Question 1 of 5
1. Question
If 3 ≤ x ≤ 9 and 1 ≤ y ≤ 5, then what is the ratio of maximum value of (x − y) to minimum value of (x + y)?
Correct
Answer: (a)
Explanation:
Maximum value of (x − y) occurs when x = 9 and y = 1.
So, max (x − y) = 9 − 1 = 8.Minimum value of (x + y) occurs when x = 3 and y = 1.
So, min (x + y) = 3 + 1 = 4.Required ratio = 8 / 4 = 2.
Incorrect
Answer: (a)
Explanation:
Maximum value of (x − y) occurs when x = 9 and y = 1.
So, max (x − y) = 9 − 1 = 8.Minimum value of (x + y) occurs when x = 3 and y = 1.
So, min (x + y) = 3 + 1 = 4.Required ratio = 8 / 4 = 2.

Question 2 of 5
2. Question
In an entrance test, 30% of the candidates were boys and 70% were girls. 60% of boys and 40% of girls cleared the preliminary test. In the final test, 70% of boys and 50% of girls (who cleared prelim) were successful. Which of the following is correct?
Correct
Answer: (a)
Solution:
Assume total = 1000 ⇒ Boys = 300, Girls = 700.
Prelim clears: Boys = 300×0.60 = 180; Girls = 700×0.40 = 280.
Final clears: Boys = 180×0.70 = 126; Girls = 280×0.50 = 140.
Success rates: Boys = 126/300 = 42%; Girls = 140/700 = 20%.
Overall = (126+140)/1000 = 266/1000 = 26.6% (not below 25%).
Also, more girls cleared (140 > 126).
Hence only (a) is correct.Incorrect

Also, more girls cleared (140 > 126).
Hence only (a) is correct. -
Question 3 of 5
3. Question
A trader sells two watches at the same price. On one he gains 25% and on the other he loses 25%. What is his overall result?
Correct
Answer: (c)
Solution:
Let selling price (SP) of each watch = 100.
Total SP = 200.First watch (25% gain):
CP = 100 × 100/125 = 80Second watch (25% loss):
CP = 100 × 100/75 = 133.33Total CP = 80 + 133.33 = 213.33
Loss = 213.33 − 200 = 13.33
% loss = (13.33 / 213.33) × 100 = 6.25% loss
Incorrect
Answer: (c)
Solution:
Let selling price (SP) of each watch = 100.
Total SP = 200.First watch (25% gain):
CP = 100 × 100/125 = 80Second watch (25% loss):
CP = 100 × 100/75 = 133.33Total CP = 80 + 133.33 = 213.33
Loss = 213.33 − 200 = 13.33
% loss = (13.33 / 213.33) × 100 = 6.25% loss

Question 4 of 5
4. Question
School education systems in many countries have introduced standardized testing to assess learning outcomes and compare institutional performance. Such assessments are often used to guide policy decisions, allocate resources, and identify areas requiring improvement. Supporters argue that standardized evaluations promote accountability and help maintain minimum academic benchmarks.
At the same time, critics note that excessive emphasis on test scores may narrow classroom instruction. Teachers may feel pressured to prioritize examination-oriented content over exploratory learning, discussion, and creative activities. Students, in turn, may come to associate education primarily with performance metrics rather than intellectual curiosity. Moreover, variations in socio-economic background, language environment, and parental support are not always adequately reflected in standardized results.
If assessment systems are applied without sufficient flexibility and contextual awareness, they may distort educational priorities instead of strengthening them.
Which one of the following statements best reflects the most logical and rational message conveyed by the author of the passage?
Correct
Answer: (b)
Explanation:
Option (b) is correct because the passage recognizes the role of standardized tests but stresses the need for flexibility and contextual awareness to avoid narrowing educational priorities.Option (a) is incorrect since the author does not oppose testing itself.
Option (c) contradicts the concern about narrowing instruction.
Option (d) overstates the limitations discussed in the passage.Incorrect

Question 5 of 5
5. Question
With reference to the above passage, the following assumptions have been made:
- Teaching practices are influenced by the way students are evaluated.
- Standardized test results fully represent students’ learning capacities.
Which of the above assumptions is/are valid?
Correct
Answer: (a)
Explanation:
Assumption I is valid. The passage notes that teachers may adjust instruction in response to testing pressure, implying a link between evaluation methods and teaching practices.Assumption II is invalid. The passage highlights socio-economic and contextual factors that are not adequately reflected in test results, rejecting the idea of complete representation.
Hence, only assumption I is valid.
