  1. ACOP27
  2. BCOP28
  3. CCOP29
  4. DCOP26
Show answer

Concept: The annual UN Climate Change Conference (COP) is numbered consecutively; the host changes every year.

  1. COP29 was held in Baku, Azerbaijan, 11–22 November 2024; it agreed a new climate-finance goal of US$300 billion a year by 2035.
  2. COP27 – Sharm el-Sheikh (2022); COP28 – Dubai (2023); COP26 – Glasgow (2021).

Yaad rakhein: Glasgow 26 → Sharm 27 → Dubai 28 → Baku 29 → Belém (Brazil) 30 in 2025.

Answer: (C) COP29

अवधारणा: संयुक्त राष्ट्र जलवायु सम्मेलन (COP) क्रमानुसार गिना जाता है; मेज़बान हर वर्ष बदलता है।

  1. COP29 बाकू, अज़रबैजान में 11–22 नवंबर 2024 को हुआ; इसमें 2035 तक US$300 बिलियन प्रतिवर्ष का नया जलवायु-वित्त लक्ष्य तय हुआ।
  2. COP27 – शर्म अल-शेख (2022); COP28 – दुबई (2023); COP26 – ग्लासगो (2021)।

याद रखें: ग्लासगो 26 → शर्म 27 → दुबई 28 → बाकू 29 → बेलेम (ब्राज़ील) 30 (2025)।

उत्तर: (C) COP29

Q41.
During a sale, 50% of the goods are sold at 21% profit, 40% of the remaining goods are sold at 36% profit and the still remaining goods are sold at a loss of 29%. If there is an overall profit of x%, then what is the value of x?
एक सेल के दौरान, 50% वस्तुएँ 21% लाभ पर बेची जाती हैं, शेष वस्तुओं का 40% भाग 36% लाभ पर बेचा जाता है और फिर भी बची हुई वस्तुएँ 29% हानि पर बेची जाती हैं। यदि कुल मिलाकर x% का लाभ होता है, तो x का मान क्या है?

  2. B8.5
  3. C9
  4. D9.5
Show answer

Concept: When parts of the stock are sold at different profit/loss rates, the overall profit % is the weighted average of the rates (weights = fraction of goods, since cost per unit is the same).

  1. Fractions: first 50%, then 40% of the remaining 50% = 20%, the rest = 30%.
  2. Overall profit =0.5×21+0.2×36−0.3×29=10.5+7.2−8.7=9.

Trick: Think of total cost as ₹100: profit = 10.5+7.2−8.7=9 rupees = 9% directly.

Answer: (C) 9

अवधारणा: जब माल के अलग-अलग हिस्से अलग लाभ/हानि पर बिकें, तो कुल लाभ % उन दरों का भारित औसत (weighted average) होता है (भार = माल का अंश)।

  1. अंश: पहले 50%, फिर बचे 50% का 40% = 20%, शेष = 30%।
  2. कुल लाभ =0.5×21+0.2×36−0.3×29=10.5+7.2−8.7=9।

ट्रिक: कुल लागत ₹100 मानें: लाभ = 10.5+7.2−8.7=9 रुपये = सीधे 9%।

उत्तर: (C) 9

Show answer

Concept: Compare corresponding letters of consecutive terms using positions A=1 … Z=26 (wrap around after A).

  1. F(6) → Y(25) → R(18) → K(11): each step −7 (6−7 = −1 → 25).
  2. C(3) → V(22) → O(15) → H(8): each −7. Z(26) → S(19) → L(12) → E(5): each −7.
  3. Next: K(11)−7 = D(4), H(8)−7 = A(1), E(5)−7 = −2 → 24 = X.

Trick: Going back 7 is the same as going forward 19; when the number goes below 1, add 26.

Answer: (A) DAX

अवधारणा: क्रमागत पदों के संगत अक्षरों की तुलना स्थान-संख्या A=1 … Z=26 से करें (A से पीछे जाने पर Z पर लौटें)।

  1. F(6) → Y(25) → R(18) → K(11): प्रत्येक चरण −7 (6−7 = −1 → 25)।
  2. C(3) → V(22) → O(15) → H(8): प्रत्येक −7। Z(26) → S(19) → L(12) → E(5): प्रत्येक −7।
  3. अगला: K(11)−7 = D(4), H(8)−7 = A(1), E(5)−7 = −2 → 24 = X।

ट्रिक: 7 पीछे जाना = 19 आगे जाना; संख्या 1 से कम हो जाए तो 26 जोड़ दें।

उत्तर: (A) DAX
