1📚Statistics & MathematicsStatistics

Consider the following statements regarding Measures of Mortality:

- a. Gross Reproduction Rate: 5. Measures the number of daughters over a lifetime.
- b. Age-Specific Fertility Rate: 3. Has modal value between 20 and 25
- c. Net Reproduction Rate: 2. Affected by mortality rates
- d. Maternal Mortality Rate: 4. Is measured per 1000 live births.

Which of the pairs given above is/are correctly matched?

Explanation

Matches: GRR (Gross Reproduction Rate) measures daughters born per woman without considering mortality (a-5). ASFR usually peaks in age group 20-25 (b-3). NRR is NRR = GRR * survival rate, hence affected by mortality (c-2). MMR in this specific matching maps to 4. Correct match is a-5, b-3, c-2, d-4.

صحیح جوڑے مندرجہ ذیل ہیں: GRR کا تعلق بیٹیوں کی پیدائش کی شرح سے ہے (a-5)؛ ASFR کا موڈل گروپ 20-25 عمر کے درمیان ہوتا ہے (b-3)؛ NRR پر شرح اموات اثر انداز ہوتی ہے (c-2)۔ یعنی آپشن C درست ہے۔

- T(20) + 6 = 26, R(18) + 6 = 24, A(1) + 6 = 7, C(3) + 6 = 9, T(20) + 6 = 26, O(15) + 6 = 21, R(18) + 6 = 24.
Applying +6 to JASMINE:
- J(10) + 6 = 16
- A(1) + 6 = 7
- S(19) + 6 = 25
- M(13) + 6 = 19
- I(9) + 6 = 15
- N(14) + 6 = 20
- E(5) + 6 = 11
Result: 16-7-25-19-15-20-11.

122📚Radio, Television & Educational Broadcasting (EDUSAT)Atmospheric Noise Immunity in FM

A radio station is experiencing poor signal quality due to atmospheric disturbances. Which type of radio broadcasting should they consider switching to for better quality?
A) AM radio
B) FM radio
C) SW radio
D) Ham radio

Explanation

FM (Frequency Modulation) radio is inherently resistant to amplitude-based atmospheric noise, lightning static, and electrical interference because signal information is encoded in frequency variations rather than amplitude levels.

FM (फ़्रीक्वेंसी मॉड्यूलेशन) रेडियो वायुमंडलीय बिजली और शोर से अप्रभावित रहता है क्योंकि इसमें जानकारी आवृत्ति के उतार-चढ़ाव में होती है, न कि आयाम (Amplitude) में। अतः स्पष्ट ध्वनि के लिए FM सबसे उपयुक्त है।

131📚General Mental Ability & ReasoningCoding & Decoding

In a code language, BLEND is written as ENHPG. How will WINNER be written in the same language?
A) ZKQPHT
B) ZKQPHU
C) YKQPHT
D) ZKOPHT

Explanation

Analyzing BLEND -> ENHPG:
B (2) + 3 = E (5)
L (12) + 2 = N (14)
E (5) + 3 = H (8)
N (14) + 2 = P (16)
D (4) + 3 = G (7)
The alternating shift pattern is +3, +2, +3, +2, +3, +2.
Applying to WINNER:
W (23) + 3 = Z (26)
I (9) + 2 = K (11)
N (14) + 3 = Q (17)
N (14) + 2 = P (16)
E (5) + 3 = H (8)
R (18) + 2 = T (20)
Thus, WINNER is coded as ZKQPHT.

कोडिंग पैटर्न में एकांतर क्रम में +3 और +2 का योग किया गया है:
B (+3)=E, L (+2)=N, E (+3)=H, N (+2)=P, D (+3)=G।
यही पैटर्न WINNER पर लागू करने पर:
W (+3) = Z
I (+2) = K
N (+3) = Q
N (+2) = P
E (+3) = H
R (+2) = T
अतः सही कोड ZKQPHT (विकल्प A) है।

132📚General Mental Ability & ReasoningMathematical Operations & Cipher

If 0 is to be replaced by 1, 1 is replaced by 2....... 7 is replaced by 8 and 8 is replaced by 9 and 9 is replaced by 0. Then answer the following question.
811 - 772 - 655 = ?
A) - 727
B) - 876
C) - 564
D) - 765

Explanation

According to the replacement cipher: each digit d becomes (d + 1) mod 10:
0->1, 1->2, 2->3, 3->4, 4->5, 5->6, 6->7, 7->8, 8->9, 9->0.
Converting the numbers in the expression:
- 811 becomes 922
- 772 becomes 883
- 655 becomes 766
Evaluating the expression:
922 - 883 - 766
= 922 - (883 + 766)
= 922 - 1649 = -727.

प्रतिस्थापन नियम के अनुसार प्रत्येक अंक d अपने अगले अंक (d + 1) में बदल जाता है (तथा 9 बदलकर 0 हो जाता है):
811 -> 922
772 -> 883
655 -> 766
समीकरण का मान = 922 - 883 - 766 = 922 - 1649 = -727।
अतः सही उत्तर -727 (विकल्प A) है।

134📚Basic Reasoning & Mental AbilityCoding-Decoding

In a certain code language 'PINKY' is coded as 'XZJLMOHJOQ'. How will 'VANDY' be coded in that language?
A) XZECMOBZUW
B) ZXCEMOZBWU
C) XZCEMOZBWU
D) XZCEMOZBUW

Explanation

The code takes the word in reverse order, and for each letter, outputs the predecessor and successor letters: Word PINKY reversed is Y-K-N-I-P. Y is flanked by X and Z (XZ); K by J and L (JL); N by M and O (MO); I by H and J (HJ); P by O and Q (OQ). Combining gives XZJLMOHJOQ. Now apply this pattern to VANDY: reverse is Y-D-N-A-V. Y -> XZ, D -> CE, N -> MO, A -> ZB, V -> UW. Combining gives XZCEMOZBWU.

शब्द को उलटे क्रम में लिखकर प्रत्येक अक्षर के ठीक पहले और बाद के अक्षर लिखे गए हैं: VANDY का उल्टा क्रम Y-D-N-A-V है। Y के लिए XZ, D के लिए CE, N के लिए MO, A के लिए ZB, V के लिए UW => XZCEMOZBWU। अतः विकल्प C सही है।

140📚Questioned Documents & InksCharred Document Decipherment

Which type of photography is used to decipher typewritten text on charred documents?

Explanation

Infrared (IR) photography or reflected infrared imaging (e.g. Video Spectral Comparator) is the primary technique used to decipher text on charred documents because carbon in inks reflects or absorbs IR radiation differently than charred paper.

झुलसे या जले हुए दस्तावेजों (Charred documents) पर लिखावट और टाइप किए गए पाठ को पढ़ने के लिए इन्फ्रारेड (IR) फोटोग्राफी का उपयोग किया जाता है क्योंकि कार्बन स्याही और जला हुआ कागज IR किरणों को अलग-अलग रूप में परावर्तित करते हैं।

141📚Questioned Documents & InksDecipherment of Obliterations

Obliteration can be best deciphered by using:

Explanation

Infrared (IR) radiation (reflected IR and infrared luminescence on a Video Spectral Comparator) is the premier non-destructive method for deciphering obliterations because the obliterating ink often transmits IR light while the underlying original writing absorbs it.

काटे गए या छुपाए गए लेख (Obliteration) को उजागर करने के लिए इन्फ्रारेड प्रकाश (IR light) सबसे प्रभावी है क्योंकि छुपाने वाली स्याही IR किरणों के प्रति पारदर्शी हो जाती है जबकि मूल लिखावट उसे अवशोषित कर लेती है।

155📚Basic Concepts of ComputersData Representation & Binary Arithmetic

Which of the following statements is/are correct?
I. Overflow in two's complement addition can be detected by examining only the carry out of the most significant bit.
II. When converting an unsigned integer to a larger type, zero extension is used to preserve its value.
III. In Binary-Coded Decimal (BCD) representation, each decimal digit is encoded separately using four binary bits.
IV. In a byte-addressable system, the effective address calculation is dependent on instruction length.

Choose the correct option:
A) Only IV is True
B) Only II and III are True
C) Only II and IV are True
D) Only III and IV are True

Explanation

Evaluating statements:
- Statement I is false: In two's complement addition, overflow occurs if and only if the carry-in into the sign bit differs from the carry-out from the sign bit (Cin XOR Cout = 1).
- Statement II is true: Widening an unsigned integer pads leading higher-order bits with zeros (zero-extension) to preserve numerical value.
- Statement III is true: BCD encodes each decimal digit (0–9) using its standard 4-bit binary nibble (e.g., 9 is 1001).
- Statement IV is false: Effective address calculation depends on the addressing mode and base/offset registers, not the instruction length.
Thus, only II and III are True.

कथन II और III सत्य हैं: अहस्ताक्षरित पूर्णांकों को बड़ा करने पर उच्च बिट्स में शून्य जोड़ा जाता है (शून्य विस्तार), और BCD में प्रत्येक दशमलव अंक 4 बाइनरी बिट्स द्वारा दर्शाया जाता है। कथन I गलत है क्योंकि ओवरफ्लो कैरी-इन और कैरी-आउट के अंतर पर निर्भर करता है। अतः विकल्प B सही है।

In a certain language, BRAIN is coded as TPKDC, then in that language, MINDS will be coded as
A) UPOKF
B) NPOKF
C) TPOKF
D) ZPOKF

Explanation

In BRAIN, each letter is shifted by +2 (B->D, R->T, A->C, I->K, N->P) and rearranged by placing the 2nd letter first (T), 5th second (P), 4th third (K), 1st fourth (D), 3rd fifth (C) giving TPKDC. For MINDS: shifting by +2 gives M->O, I->K, N->P, D->F, S->U. Placing the 5th letter first (U), 3rd second (P), 1st third (O), 2nd fourth (K), 4th fifth (F) gives UPOKF.

BRAIN के सभी अक्षरों में +2 जोड़ने पर {D, T, C, K, P} प्राप्त होता है और उन्हें TPKDC के रूप में पुनर्व्यवस्थित किया जाता है। MINDS में प्रत्येक अक्षर में +2 जोड़ने पर M+2=O, I+2=K, N+2=P, D+2=F, S+2=U आता है, जिसे व्यवस्थित करने पर UPOKF प्राप्त होता है।

162📚Basic ReasoningBlood Relations

Consider the following information and answer the given question:
M is the mother of N.
N is the brother of O.
O is the wife of P.
P is the son of Q.
How is O related to Q?
A) Grand Daughter
B) Mother
C) Daughter
D) Daughter-in-law

Explanation

P is the son of Q, and O is the wife of P. Therefore, O is the wife of Q's son, making O the daughter-in-law of Q.

P, Q का पुत्र है और O, P की पत्नी है। अतः O, Q के पुत्र की पत्नी है, जिसका अर्थ है कि O, Q की पुत्रवधू (Daughter-in-law) है।

163📚Basic ReasoningCoding-Decoding

In a certain code FIRE is coded as DGPC. What will be the last letter of the coded word for SHOT.

Explanation

In the code FIRE → DGPC, each letter is shifted backwards by 2 positions:
- F (6) - 2 = D (4)
- I (9) - 2 = G (7)
- R (18) - 2 = P (16)
- E (5) - 2 = C (3)
For the word SHOT, the last letter is T (20):
T (20) - 2 = R (18).
Thus, the last letter of the coded word is R.

FIRE → DGPC में प्रत्येक अक्षर को 2 स्थान पीछे खिसकाया गया है (-2):
- F - 2 = D, I - 2 = G, R - 2 = P, E - 2 = C।
शब्द SHOT का अंतिम अक्षर T (20) है:
T (20) - 2 = R (18)।
अतः कोडित शब्द का अंतिम अक्षर R (विकल्प B) होगा।

If SUMMER is coded RUNNER, the code for WINTER is

Explanation

Analyzing the shift from SUMMER to RUNNER:
- S - 1 = R
- U + 0 = U
- M + 1 = N
- M + 1 = N
- E + 0 = E
- R + 0 = R
Applying the identical pattern to WINTER:
- W - 1 = V
- I + 0 = I
- N + 1 = O
- T + 1 = U
- E + 0 = E
- R + 0 = R
The coded word is VIOUER.

SUMMER से RUNNER का पैटर्न:
- S (-1) = R, U (0) = U, M (+1) = N, M (+1) = N, E (0) = E, R (0) = R।
WINTER पर यही पैटर्न लागू करने पर:
- W (-1) = V, I (0) = I, N (+1) = O, T (+1) = U, E (0) = E, R (0) = R।
अतः कोडित शब्द VIOUER (विकल्प B) है।

165📚Basic ReasoningCoding-Decoding

If "TAPE" is coded as "SUZBOQDF" in a specific system, how would "MOCK" be coded using the same system?

Explanation

Each single letter is coded as the two letters immediately preceding and succeeding it (-1 and +1):
- T → S, U (SU)
- A → Z, B (ZB)
- P → O, Q (OQ)
- E → D, F (DF)
→ SUZBOQDF.
Applying the same rule to MOCK:
- M → L, N (LN)
- O → N, P (NP)
- C → B, D (BD)
- K → J, L (JL)
→ LNNPBDJL.

प्रत्येक अक्षर को उसके ठीक पहले और ठीक बाद वाले दो अक्षरों (-1 और +1) द्वारा कोडित किया गया है:
- T → S, U; A → Z, B; P → O, Q; E → D, F → SUZBOQDF।
MOCK के लिए:
- M → L, N (LN)
- O → N, P (NP)
- C → B, D (BD)
- K → J, L (JL)
→ LNNPBDJL (विकल्प D)।

166📚Basic ReasoningCoding-Decoding

In a certain code language, 'MOHAN' is coded as 39-45-24-3-42 and 'KABIR' is coded as 33-3-6-27-54. How will 'RAGHU' be coded in that language?

Explanation

Each letter's position in the alphabet is multiplied by 3:
- M (13×3=39), O (15×3=45), H (8×3=24), A (1×3=3), N (14×3=42)
- K (11×3=33), A (1×3=3), B (2×3=6), I (9×3=27), R (18×3=54)
For RAGHU:
- R = 18 × 3 = 54
- A = 1 × 3 = 3
- G = 7 × 3 = 21
- H = 8 × 3 = 24
- U = 21 × 3 = 63
Code is: 54-3-21-24-63.

प्रत्येक अक्षर के वर्णमाला क्रम को 3 से गुणा किया गया है:
- M (13×3=39), O (15×3=45), H (8×3=24), A (1×3=3), N (14×3=42)।
RAGHU के लिए:
- R: 18 × 3 = 54
- A: 1 × 3 = 3
- G: 7 × 3 = 21
- H: 8 × 3 = 24
- U: 21 × 3 = 63
अतः कोड 54-3-21-24-63 (विकल्प C) है।

A and B are brothers. C and D are sisters. A's son is D's brother. How is B related to C?

Explanation

Since A's son is D's brother, and C and D are sisters, A is the father of C, D, and the son. Since B is the brother of A, B is the paternal uncle of C.

चूँकि A का पुत्र D का भाई है और C तथा D बहनें हैं, इसलिए A, C और D का पिता है। B, A का भाई है, अतः B, C का चाचा (अंकल) है।

A is the mother of B. B is the sister of C. C is married to D. E is the son of D. How is A related to E?

Explanation

A is the mother of B and C (since B and C are sisters/siblings). C is married to D, and E is their son. Since A is the mother of E's mother C, A is the grandmother (maternal grandmother) of E.

A, B और C की माँ है। C और D का पुत्र E है। चूँकि A, E की माँ C की माँ है, इसलिए A, E की नानी (Grandmother) है।
