MCQs (Multiple Choice Questions)

1)  The value of all assets that are reasonably expected to be converted in to cash with in one year in the normal course of business are called:

    a)        Liabilities 

    b)        Current assets 

    c)        Face value

Correct Answer:

The correct answer is  'b'.

Explanation:

Current assets are assets that are expected to be converted into cash within one year in the normal course of business. This includes cash, cash equivalents, accounts receivable, inventory, marketable securities, and prepaid expenses. Current assets are important because they provide a company with the resources it needs to meet its short-term obligations, such as paying salaries and bills.

2)  If the price of shoes increase from Rs.600 to 900, what is the percentage increase? 

    a)        (600/3)% 

    b)        (900/6)% 

    c)        (600/9)% 

    d)        (300/6)% 

Correct Answer: 

The correct answer is  'd'.

Explanation:

To calculate the percentage increase when the price of shoes increases from Rs. 600 to Rs. 900, you can use the following formula:

Percentage Increase = [(New Price - Old Price) / Old Price] * 100

In this case:

Percentage Increase = [(900 - 600) / 600] * 100

Percentage Increase = (300 / 600) * 100

Percentage Increase = 0.5 * 100

Percentage Increase = 50%

So, the correct answer is:

d) (300/6)%.

3)   Suppose A is a set with m elements and B is a set with n elements. How many functions are there from A to B?

    a)        m.n 

    b)       `n^m`

    c)        m.m

    d)        n.n

Correct Answer: 

The correct answer is  'b'.

Explanation:

For each element of set A, we have n choices for how to map it to an element of set B. Therefore, the total number of functions from A to B is n multiplied by itself m times, which is n^m.

4)  Determine the range of  the function g from X = {2,4,5} to Y = { 1,2,4,6} defined as g ={(2,6),(4,2),(5,1)}

    a)        Range of  g ={1,2,6} 

    b)        Range of  g ={2,6}

    c)         Range of  g ={2,4,5}

Correct Answer: 

The correct answer is  'a'.

Explanation:

To determine the range of the function g from X = {2, 4, 5} to Y = {1, 2, 4, 6}, defined as g = {(2, 6), (4, 2), (5, 1)}, you need to find all the values of Y that are associated with the elements of X based on the function g.

The range of the function g is the set of all the second components (y-values) in the ordered pairs of g. In this case, the range of g is:

Range of g = {1,2,6}.

5)    If set A has m elements and set B has n elements then the total numbers of relation from A to B are: 

    a)        m x n

    b)        `2^(m * n)`

    c)        m + n

    d)       mn

Correct Answer: 

The correct answer is  'b'.

Explanation:

The total number of relations from set A to set B is determined by the number of ordered pairs you can form between the elements of the two sets.

Set A has m elements, and set B has n elements. For each element in set A, you can pair it with any element in set B, or you can choose not to pair it with any element in set B. This leads to 2 choices (pairing or not pairing) for each element in set A.

Since there are m elements in set A, you have 2 choices for the first element, 2 choices for the second element, and so on, resulting in a total of `2^m` choices for set A. Similarly, there are `2^n` choices for set B.

To find the total number of relations, you multiply these choices together:

Number of relations = `2^m * 2^n` = `2^(m * n)`.

6)     The chart below is a …..graph

    a)        Pie

    b)        Bar

    c)        Line

    d)        Quadratic

Correct Answer: 

The correct answer is  'b'.

Explanation:

A bar chart (aka bar graph, column chart) plots numeric values for levels of a categorical feature as bars. Levels are plotted on one chart axis, and values are plotted on the other axis. Each categorical value claims one bar, and the length of each bar corresponds to the bar's value.

7)  The probability of sure event is

    a)        0

    b)        1

    c)        0.5

Correct Answer: 

The correct answer is  'b'.

Explanation:

In probability theory, an event with a probability of 1 is considered a certainty or a sure event because it is guaranteed to happen.

8)    The probability of tail when a coin is tossed is 

    a)        0

    b)        1

    c)        `1/2`

Correct Answer: 

The correct answer is  'c'.

Explanation:

In a fair coin toss, there are two equally likely outcomes: head or tail. Each of these outcomes has a probability of 1/2, making the total probability 1. So, the probability of getting a tail is 1/2.

9)    A major disadvantage of mean is that it is affected by

    a)        Extremely  large values

    b)        Extremely small values

    c)        Middle values

Correct Answer: 

The correct answer is  'c'.

Explanation:

The mean, or average, is sensitive to extreme values, particularly extremely large values, which can significantly skew the result. This is because the mean involves summing all the values and dividing by the number of values, so outliers have a significant impact on the result.

10)    Mode is the measure which always exists in any numerical data

    a)        True

    b)        False

Correct Answer: 

The correct answer is  'b'.

Explanation:

The mode is not guaranteed to exist in any set of numerical data. It is possible for a dataset to have multiple modes, one mode, or no mode at all. A dataset with no repeating values or where all values occur with the same frequency will have no mode. So, the statement is false.
