one year is Rs. 500.

Answer 2

Answer:

option b 500

Step-by-step explanation:

Complete step-by-step answer:

The formula for simple interest is shown below.

Simple interest = P⋅r⋅t100......(1)Simple interest = P⋅r⋅t100......(1)

Here, PP is principal, rr is rate of interest and tt is time in years.

Substitute 10000 for PP, 5 for rr and 1 for tt in equation (1) to obtain the interest at the end of one year.

Simple interest = (10000)⋅(5)⋅(1)100⇒Simple interest = 50000100⇒Simple interest = 500Simple interest = (10000)⋅(5)⋅(1)100⇒Simple interest = 50000100⇒Simple interest = 500

Thus, the interest at the end of the one year is Rs.500.

Note: When the principal is invested at some interest rate, for some period of time, always use a simple interest formula.
