Answer: Let's assume that the marked price of the watch is M.
The discount amount would be 20% of M, which can be calculated as:
0.2 * M = 0.2M
The selling price after the discount would be:
M - 0.2M = 0.8M
The VAT amount would be 13% of the selling price after the discount, which can be calculated as:
0.13 * 0.8M = 0.104M
Now, as the discount amount is Rs.192 more than the VAT amount, we can write an equation:
0.2M = 0.104M + 192
0.096M = 192
M = 192 / 0.096 = 2000
So, the marked price of the watch is Rs.2000 and the selling price after the discount and VAT is 0.8M = 0.8 * 2000 = 1600.

Three vertices of a parallelogram are located at (-4, 3), (1, -2), and (-1, 4). What are
two possible locations of the fourth vertex? Explain your reasoning.
The two possible locations of the fourth vertex are (4, -1) and (-6, 9). The solution has been obtained by using the properties of parallelogram.
What is a parallelogram?
A parallelogram has two sets of parallel sides, making it a quadrilateral. A parallelogram's opposing sides and angles are both the same length.
Finding the vector that depicts the shift from one of the given vertices to another is necessary in order to determine the fourth vertex of a parallelogram.
The third given vertex must then be added to the vector.
We know that the opposite sides of a parallelogram are parallel and equal in length, we may determine the coordinates of the other two vertices by adding the same displacement vector to two of the given vertices.
The difference between the first and second provided vertices i.e.
(1 - (-4), -2 - 3), is one potential displacement vector which is (5, -5).
On adding this vector to the third vertex, we get the fourth vertex as (4,-1).
Similarly, the difference between the second and third vertices i.e.
(-1 - 1, 4 - (-2)) is another potential displacement vector which is (-2, 6).
On adding this vector to the third vertex, we get the fourth vertex as
(-6, 9).
Hence, the two possible locations of the fourth vertex are (4, -1) and
(-6, 9).

The nutrition information on the cereal box says that a 1/2-cup serving provides 210 calories and 9 grams of dietary fiber. At that rate, find how many calories and grams of fiber are in a 2/3-cup serving.
Answer:
Step-by-step explanation:
To find the number of calories and grams of fiber in a 2/3-cup serving, we can simply multiply the values for a 1/2-cup serving by the appropriate factor. A 2/3-cup serving is 1.5 times larger than a 1/2-cup serving, so we multiply the calorie and fiber content by 1.5.
210 calories * 1.5 = 315 calories
9 grams of fiber * 1.5 = 13.5 grams of fiber
So a 2/3-cup serving would contain 315 calories and 13.5 grams of fiber.

Sheet Metal Trades To determine the average thickness of a metal sheet, a Sheet metal worker measures it at five different locations. Her measurements are 0.0401, 0.0417, 0.0462, 0.0407, and 0.0428 in. What is the average thickness of the sheet?
The average thickness of the metal sheet is 0.0423 inches.
What do you mean by average?In statistics, the mean is a measure of central tendency of a set of data. It is also referred to as the arithmetic mean and is calculated by adding up all the values in the data set and dividing by the total number of values.
Mean = (sum of all values) / (number of values)
For example, suppose we have the following set of data: 5, 7, 9, 11, 13. To find the mean, we add up all the values and divide by the total number of values, which is 5 in this case:
Mean = (5 + 7 + 9 + 11 + 13) / 5
Mean = 9
Therefore, the mean of this data set is 9.
The mean is a commonly used measure of central tendency because it takes into account all the values in the data set and is sensitive to changes in the data. However, it can be affected by outliers or extreme values in the data set, which can skew the results.
To find the average thickness of the sheet, we need to add the five measurements together and then divide by 5 (the number of measurements):
Average thickness = (0.0401 + 0.0417 + 0.0462 + 0.0407 + 0.0428) / 5
Average thickness = 0.0423 in
Therefore, the average thickness of the metal sheet is 0.0423 inches.
