Q26

Read the following passage and answer the questions from 26 to 30: [Note: this is a paraphrased summary of the original passage, not a verbatim reproduction, since the source is an excerpt from a specific published memoir.] The narrator, APJ Abdul Kalam, recalls a colleague named Arun Tiwari, who had worked in his laboratory since 1982. Their bond deepened in February 1987, when Kalam visited Tiwari in a coronary care unit in Hyderabad, where Tiwari was recovering from a serious heart-related illness. Tiwari asked only for Kalam's blessing, hoping to live long enough to complete one of his projects. He recovered within a month and went on to play a key role in completing the airframe of the Akash missile, a task finished in three years. Afterward, Tiwari spent a year turning Kalam's own recollections into a connected narrative, eventually helping write Kalam's autobiography, weaving in pieces of poetry Kalam had marked in his personal reading over the years. Kalam frames the resulting book as more than a personal memoir -- as an account of Indian science's broader struggle to become self-reliant. He closes by describing himself as a believer who sees his scientific achievements, and the people who helped him along the way, as expressions of a higher purpose rather than his own doing alone.

Q62

A व B या दोन राशीतील संबंधाचे वर्णन करणारा उचित पर्याय निवडा. लाल्यू आणि जॉन हे रस्ता शर्यतीच्या स्पर्धेत धावत आहेत. लाल्यू 2 तासात 3/4 शर्यत पूर्ण करतो. लालूला 9/10 शर्यत पूर्ण करायला लागणाऱ्या वेळेच्या 5/8 वेळेत जॉन 2/3 शर्यत पूर्ण करतो. राशी A लाल्यूचा वेग राशी B जॉनचा वेग (1) दोन्ही राशी समान आहेत (2) राशी A लहान आहे (3) राशी B लहान आहे (4) राशीतील संबंध निश्चित करण्याच्या दृष्टीने माहिती पुरेशी नाही Select the appropriate option that describes the relation between quantities A and B. Lalu and John are competing in a road race. Lalu completes 3/4th of the race in 2 hours. John completes 2/3rd of the race in 5/8th of the time which Lalu takes to complete 9/10th of the race. Quantity A Lalu's Speed Quantity B John's Speed (1) Both the quantities are equal (2) Quantity A is smaller (3) Quantity B is smaller (4) Information is insufficient for determining the relation

1)दोनों राशी समान आहेत / Both the quantities are equal

2)राशी A लहान आहे / Quantity A is smaller&check; Correct

3)राशी B लहान आहे / Quantity B is smaller

4)राशीतील संबंध निश्चित करण्याच्या दृष्टीने माहिती पुरेशी नाही / Information is insufficient for determining the relation

Lalu's speed (Quantity A) = (3/4) / 2 = 3/8. For John, time taken by Lalu for 9/10th of race is (9/10) / (3/8) = 12/5 hours. John's time is 5/8 of this = 3/4 hours. John covers 2/3 of race in 3/4 hours, so John's speed = (2/3) / (3/4) = 8/9. Comparing 3/8 and 8/9, Quantity A is smaller.

Q66

एका रांगेमध्ये 'A' डाव्या बाजूने 11 व्या स्थानावर आहे आणि 'B' उजव्या बाजूने 10 व्या स्थानावर आहे. जर 'A' आणि 'B' यांच्या जागांची अदलाबदल केली तर 'A' डाव्या बाजूने 18 व्या स्थानावर येतो. तर या रांगेमध्ये 'A' आणि 'B' खेरीज किती व्यक्ती असतील?

1)27

2)26

3)25&check; Correct

4)24

After interchanging, A's new position from the left is 18th. Since B was originally 10th from the right, total persons in the row = (A's new position from left) + (B's original position from right) - 1 = 18 + 10 - 1 = 27. Persons between A and B (excluding A and B) = Total - 2 = 27 - 2 = 25.

Q67

रीना ने व्याजाच्या दराइतक्या वर्षांसाठी सरळ व्याजाने ₹ 1200 कर्ज घेतले जर तिने कर्ज फेडताना ₹ 432 व्याज दिले तर व्याजाचा दर किती होता ?

1)3.6

2)6&check; Correct

3)18

4)20

Let rate be R% and time be R years. Simple Interest formula is (P * R * T) / 100 = SI. Here, 1200 * R * R / 100 = 432 => 12 * R² = 432 => R² = 36 => R = 6.

Q68

जर a 60% b आहे, b 40% c आहे, c 20% d आहे, तर 6d हे 20a च्या किती टक्के आहे ?

1)550

2)500

3)600

4)625&check; Correct

Express 'a' in terms of 'd' using the given percentages: a = 0.6b, b = 0.4c, c = 0.2d. Thus, a = 0.6 * 0.4 * 0.2 * d = 0.048d. We need to find what percentage 6d is of 20a, which is (6d / 20a) * 100. Substituting a = 0.048d gives (6 / (20 * 0.048)) * 100 = 625%.
