Sample GCE A/L Science for Technology Practice Questions

Try these sample questions to review concepts for the GCE A/L Science for Technology exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A technical workshop deposits LKR 150,000 into a commercial bank account offering a simple interest rate of 8% per annum. What is the total interest accrued at the end of 3 years?
A.LKR 12,000
B.LKR 24,000
C.LKR 36,000
D.LKR 48,000
Explanation: Simple interest is calculated using the formula I = (P * R * T) / 100. Substituting the principal P = 150,000, annual rate R = 8, and time T = 3 years gives I = (150,000 * 8 * 3) / 100 = 36,000. Therefore, the total simple interest accrued over 3 years is LKR 36,000.
2A fabrication enterprise produces an agro-machinery component at a production cost of LKR 8,000 and sells it for LKR 10,000. What is the profit percentage based on the production cost?
A.25.0%
B.20.0%
C.16.7%
D.30.0%
Explanation: Profit is the selling price minus the cost price: 10,000 - 8,000 = LKR 2,000. The profit percentage on cost is (Profit / Cost Price) * 100 = (2,000 / 8,000) * 100 = 25.0%.
3An automated irrigation pump controller adjusts operating voltage according to the linear relationship 4V - 18 = 2V + 14. What is the equilibrium operating voltage V?
A.8 V
B.12 V
C.16 V
D.20 V
Explanation: Subtracting 2V from both sides gives 2V - 18 = 14. Adding 18 to both sides yields 2V = 32. Dividing by 2 gives V = 16 V.
4A concrete drainage canal has a trapezoidal cross-section with parallel horizontal top and bottom widths of 2.4 m and 1.6 m respectively, and a vertical depth of 1.2 m. What is the cross-sectional area of the canal?
A.2.00 m²
B.2.40 m²
C.2.88 m²
D.4.80 m²
Explanation: The cross-sectional area of a trapezoid is A = 0.5 * (a + b) * h. Substituting parallel side lengths a = 2.4 m, b = 1.6 m, and vertical height h = 1.2 m gives A = 0.5 * (2.4 + 1.6) * 1.2 = 0.5 * 4.0 * 1.2 = 2.40 m².
5A technician positions a surveying theodolite 30 m away from the base of a vertical cellular communications tower on level ground. The measured angle of elevation to the top of the tower is 30°. Given tan(30°) = 0.5774, what is the height of the tower above the instrument level?
A.17.32 m
B.25.98 m
C.51.96 m
D.60.00 m
Explanation: In a right-angled triangle, tan(θ) = Opposite / Adjacent. Here, tan(30°) = Height / 30 m, so Height = 30 * tan(30°) = 30 * 0.5774 = 17.32 m.
6A quality control inspector records the thicknesses (in mm) of five manufactured steel plates: 12.2, 12.4, 12.5, 12.7, and 13.2. What is the arithmetic mean thickness of the batch?
A.12.40 mm
B.12.50 mm
C.12.60 mm
D.12.70 mm
Explanation: The arithmetic mean is the sum of observations divided by the number of observations: (12.2 + 12.4 + 12.5 + 12.7 + 13.2) / 5 = 63.0 / 5 = 12.60 mm.
7The displacement s (in metres) of an automated trolley along a linear track is given as a function of time t (in seconds) by s(t) = 3t² + 4t + 5. What is the instantaneous velocity of the trolley at t = 3 seconds?
A.22 m s⁻¹
B.26 m s⁻¹
C.44 m s⁻¹
D.58 m s⁻¹
Explanation: Instantaneous velocity is the first time derivative of displacement: v(t) = ds/dt = d(3t² + 4t + 5)/dt = 6t + 4. At t = 3 s, v(3) = 6(3) + 4 = 18 + 4 = 22 m s⁻¹.
8A hardware supplier advertises a portable electric generator with a marked price of LKR 80,000. During an agricultural promotion, a trade discount of 15% is offered. What is the net purchase price of the generator?
A.LKR 12,000
B.LKR 68,000
C.LKR 72,000
D.LKR 76,000
Explanation: The trade discount amount is 15% of LKR 80,000: 0.15 * 80,000 = LKR 12,000. The net purchase price is Marked Price - Discount = 80,000 - 12,000 = LKR 68,000.
9A cooperative society invests LKR 200,000 in a fixed deposit account earning 10% annual interest compounded annually. What is the total compound amount accumulated at the end of 2 years?
A.LKR 220,000
B.LKR 240,000
C.LKR 242,000
D.LKR 244,000
Explanation: Compound amount is given by A = P * (1 + r/100)ⁿ. Here P = 200,000, r = 10, and n = 2 years. Therefore, A = 200,000 * (1.10)² = 200,000 * 1.21 = LKR 242,000.
10A workshop lathe machine purchased for LKR 500,000 depreciates by 10% per annum on a reducing balance basis. What is the book value of the lathe at the end of 2 years?
A.LKR 400,000
B.LKR 450,000
C.LKR 410,000
D.LKR 405,000
Explanation: Using reducing balance depreciation: V = P * (1 - r/100)ⁿ. After year 1: 500,000 * 0.90 = 450,000. After year 2: 450,000 * 0.90 = LKR 405,000. Alternatively, 500,000 * (0.90)² = 500,000 * 0.81 = LKR 405,000.
