Sample questions from this paper

Q1.
Three of the following letter-clusters are alike in some manner and one is different. Select the one that is different.
निम्नलिखित चार अक्षर-समूहों में से तीन किसी प्रकार से एकसमान हैं और एक उनसे असंगत है। उस असंगत अक्षर-समूह का चयन कीजिए।
  1. ANQST
  2. BGTHS
  3. CPSUV
  4. DSVXY
Show answer

Concept: Find the gap between consecutive letters of each cluster.

  1. NQST: N →+3 Q →+2 S →+1 T
  2. PSUV: P(+3)S(+2)U(+1)V; SVXY: S(+3)V(+2)X(+1)Y
  3. GTHS: G → T is +13, which breaks the +3,+2,+1 pattern.

Trick: Write alphabet positions: N=14, Q=17, S=19, T=20 – the gaps 3,2,1 are visible at once.

Answer: (B) GTHS

अवधारणा: प्रत्येक समूह में क्रमागत अक्षरों का अंतर देखें।

  1. NQST: +3,+2,+1
  2. PSUV और SVXY: दोनों में +3,+2,+1
  3. GTHS: G → T में +13 – यह पैटर्न से अलग है।

ट्रिक: अक्षरों की स्थिति लिखें (N=14, Q=17…), अंतर तुरंत दिख जाएगा।

उत्तर: (B) GTHS

  1. ये पीर पंजाल श्रेणी के ढलानों पर, Kashmir Himalayas में मिलते हैं।
  2. एक प्राचीन झील के सूखने पर ये निक्षेप बचे रह गए।
  3. करेवा केसर (zafran), बादाम और अखरोट की खेती के लिए प्रसिद्ध हैं।

Q101.
The total surface area of a square-based right pyramid is 1536 m2, of which 37.5% is the area of the base of the pyramid. What is the volume (in m3) of this pyramid?
वर्गाकार आधार वाले एक लंब पिरामिड का कुल पृष्ठीय क्षेत्रफल 1536 m2 है, जिसका 37.5% पिरामिड के आधार का क्षेत्रफल है। इस पिरामिड का आयतन (m3 में) कितना है?
  1. A3048
  2. B3072
  3. C3144
  4. D3108
Show answer

Concept: For a square-based pyramid: TSA=a2+2al, h=l2−(a2)2, V=13a2h (l = slant height of a face).

  1. Base area =37.5% of 1536=576m2, so side a=24m.
  2. Lateral area =1536−576=960=2×24×l, so l=20m.
  3. Height h=202−122=256=16m.
  4. V=13×576×16=3072m3.

Trick: 37.5%=38; 38×1536=576 instantly. (12, 16, 20) is the 3-4-5 triple ×4.

Answer: (B) 3072

अवधारणा: वर्गाकार आधार वाले पिरामिड में: TSA=a2+2al, h=l2−(a2)2, V=13a2h (l = तिर्यक ऊँचाई / slant height)।

  1. आधार का क्षेत्रफल =1536 का 37.5%=576m2, अतः भुजा a=24m।
  2. पार्श्व क्षेत्रफल =1536−576=960=2×24×l, अतः l=20m।
  3. ऊँचाई h=202−122=16m।
  4. आयतन V=13×576×16=3072m3।

ट्रिक: 37.5%=38; (12, 16, 20) त्रिक = (3, 4, 5) × 4।

उत्तर: (B) 3072

Q151.
Select the most appropriate synonym of the given word.
Spontaneous
  1. AAttractive
  2. BExhaustive
  3. CInstinctive
  4. DAcquisitive
Show answer

Concept: Spontaneous means done naturally, without planning or outside prompting.

  1. Instinctive = arising from natural impulse, not from thought – same sense.
  2. Attractive = pleasing; Exhaustive = complete/thorough; Acquisitive = eager to gain possessions – none fits.

Yaad rakhein: Spontaneous laughter = instinctive laughter – it just comes out by itself.

Answer: (C) Instinctive

अवधारणा: Spontaneous का अर्थ है स्वाभाविक रूप से, बिना योजना के होने वाला (स्वतःस्फूर्त)।

  1. Instinctive = सहज प्रवृत्ति से होने वाला – यही अर्थ।
  2. Attractive = आकर्षक, Exhaustive = संपूर्ण, Acquisitive = संग्रह का लालची – मेल नहीं खाते।

याद रखें: Spontaneous laughter = instinctive laughter – अपने-आप निकलने वाली हँसी।

उत्तर: (C) Instinctive
