Q41.
If the salary of a person is first increased by 15% and thereafter decreased by 12%, what is the net change in his salary?
यदि किसी व्यक्ति के वेतन में पहले 15% की वृद्धि की जाती है और उसके बाद 12% की कमी की जाती है, तो उसके वेतन में कुल (शुद्ध) परिवर्तन क्या है?
  1. A1.4% decrease1.4% कमी
  2. B1.2% increase1.2% वृद्धि
  3. C1.32% decrease1.32% कमी
  4. D1.2% decrease1.2% कमी
Show answer

Concept: Net change for successive changes a% and b% is a+b+ab100.

  1. a=+15, b=−12.
  2. Net =15−12+15×(−12)100=3−1.8=1.2.
  3. Positive sign means an increase of 1.2%.

Trick: Multiply factors: 1.15×0.88=1.012, i.e. +1.2%.

Answer: (B) 1.2% increase

अवधारणा: क्रमिक परिवर्तन a% और b% का शुद्ध परिवर्तन a+b+ab100 होता है।

  1. a=+15, b=−12।
  2. शुद्ध =15−12+15×(−12)100=3−1.8=1.2।
  3. धनात्मक चिह्न यानी 1.2% की वृद्धि।

ट्रिक: गुणनखंड गुणा करें: 1.15×0.88=1.012, यानी +1.2%।

उत्तर: (B) 1.2% वृद्धि

Q71.
What should come in place of '?' in the given series based on the English alphabetical order?
GJE ZCX SVQ LOJ ?
अंग्रेज़ी वर्णमाला क्रम के आधार पर दी गई शृंखला में '?' के स्थान पर क्या आना चाहिए?
GJE ZCX SVQ LOJ ?
  1. AEHC
  2. BBFU
  3. CLNJ
  4. DPRN
Show answer

Concept: Check each position of the clusters separately for a constant jump in the alphabet (A=1 … Z=26, cyclic).

  1. 1st letters: G → Z → S → L : each −7 (G(7)−7 = 0 → Z(26)). Next: L(12)−7 = 5 → E.
  2. 2nd letters: J → C → V → O : each −7. Next: O(15)−7 = 8 → H.
  3. 3rd letters: E → X → Q → J : each −7. Next: J(10)−7 = 3 → C.

Trick: Subtracting 7 is the same as adding 19; when you go below A, add 26 and continue.

Answer: (A) EHC

अवधारणा: क्लस्टर के प्रत्येक स्थान के अक्षर को अलग-अलग देखें और वर्णमाला में स्थिर अंतर (A=1 … Z=26, चक्रीय) खोजें।

  1. पहले अक्षर: G → Z → S → L : हर बार −7 (G(7)−7 = 0 → Z(26))। अगला: L(12)−7 = 5 → E।
  2. दूसरे अक्षर: J → C → V → O : हर बार −7। अगला: O(15)−7 = 8 → H।
  3. तीसरे अक्षर: E → X → Q → J : हर बार −7। अगला: J(10)−7 = 3 → C।

ट्रिक: 7 घटाना = 19 जोड़ना; A से नीचे जाने पर 26 जोड़कर आगे बढ़ें।

उत्तर: (A) EHC
