Given :

A credit card company requires that its customers choose a 3 digit.

Each digit should be chosen from 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9.

So there are 10 possibilities for each digit.

To Find :

How many different three digit codes are there.

Solution :

We know, possibility of choosing each digit is 10.

So, total number of three digit codes are :

T=10\times 10\times 10\\\\T=1000

Therefore, their are 1000 different three digit codes.

Hence, this is the required solution.

Peter borrowed a sum of R12 850.00 at the beginning of a year with a certain simple interest rate. After 14 quarters, in a diffe
ladessa [460]

The original annual simple interest rate, rounded to two decimal places, is 3.79%

What is the formula for simple interest?

The simple interest on a loan or deposit is determined as the principal multiplied by the simple interest rate and time

I=PRT

The first loan:

P=12 850.00

R=r(assume it is r)

T=4 years

I=12 850.00*r*4

I=51400r

The second loan was taken after 14 quarters the first was taken out, which is the same as after 3.5 years, hence, the interest on the second loan is only for a half a year

P=3 273.00

R=0.5r( half of the interest on the first loan)

T=0.5 years

I=3 273.00*0.5r*0.5

I= 818.25r

Total interest=51400r+818.25r

Total interest=52218.25r

total interest paid=1 980.00

1 980.00=52218.25r

r=1 980.00/52218.25

r=3.79%
