Nia, twelve years old, is three times as old as her sister. How old will Nia be when she is twice as old as her sister?
A.
15
B.
18
C.
16
D.
20
E.
21
Correct Answer C. 16
Explanation Nia is currently 12 years old and three times as old as her sister, who is 12/3 = 4 years old. To find out when Nia will be twice as old as her sister, we need to determine the age difference between them. Currently, Nia is 12 - 4 = 8 years older than her sister. This age difference will remain constant as they both age. Therefore, when Nia is 16 years old, her sister will be 16 - 8 = 8 years old, making Nia twice as old as her sister. Thus, the correct answer is 16.

Jack is taller than Peter, and Bill is shorter than Jack.
Which of the following statements would be more accurate?
A.
Bill is as tall as Peter.
B.
It is impossible to tell whether Bill or Peter is taller.
C.
Bill is taller than Peter.

Correct Answer B. It is impossible to tell whether Bill or Peter is taller.
Explanation Based on the given information, we know that Jack is taller than Peter and Bill is shorter than Jack. However, we do not have any direct comparison between Bill and Peter. Therefore, we cannot determine whether Bill is taller than Peter, Peter is taller than Bill, or if they are of the same height. Hence, the most accurate statement is that it is impossible to tell whether Bill or Peter is taller.

The price of an article was cut by 20% for sale. By what percent must the discounted item be increased to again sell the article at the original price?
A.
15%
B.
20%
C.
25%
D.
30%
E.
35%
Correct Answer C. 25%
Explanation If an item’s price was reduced by 20%, it means it’s now being sold at 80% of its original price. To get back to the original price, the discounted price needs to be increased by a certain percentage.
Let’s denote the original price as ( P ), and the discounted price as ( D ). We have:
( D = P - 0.20P = 0.80P )
We want to find out by what percent ( D ) must be increased to get back to ( P ). Let’s denote this percentage as ( x ). So we have:
( D + xD = P )
Substituting ( D = 0.80P ) into the equation gives:
( 0.80P + 0.80Px = P )
Solving for ( x ) gives:
( x = \frac{P - 0.80P}{0.80P} = 0.25 )
So, the discounted item must be increased by 25% to again sell the article at the original price.

Mary had several cookies. After eating one, she gave half the remainder to her sister. After eating another cookie, she gave half of what was left to her brother. Mary now had only five cookies left. How many cookies did she start with?
A.
11
B.
23
C.
13
D.
45
E.
46
Correct Answer B. 23
Explanation 1. Let C represent the total number of cookies Mary started with.
2. After eating one cookie, she had (C - 1) cookies left.
3. After giving half to her sister, she had (C - 1)/2 cookies left.
4. After eating another cookie, she had ((C - 1)/2) - 1 cookies left.
5. After giving half to her brother, she had (((C - 1)/2) - 1)/2 cookies left, which equals 5.
Now, we can set up an equation:
(((C - 1)/2) - 1)/2 = 5
Let's solve for C:
(((C - 1)/2) - 1)/2 = 5
C = 23
Mary started with 23 cookies.
