UPSC Civil Services (Preliminary) Examination 2016, General Studies Paper II (CSAT), Question 54 — Puzzles, arrangements & general mental ability.

आगे आने वाले 3 (तीन) प्रश्नांशों के लिए निर्देश : निम्नलिखित सूचना पर विचार कीजिए और आगे दिए गए तीन प्रश्नांशों के उत्तर दीजिए।

जब तीन मित्र A, B और C, मिले, तो पाया गया कि उनमें से प्रत्येक ने एक भिन्न रंग की ऊपरी पोशाक पहन रखी थी। यादृच्छिक क्रम में वे पोशाकें जैकेट, स्वेटर और टाई हैं; और रंग नीला, सफेद और काला है। उनके कुलनाम (सरनेम) यादृच्छिक क्रम में रिबीरो, कुमार और सिंह हैं।

आगे, यह ज्ञात है कि :

1. न तो B ने, न ही रिबीरो ने सफेद स्वेटर पहना था

2. C ने टाई पहनी थी

3. सिंह की पोशाक सफेद नहीं थी

4. कुमार जैकेट नहीं पहनता

5. रिबीरो को काला रंग पहनना पसंद नहीं है

6. हर एक मित्र ने केवल एक ही रंग की एक ही ऊपरी पोशाक पहनी थी

Read this question in English

Direction for the following 3 (three) items: Consider the given information and answer the three items that follow.

When three friends A, B and C met, it was found that each of them wore an outer garment of a different colour. In random order, the garments are: jacket, sweater and tie; and the colours are: blue, white and black. Their surnames in random order are: Ribeiro, Kumar and Singh.

Further, we know that:

1. neither B nor Ribeiro wore a white sweater

2. C wore a tie

3. Singh's garment was not white

4. Kumar does not wear a jacket

5. Ribeiro does not like to wear the black colour

6. Each of the friends wore only one outer garment of only one colour

What is C's surname?

(a) Ribeiro · (b) Kumar · (c) Singh · (d) Cannot be determined

उत्तर और व्याख्या · explanation in English

Answer: (a) रिबीरो

Only A can have worn the white sweater (B is excluded and C wore the tie), so A is Kumar. 'Neither B nor Ribeiro' shows B is not Ribeiro, so B is Singh and C is Ribeiro.

  1. Clue 1 speaks of a white sweater worn by someone other than B and Ribeiro; it also tells us B is not Ribeiro.
  2. C wore the tie (clue 2), so the white sweater was A's.
  3. A is not Ribeiro (clue 1) and not Singh (clue 3), so A is Kumar — who indeed wears no jacket (clue 4).
  4. B wore the jacket. B is not Ribeiro, so B is Singh and C is Ribeiro.

Remember · 'Neither X nor Y' in a clue means X and Y are different people — a quiet but decisive fact in surname puzzles.
