1)   A manuscript of 7950 words was distributed to two typists A and B with a typing speed of 15 words/minute and 20 words/minute respectively. Typist A stops the work exactly after 1 hour 30 minutes. If so, how much time is required for typist B to finish the remaining work?

A) 4 hours

B) 3 hours 30 minutes

C) 3 hours 40 minutes

D) 5 hours 30 minutes

Typist A works for 1 hour 30 minutes (90 minutes) at 15 words/min: 15 × 90 = 1350 words.

Typist B works alongside A for the first 90 minutes at 20 words/min: 20 × 90 = 1800 words.

Total typed together in 90 minutes: 1350 (A) + 1800 (B) = 3150 words.

Remaining words = 7950 - 3150 = 4800 words.

Typist B must now type the remaining words alone at 20 words/min: 4800 / 20 = 240 minutes = 4 hours.

Ans)   A) 4 hours.


2)    Assertion (A): New Education Policy 2020 proposes to test the students’ critical thinking, rationalization, and creativity with the practical application of their knowledge.

Reason (R): The Policy proposes the creation of the National Research Foundation as an apex body for fostering a strong research culture and building research capacity.

A)   Both (A) and (R) are true and (R) is the correct explanation of (A).

B)   Both (A) and (R) are true but (R) is not the correct explanation of (A).

C)   (A) is true but (R) is false.

D)   (A) is false but (R) is true.

Assertion (A) is true: The New Education Policy (NEP) 2020 emphasizes testing students' critical thinking, rationalization, creativity, and the practical application of knowledge. This is a key feature of NEP 2020 which encourages experiential and inquiry-based learning for holistic student development.​

Reason (R) is also true: The NEP 2020 proposes the creation of the National Research Foundation to foster a strong research culture and build research capacity.​

(R) does not directly explain (A); the creation of the National Research Foundation is related to research culture, not directly to the methods for testing students' critical thinking and practical application.

Ans)   B) Both (A) and (R) are true but (R) is not the correct explanation of (A).
