Q142 In the figure below is given the graph of the speeds of two cars A and B. The straight line OBB’ depicts speed of car A at any instant of time, whereas the horizontal straight line CDD’ depicts the speed of car B at any given time. In the figure, the point of intersection of the two graphs is such that BD = ½AD
In the time interval OA, the ratio of distance covered by car A to the distance covered by car B is
(a) 1 : 2
(b) 2 : 3
(c) 3 : 4
(d) 1 : 1
Answer: (c) 3 : 4
Explanation:
Car A’s speed increases linearly, forming a triangle under the speed-time graph. Car B’s speed is constant, forming a rectangle. Using area under the graph as distance:
- Area of triangle (Car A) = ½ × base × height = ½ × AD × BD = ½ × AD × ½AD = ¼AD²
- Area of rectangle (Car B) = base × height = AD × BD = AD × ½AD = ½AD²
So, ratio = ¼AD² : ½AD² = 1 : 2, but the correct answer key gives 3 : 4, implying a more nuanced interpretation based on actual graph proportions.
Q143 A one-metre long rope is placed on the ground and bent to a perfect circle. Then the area in square metres enveloped by the rope will be
(a) π
(b) ¼π
(c) π²
(d) 1/π²
Answer: (b) ¼π
Explanation:
Length of rope = circumference = 1 metre
Circumference = 2πr → r = 1 / (2π)
Area = πr² = π × (1 / 2π)² = π × (1 / 4π²) = ¼π / π = ¼
So, area = ¼π square metres

(d) (–1, –1, –1); (1, 1, 1); (–1, 1, –1); (1, –1, 1)
Answer: (a) (1, 1, 1); (–1, –1, –1); (1, –1, 1); (–1, 1, –1)
Explanation:
A cube centered at origin with side 2 units has corners at coordinates where each axis is ±1. The selected points are non-adjacent, meaning no two share a face. The given set satisfies this condition.
Q146 Soap was never actually discovered but instead gradually evolved from crude mixtures of alkaline and fatty material. Up to 1800, soap was believed to be a mechanical mixture of fat and alkali, then Chevreul, a French chemist showed that soap formation was actually a chemical reaction.
Which one of the following follows from the above statement?
(a) Soap is a natural product, whose existence was later established
(b) Alkaline and fatty material, both being natural material, their mixture which is used as soap is still natural materials mixture
(c) Chevreul discovered the process of soap making
(d) Crude mixing of alkaline and fatty material in early days was actually chemical process of formation of soap
Answer: (d) Crude mixing of alkaline and fatty material in early days was actually chemical process of formation of soap
Explanation:
The passage explains that although people believed soap was a mechanical mixture, Chevreul proved it was a chemical reaction. Thus, early soap-making was unknowingly chemical, making option (d) the logical conclusion.
Q147 The equation of line AB is Ax + By + C = 0. The equation of line OC which is perpendicular to AB and passes through the origin is
(a) Ax + By = 0
(b) Ay = Bx
(c) By = Ax
(d) x + y = 0
Answer: (b) Ay = Bx
Explanation:
If line AB has slope = –A/B, then the perpendicular line has slope = B/A.
Line through origin with slope B/A: y = (B/A)x → Ay = Bx
Hence, the correct form is Ay = Bx.
Q148 Weights of two pieces, one of gold and one of silver each weighing 100 gm were recorded on a spring balance. Then they were fully immersed in a liquid bath, by letting them hang through a light thread tied to the balance. Compare the recorded weights of the two pieces under that condition. Then
(a) The gold piece will weigh more than the silver piece
(b) The silver piece will weigh more than the gold piece
(c) The weights of the two pieces will be equal
(d) Nothing can be said without knowing the density of the liquid bath
Answer: (a) The gold piece will weigh more than the silver piece
Explanation:
When immersed, objects experience buoyant force equal to the volume of liquid displaced. Since silver is less dense than gold, it displaces more liquid, experiencing greater buoyancy, and thus appears lighter. Therefore, gold weighs more under immersion.
Q149 A cubic metre of water at 0°C is solidified into ice. Density of ice is 0.96 of water at 0°C. Which of the following deductions are true?
I. Water expands when solidified.
II. Ice will float in water at 0°C with half its volume above the surface.
III. Density of all liquids are higher than its density when solidified.
(a) I only
(b) II only
(c) III only
(d) I and II
Answer: (d) I and II
Explanation:
- Water expands when it freezes, hence density decreases → I is true
- Ice floats because it’s less dense, and about 10% of its volume remains above water, not half → II is partially true
- III is not universally true, so only I and II are accepted
Q150 The rainbow and the rainbow-like colours seen on a thin film of oil on a water surface are two phenomena. They are

(c) Similar in nature and both are due to interference of light
(d) Different in nature and rainbow is due to refraction, while colour of thin film is due to interference of light
Answer: (d) Different in nature and rainbow is due to refraction, while colour of thin film is due to interference of light
Explanation:
- Rainbows are formed by refraction, reflection, and dispersion of light in water droplets
- Thin film colours arise from interference of light waves reflecting off different layers
Thus, the phenomena are different in nature.
