Q. A merchant bought a batch of goods for $500 and sold them for $600. If he had given a discount of 10% on the selling price, what would be his profit?
Q. A metal block of mass 2 kg at 100°C is placed in 1 kg of water at 20°C. What is the final temperature of the system? (Specific heat of water = 4.2 J/g°C, Specific heat of metal = 0.9 J/g°C)
A.
30°C
B.
40°C
C.
50°C
D.
60°C
Solution
Using conservation of energy: m1*c1*(T1-Tf) = m2*c2*(Tf-T2). Solving gives Tf = 50°C.
Q. A metal rod is heated at one end. If the temperature at the heated end is 100°C and the other end is at 20°C, what is the temperature gradient along the rod?
A.
80°C/m
B.
20°C/m
C.
10°C/m
D.
5°C/m
Solution
Temperature gradient = (T_hot - T_cold) / Length. Assuming length is 8 m, gradient = (100°C - 20°C) / 8 m = 10°C/m.
Q. A metal rod of length 1 m and cross-sectional area 1 cm² is heated at one end. If the temperature difference between the ends is 100°C, what is the rate of heat transfer through the rod? (Thermal conductivity of the metal = 200 W/m°C)
A.
200 W
B.
400 W
C.
600 W
D.
800 W
Solution
Using Fourier's law: Q/t = kA(ΔT/L) = 200 W/m°C * 0.0001 m² * (100°C/1 m) = 200 W.
Q. A mixed graph shows the profit margins of four products (M, N, O, P) over two years. If Product M had a profit margin of 15% in Year 1 and 20% in Year 2, what is the increase in profit margin?
Q. A mixed graph shows the profit margins of three companies (A, B, C) over two years. If Company A had a profit margin of 15% in Year 1 and 20% in Year 2, what was the increase in profit margin?
A.
5%
B.
10%
C.
15%
D.
20%
Solution
The increase in profit margin for Company A is 5%.
Q. A mixture consists of 40% red paint and 60% blue paint. If 5 liters of blue paint is added, what will be the new percentage of red paint if the total volume becomes 25 liters?
A.
20%
B.
25%
C.
30%
D.
35%
Solution
Initial red paint = 40% of 20 liters = 8 liters. New total = 25 liters. New percentage of red = (8/25) * 100 = 32%.
