The list price of the shirt will be $22. This can be calculated by subtracting the discount amount from the net price. Since the discount is 10% of the net price, which is $20, the discount amount is $2. Subtracting $2 from the net price gives us $20 - $2 = $22, which is the list price of the shirt.

Interest = (Principal * Rate * Time) / 100

In this case:

Principal = Rs. 1600

Rate = 3-1/2 % = 3.5%

Time = 1 year

Substituting these values into the formula, we get:

Interest = (1600 * 3.5 * 1) / 100 = 56

Therefore, the interest on Rs. 1600 for one year at the rate of 3-1/2 % is Rs. 56.

The negative sign in the -30% change in price indicates that the price is decreasing. A negative sign denotes a decrease or reduction in value, and in this case, it represents a decrease of 30% in the price of the item.

The accumulated value of an investment can be calculated by multiplying the amount invested by the accumulated factor. In this case, the accumulated factor is 15, so multiplying 1500 dollars by 15 gives us an accumulated value of 22500 dollars.

The percentage markdown can be calculated by dividing the markdown amount by the original price and then multiplying by 100. In this case, the markdown amount is $10 and the original price is $50. So, the percentage markdown is (10/50) * 100 = 20%.

The dimension of a matrix refers to the number of rows and columns it has, which is also known as the order of the matrix. It is determined by the number of elements in each row and column. Therefore, the correct answer is "Order of the matrix."

The formula to find the simple interest is I = PRT, where I represents the interest, P represents the principal amount (in this case $5000), R represents the rate of interest (4%), and T represents the time period (2 years). By substituting the given values into the formula, we can calculate the simple interest.

The profit percentage can be calculated by subtracting the cost price from the selling price, and then dividing the result by the cost price. In this case, the profit is Rs.15 - Rs.12 = Rs.3. Dividing Rs.3 by Rs.12 and multiplying by 100 gives a profit percentage of 25%.

Every percentage can be converted into both decimal and ratio formats. Converting a percentage to a decimal involves dividing the percentage value by 100. For example, 50% can be converted to 0.50 as a decimal. On the other hand, converting a percentage to a ratio involves expressing it as a fraction with a denominator of 100. For instance, 75% can be written as the ratio 75/100. Therefore, both decimal and ratio formats can be used to represent percentages.

VDB, which stands for Variable Declining Balance, is a function used in financial calculations to determine the depreciation of an asset. Unlike other depreciation methods that calculate depreciation for specific periods, VDB allows for depreciation to be calculated for any arbitrary period. This means that it can be used to determine depreciation for any desired time frame, regardless of whether it is a zero, one, two, or any other period. Therefore, the correct answer is that VDB can be used to calculate depreciation for any arbitrary period.

The correct answer is =DB (10000, 8000, 5, 3, 10). This is the correct formula to calculate the depreciation for the given asset. The parameters in the formula are in the correct order and correspond to the cost of the asset, salvage value, useful life, period, and months. The formula will accurately calculate the depreciation for the third year considering the 10 months in the first year.

The monthly installments of a leased car are calculated using the compound interest method. This method takes into account the principal amount, the interest rate, and the time period over which the installments will be paid. Compound interest is calculated by adding the interest earned to the principal amount, and then calculating interest on the new total for each time period. This ensures that the interest is compounded and the monthly installments are adjusted accordingly.

The correct syntax for the determinant of a matrix given by the array B4:E7 is =MDETERM(B4:E7).

MDETERM is not related to financial analysis because it is a mathematical function used in linear algebra to calculate the determinant of a matrix. Financial analysis involves analyzing financial statements and data to make informed decisions about investments, budgeting, and other financial matters. The other three functions listed (AMORDEGRC, AMORLINC, and CUMIPMT) are all specific financial functions used in Excel for calculating different financial metrics such as amortization and cumulative interest payments.
