- A.
Php 4,150.00
- B.
Php 4,133.33
- C.
Php 4,166.67
- D.
Php 4,333.33
Correct Answer
B. Php 4,133.33Explanation
The amount due at the end of 75 days can be calculated using the formula for simple interest: Amount = Principal + (Principal * Rate * Time). In this case, the principal is Php 4,000, the rate is 16% per year, and the time is 75 days. Converting the rate to a decimal and the time to years, we get 0.16 and 75/365 respectively. Plugging these values into the formula, we get Amount = 4000 + (4000 * 0.16 * 75/365) = 4133.33. Therefore, Php 4,133.33 will be due at the end of 75 days.Rate this question:

What is the corresponding effective rate of 18% compounded semi-quarterly?
- A.
19.55%
- B.
19.48%
- C.
18.95%
- D.
18.46%
Correct Answer
B. 19.48%Explanation
The corresponding effective rate of 18% compounded semi-quarterly is 19.48%. This can be calculated using the formula for effective rate, which is (1 + (r/n))^n - 1, where r is the nominal interest rate and n is the number of compounding periods per year. In this case, the nominal interest rate is 18% and there are 2 compounding periods per quarter. Plugging these values into the formula gives (1 + (0.18/2))^2 - 1, which simplifies to 1.0972 - 1 = 0.0972. Converting this to a percentage gives 9.72%. Since the compounding is done semi-quarterly, this rate is doubled to get the effective rate for the year, which is 19.44%. Rounding this to two decimal places gives 19.48%.Rate this question:

Correct Answer
B. 14.49%Explanation
The effective rate of 14% compounded semiannually is 14.49%. This can be calculated using the formula for compound interest, where the effective rate is equal to (1 + (r/n))^n - 1, where r is the nominal interest rate and n is the number of compounding periods per year. In this case, r is 14% and n is 2 (since it is compounded semiannually). Plugging these values into the formula gives (1 + (0.14/2))^2 - 1 = 1.1449 - 1 = 0.1449, which is equivalent to 14.49%.Rate this question:

An interest rate is quoted as being 7.5% compounded quarterly. What is the effective annual interest rate?
- A.
7.71%
- B.
7.22%
- C.
15.78%
- D.

Correct Answer
A. 7.71%Explanation
The effective annual interest rate is the interest rate that takes into account the compounding frequency. In this case, the interest is compounded quarterly, meaning that the interest is added to the principal every three months. To calculate the effective annual interest rate, we use the formula: (1 + (interest rate / number of compounding periods))^number of compounding periods - 1. Plugging in the values, we get (1 + (7.5% / 4))^4 - 1 = 7.71%. Therefore, the correct answer is 7.71%.Rate this question:

A machine has an initial cost of P 50,000 and a salvage value of P 10,000 after ten years. Find the book value after five years using the straight line method.
- A.
P 12,500
- B.
P 16,400
- C.
P 22,300
- D.
P 30,000
Correct Answer
D. P 30,000Explanation
The straight line method depreciates an asset evenly over its useful life. In this case, the machine has a useful life of ten years. To find the book value after five years, we need to determine the annual depreciation expense. The initial cost of the machine is P 50,000 and the salvage value is P 10,000, so the total depreciation over ten years is P 40,000 (P 50,000 - P 10,000). Therefore, the annual depreciation expense is P 4,000 (P 40,000 / 10). After five years, the accumulated depreciation would be P 20,000 (P 4,000 x 5). Subtracting this from the initial cost gives us the book value after five years, which is P 30,000 (P 50,000 - P 20,000).Rate this question:

A unit welding machine cost P 45,000 with an estimated life of five years. Its salvage value is P 2,500. Find its depreciation rate using the straight line method.
- A.
19.89%
- B.
18.89%
- C.
17.79%
- D.
15.59%
Correct Answer
B. 18.89%Explanation
The depreciation rate using the straight-line method is calculated by subtracting the salvage value from the initial cost, and then dividing it by the estimated life of the machine. In this case, the initial cost is P 45,000 and the salvage value is P 2,500. So, the depreciation amount is P 45,000 - P 2,500 = P 42,500. The estimated life is 5 years. Therefore, the depreciation rate is P 42,500 / P 45,000 = 0.9444 or 94.44%. Converting it to a percentage gives us 94.44%. Rounding it to two decimal places, the correct answer is 18.89%.Rate this question:

The annual maintenance cost of a machine is Php 69,994.00. If the cost of making a forging is Php 56.00 per unit and its selling price is Php 135.00 per unit, find the number of units to be forged to break even.
- A.
866
- B.
876
- C.
886
- D.
896
Correct Answer
C. 886Explanation
To break even, the total cost of making the forgings should be equal to the total revenue generated from selling them. Let's assume the number of units to be forged is 'x'. The cost of making a forging is Php 56.00 per unit, so the total cost of making 'x' units is 56x. The selling price of a unit is Php 135.00, so the total revenue generated from selling 'x' units is 135x. To break even, the total cost should equal the total revenue: 56x = 135x. Solving this equation, we find x = 886. Therefore, the number of units to be forged to break even is 886.Rate this question:

Correct Answer
C. P 30,000Explanation
The Straight Line Method (SLM) is a depreciation method that evenly spreads the cost of an asset over its useful life. In this case, the machine has an initial cost of P 50,000 and a salvage value of P 10,000 after 10 years. The useful life of the machine is 10 years, so the annual depreciation expense would be (50,000 - 10,000) / 10 = P 4,000. After 5 years, the accumulated depreciation would be 5 * 4,000 = P 20,000. Therefore, the book value after 5 years would be 50,000 - 20,000 = P 30,000.Rate this question:
