दिया गया है:

स्टेशन P से स्टेशन Q तक गति: 70 किमी/घंटा

स्टेशन Q से स्टेशन P तक गति: 90 किमी/घंटा

सूत्र:

औसत गति = 2xy/x + y

औसत गति = (2 × 70 × 90)/70 + 90 = 78.75 किमी/घंटा

इस प्रकार, पूरी यात्रा के दौरान बस की औसत गति 78.75 किमी/घंटा है।

Q8.Five jumbled up sentences, related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd one out and key in the number of the sentence as your answer: 1. Machine learning models are prone to learning human - like biases from the training data that feeds these algorithms. 2. Hate speech detection is part of the on - going effort against oppressive and abusive language on social media. 3. The current automatic detection models miss out on something vital: context. 4. It uses complex algorithms to flag racist or violent speech faster and better than human beings alone. 5. For instance, algorithms struggle to determine if group identifiers like "gay" or "black" are used in offensive or prejudiced ways because they're trained on imbalanced datasets with unusually high rates of hate speech.
Q9.The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage. Aesthetic political representation urges us to realize that ‘the representative has autonomy with regard to the people represented’ but autonomy then is not an excuse to abandon one’s responsibility. Aesthetic autonomy requires cultivation of ‘disinterestedness’ on the part of actors which is not indifference. To have disinterestedness, that is, to have comportment towards the beautiful that is devoid of all ulterior references to use – requires a kind of aesthetic commitment; it is the liberation of ourselves for the release of what has proper worth only in itself. 
Q10.The four sentences (labelled 1, 2, 3, 4) below, when properly sequenced would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer: 1. Complex computational elements of the CNS are organized according to a “nested” hierarchic criterion; the organization is not permanent and can change dynamically from moment to moment as they carry out a computational task. 2. Echolocation in bats exemplifies adaptation produced by natural selection; a function not produced by natural selection for its current use is exaptation -- feathers might have originally arisen in the context of selection for insulation. 3. From a structural standpoint, consistent with exaptation, the living organism is organized as a complex of “Russian Matryoshka Dolls” -- smaller structures are contained within larger ones in multiple layers. 4. The exaptation concept, and the Russian-doll organizat
