• Question 2 of 5 2. Question A tank is fitted with two inlet pipes, D and E, having radii 3 cm and 6 cm, respectively. The rate of water flow through each pipe is directly proportional to the cube of its radius. If the pipe with the smaller radius takes 90 minutes to fill the empty tank, how much time will pipe E take to fill a tank that is already 20% full? (a) 9 minutes (b) 8 minutes (c) 12 minutes (d) 6 minutes Correct Answer: (a) Solution Water flow is directly proportional to the cube of the radius. Let k be the proportionality constant. Then, Pipe D (radius 3 cm) = k × 3³ = 27k units/minute Pipe E (radius 6 cm) = k × 6³ = 216k units/minute Pipe D has the smaller radius and it takes 90 minutes to fill the tank. Capacity of tank = flow rate × time = 27k × 90 = 2430k units The tank is already 20% full, so 80% remains to be filled: Remaining volume = 80% of 2430k = 0.8 × 2430k = 1944k units Time taken by pipe E to fill the remaining 80% of the tank = remaining volume / flow rate of E = 1944k / 216k = 9 minutes Hence, option (a) is correct. Incorrect Answer: (a) Solution Water flow is directly proportional to the cube of the radius. Let k be the proportionality constant. Then, Pipe D (radius 3 cm) = k × 3³ = 27k units/minute Pipe E (radius 6 cm) = k × 6³ = 216k units/minute Pipe D has the smaller radius and it takes 90 minutes to fill the tank. Capacity of tank = flow rate × time = 27k × 90 = 2430k units The tank is already 20% full, so 80% remains to be filled: Remaining volume = 80% of 2430k = 0.8 × 2430k = 1944k units Time taken by pipe E to fill the remaining 80% of the tank = remaining volume / flow rate of E = 1944k / 216k = 9 minutes Hence, option (a) is correct.
#### 2. Question
A tank is fitted with two inlet pipes, D and E, having radii 3 cm and 6 cm, respectively. The rate of water flow through each pipe is directly proportional to the cube of its radius. If the pipe with the smaller radius takes 90 minutes to fill the empty tank, how much time will pipe E take to fill a tank that is already 20% full?
• (a) 9 minutes
• (b) 8 minutes
• (c) 12 minutes
• (d) 6 minutes
Answer: (a)
Solution Water flow is directly proportional to the cube of the radius. Let k be the proportionality constant.
Then, Pipe D (radius 3 cm) = k × 3³ = 27k units/minute Pipe E (radius 6 cm) = k × 6³ = 216k units/minute
Pipe D has the smaller radius and it takes 90 minutes to fill the tank.
Capacity of tank = flow rate × time = 27k × 90 = 2430k units
The tank is already 20% full, so 80% remains to be filled: Remaining volume = 80% of 2430k = 0.8 × 2430k = 1944k units
Time taken by pipe E to fill the remaining 80% of the tank = remaining volume / flow rate of E = 1944k / 216k = 9 minutes
Hence, option (a) is correct.
Answer: (a)
Solution Water flow is directly proportional to the cube of the radius. Let k be the proportionality constant.
Then, Pipe D (radius 3 cm) = k × 3³ = 27k units/minute Pipe E (radius 6 cm) = k × 6³ = 216k units/minute
Pipe D has the smaller radius and it takes 90 minutes to fill the tank.
Capacity of tank = flow rate × time = 27k × 90 = 2430k units
The tank is already 20% full, so 80% remains to be filled: Remaining volume = 80% of 2430k = 0.8 × 2430k = 1944k units
Time taken by pipe E to fill the remaining 80% of the tank = remaining volume / flow rate of E = 1944k / 216k = 9 minutes
Hence, option (a) is correct.
• Question 3 of 5 3. Question In a college sports meet, each student participates in at least one of three games—cricket, football, or basketball—and no student participates in all three. If 80 students play cricket, 55 play football, 45 play basketball, and 30 students participate in exactly two games, then how many students are there in total? (a) 150 (b) 140 (c) 160 (d) 165 Correct Answer: (a) Solution Total number of students = number of students that participated in cricket number of students that participated in football number of students that participated in basketball – number of students that participated in exactly 2 games – 2 × number of students that participated in 3 games Given that no one participates in all three games, the last term is zero. Total students = 80 + 55 + 45 – 30 – (2 × 0) = 180 – 30 = 150 Hence, option (a) is correct. Incorrect Answer: (a) Solution Total number of students = number of students that participated in cricket number of students that participated in football number of students that participated in basketball – number of students that participated in exactly 2 games – 2 × number of students that participated in 3 games Given that no one participates in all three games, the last term is zero. Total students = 80 + 55 + 45 – 30 – (2 × 0) = 180 – 30 = 150 Hence, option (a) is correct.

• Question 5 of 5 5. Question In an age obsessed with constant connectivity, solitude is increasingly misunderstood as loneliness or social withdrawal. Yet solitude, when chosen rather than imposed, serves as a vital space for mental clarity and inner renewal. It allows individuals to disengage from external noise and reorient themselves toward their own thoughts, values, and aspirations. Without such pauses, one’s identity becomes entangled with the expectations and judgments of others. However, modern life often crowds out these reflective moments with endless distractions—notifications, conversations, and pressures to be constantly available. As a result, people may remain surrounded by interactions yet feel strangely disconnected from themselves. Solitude is not an escape from life; it is a return to one’s center. Societies that dismiss its importance risk producing individuals who are hyper-connected yet internally fragmented, active yet unanchored. True emotional balance requires not just social bonds, but also the courage to be alone. Q. Which of the following best captures the central idea of the passage? (a) Spending time alone weakens social relationships and emotional stability. (b) Solitude, when embraced consciously, is essential for self-understanding and inner balance. (c) Modern connectivity has eliminated the need for solitude in daily life. (d) People should reduce social interactions to avoid psychological stress. Correct Answer: (b) Explanation: (b) is correct: The passage clearly states that solitude is a space for clarity, renewal, and inner grounding, and that it is essential for emotional balance. (a) is incorrect: The passage distinguishes solitude from loneliness and does not claim it weakens relationships. (c) is incorrect: The passage warns that modern life disrupts solitude, not replaces its importance. (d) is too extreme and not supported; the passage values both solitude and social bonds. Thus, (b) best summarizes the central theme. Incorrect Answer: (b) Explanation: (b) is correct: The passage clearly states that solitude is a space for clarity, renewal, and inner grounding, and that it is essential for emotional balance. (a) is incorrect: The passage distinguishes solitude from loneliness and does not claim it weakens relationships. (c) is incorrect: The passage warns that modern life disrupts solitude, not replaces its importance. (d) is too extreme and not supported; the passage values both solitude and social bonds. Thus, (b) best summarizes the central theme.
