Explanation
The series seems to be decreasing, and the differences between the numbers appear to be 1, 2, 3, and 4 successively. Hence, it's following a pattern where the differences between consecutive numbers are increasing by 1 each time. Starting from 25 and decreasing by 1, 2, 3, and 4 successively, the next number would decrease by 5. Therefore, if we continue this pattern, the next number in the series would be: 15 - 5 = 10

Explanation
The snake is least like the other four animals because it is a reptile, whereas the cow, tiger, dog, and bear are all mammals. Mammals have characteristics like warm-bloodedness, fur or hair, and they usually give live birth, whereas reptiles like snakes are cold-blooded, have scales, and typically lay eggs.

Explanation
Among the given options, the apple is the least like the other four because it is a fruit, while the potato, carrot, bean, and corn are all vegetables. Fruits typically develop from the flower of a plant and contain seeds, whereas vegetables are other edible parts of plants, such as roots, stems, and leaves. This botanical distinction makes the apple different from the other listed items.

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.

Explanation
The relationship between brother and sister is a sibling relationship. Similarly, the relationship between niece and nephew is also a sibling relationship, as they are the children of siblings. Therefore, the best comparison for niece is nephew.

Explanation
E is the only vowel in the group, making it different from the other four letters (F, C, D, Z), which are all consonants. While F, C, D, and Z share the characteristic of being consonants, E stands out as the sole vowel. This distinction in letter type—vowel versus consonant—makes E the least like the others in the set.

Explanation
Milk is commonly served in a glass, similarly, a letter is commonly placed inside an envelope. Both the glass and the envelope serve as containers for their respective items. Therefore, the best comparison is between milk and glass, and letter and envelope.

Explanation
The analogy in this question is based on the parts that make up the given objects. In a light bulb, the filament is a crucial component that produces light when electricity passes through it. Similarly, in a wheel, the spoke is a crucial component that connects the hub to the rim, providing support and stability. Therefore, the correct answer is "Spoke" as it is the part of the wheel that serves a similar function as the filament in a light bulb.

Explanation
If two people can make two bicycles in 2 hours, it means that each person can make one bicycle in 2 hours. In six hours, a person will make 6/2= 3 bicycles. To make 12 bicycles in 6 hours number of people needed will be= total number of bicycles/number of bicycles made by one person in 6 hours= 12/3= 4. 

Explanation
A solicitor is someone who acts as an advisor, providing legal guidance. Similarly, a sycophant is someone who acts as a fawner, excessively flattering or behaving obsequiously toward someone, typically to gain favor. The other options do not match the relationship in the same way.

Explanation
In the given question, the pattern is that each letter in the first set is repeated the same number of times as its corresponding number in the second set. In the first set, C is repeated 3 times, A is repeated 1 time, and C is repeated 2 times, which corresponds to the numbers 3, 1, and 3 in the second set. Similarly, in the second set, C is repeated 3 times, A is repeated 1 time, and C is repeated 2 times, which corresponds to the numbers 3, 1, and 3 in the answer choice 31311313. Therefore, the answer is 31311313.

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.

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.

Explanation
Brass is the only option that is an alloy, whereas the other four options are all individual elements.

Explanation
Let's work backward from the information provided:
Mary now has 5 cookies left.
Before giving half to her brother, she had 5 + 5 = 10 cookies (since she gave half to her brother).
Before eating one cookie and then giving half to her brother, she had 10 + 1 = 11 cookies.
Before giving half to her sister, she had 11 + 11 = 22 cookies (since she gave half to her sister).
Thus, Mary started with 22 cookies.

Explanation
The pattern in the sequence is that each number increases by consecutive even numbers:
2 + 4 = 6
6 + 6 = 12
12 + 8 = 20
20 + 10 = 30
30 + 12 = 42
So, the next number in the sequence is 42.

Explanation
All months have at least 28 days, as the shortest month, February, has 28 days in a non-leap year. Therefore, all 12 months have 28 days or more.
