A new physician saw 841 clients during the first year of practice and 1072 clients during the second year of the practice. Which of the following represents the approximate percentage increase in the client volume?

A. 22%

B. 27%

C. 127%

D. 78%

Answer Explanation:

Change in weight of client=new -old=1072-841= 231

Percent change=change/old*100%=231/841*100%=27.47%

The percentage change increase is about 27%

Therefore, the Correct Answer is B.

  • Q #1: Which of the following statements demonstrates a negative correlation between two variables?

    A. People who play baseball more tend to have more hits

    B. Shorter people tend to weigh less than taller people

    C. Tennis balls that are older tend to have less bounce

    D. Cars that are older tend to have higher mileage

    Answer Explanation

    A negative correlation means as one variable increases, the other variable decreases or as one variable decreases, the other variable increases. Based on this definition, we analyze the given statement as follows:

    People who play baseball more tend to have more hits is POSITIVE CORRELATION

    Shorter people tend to weigh less than taller people is a POSITIVE CORRELATION

    Tennis balls that are older tend to have less bounce is a NEGATIVE CORRELATION

    Cars that are older tend to have higher mileage is a POSITIVE CORRELATION

  • Q #2: A consumer recently purchased a new car and paid $48,000. This amount is $2,000 less than twice what the consumer’s friend paid for their car. Which of the following is the amount that the friend paid for their car?

    A. $23,000

    B. $46,000

    C. $25,000

    D. $50,000

    Answer Explanation

    Let the amount the friend pays be x. Then, 2 times what the friend pays is 2x. Less $2,000 what the friend pays is 2x-2000.

    Now we know that

    2x-2000=48000

    Add 2000 to both sides of the equation

    2x-2000+2000=48000+2000

    2x+2000-2000=50000

    2x=50000

    Divide both sides by 2

    X=25000

    Thus, the friend pays $25,000 for their car.

  • Q #3: What is the least common denominator for the fractions below? (Round the answer to the nearest integer) 1/2, 2/3, 4/5

    A. 30

    B. 25

    C. 7

    D. 19

    Answer Explanation

    We determine least common denominator (LCD) using prime factorization of denominators as follows

    2=1*2

    3=1*3

    5=1*5

    Thus, LCD of 2, 3, 5 = 2*3*5=30
