सही उत्तर है - “अपना दोष छिपाने के लिए औरों में कमी दिखाना”।

• ‘नाच न जाने आँगन टेढ़ा’ लोकोक्ति का अर्थ ‘अपना दोष छिपाने के लिए औरों में कमी दिखाना’ होगा।
• वाक्य प्रयोग - ​वह सब से कहती फिरती है कि वह नृत्य में माहिर है। जब उसे नृत्य करने के लिए कहा गया तो अपने पैर में मोच बता कर बहाना बना दिया। इसे कहते हैं नाच न जाने आंगन टेढ़ा।

Additional Information 

• अर्थ को पूरी तरह स्पष्ट करने वाला वाक्य लोकोक्ति कहलाता है। लोकोक्ति को कहावतें भी कहते हैं।
• कहावतें कही हुई बातों के समर्थन में होती है। महापुरुषों, कवियों व संतों के कहे हुए ऐसे कथन जो स्वतंत्र और आम बोलचाल की भाषा में कहे गए हैं

The correct answer is 'Option 4'.

Key Points

• The word "unique" is an absolute term, meaning something is one of a kind.
• ​Never use a comparative or superlative degree (most) with 'unique'.
• Hence, the use of 'most' is inappropriate here and it must be removed and also 'the' must be added before 'unique' to make the sentence grammatically correct.

Hence, the correct answer is:  This is the unique thing I have ever seen in my life.

Additional Information 

• Never use comparatives or superlatives with these adjectives:
• Unique
• Supreme
• Impossible
• Vacuum
• Empty
• Everlasting
• Perfect
• Final
• Last

Given:

x and y are two positive numbers such that when x is reduced by 2 and y is increased by 2 , the ratio becomes 2 ∶ 1; and when x is increased by 2 and y is reduced by 2 , the ratio becomes 3 ∶ 1.

Calculation:

According to the question,

⇒ $\dfrac{x-2}{y+2} = \dfrac{2}{1}$    

⇒ x - 2 = 2y + 4

⇒ x = 2y + 6       →   (1)

⇒ $\dfrac{x+2}{y-2} = \dfrac{3}{1}$   

⇒ x + 2 = 3y - 6

⇒ x = 3y - 8   →   (2)

On putting the value of x from eq(1) in eq(2),

⇒ 2y + 6 = 3y - 8

⇒ y = 14

⇒ x = 2(14) + 6 = 34

⇒ x - y = 34 - 14 = 20

∴ x - y = 20

The correct answer is γ - radiations.

Key Points

• The penetration power of alpha, beta, and gamma radiations vary greatly of which gamma radiations have the highest penetrating power.
• They are the most difficult to stop and can be blocked only by lead, concrete, or another heavy shielding.
• Alpha radiations can be blocked easily even with a few pieces of paper.
• Beta radiations can be stopped by aluminium foil but pass through the paper.

The correct answer is option 2

Key Points

• The Param Vir Chakra (PVC) is India's highest military decoration, awarded for displaying distinguished acts of valor during wartime.
• This award can be given to an individual more than once in his/her lifetime. Hence option 1 is incorrect.
• On its medal, four replicas of ‘Indra Vajra’ are embossed. Hence option 2 is correct.
• The Param Vir Chakra is not just handed out on a silver platter. It’s such a rare honor, that only 21 people have ever been awarded one till 31^st December 2021, Two-thirds of them posthumously. Hence option 3 is incorrect.
• On 26 January 1950, celebrated as Republic Day of India, the Param Vir Chakra was instituted as a Gallantry Medal with retrospective effect from 15 August 1947 by Dr. Rajendra Prasad, the then President of India. Hence option 4 is incorrect.
• The Medal translates as the "Wheel of the Ultimate Brave", and the award is granted for "most conspicuous bravery in the presence of the enemy".

• ‘वि’ का अर्थ – हीनता, असमानता।​

Additional Information

The correct answer is "endurance."

Key Points

• 'Endurance' refers to the ability to withstand an unpleasant or difficult process or situation without giving way.
• In the context of a marathon, it denotes the capacity to sustain the extended physical exertion required.
• Therefore, the completed sentence reads: "Without good endurance, it's difficult to complete the marathon."

Hence, the correct answer is "Option 1.".

Additional Information

• 'Fatigue': represents tiredness or exhaustion.
• It would be counterproductive in trying to complete a marathon, not helpful.
• 'Discord': denotes disagreement or strife, and does not have a relevant connection to the physical task of completing a marathon.
• 'Disloyalty': pertains to a lack of faithfulness or loyalty, which is also unrelated to the physical condition required to finish a marathon.

Given:

$\left[{\frac{1}{5} + \left(\frac{9}{15} \times \frac{7}{5} \right) - \left( \frac{4}{5} \times \frac{6}{9}\right) + \frac{3}{4}} \right]$ of $\frac{2}{3}$

Concept used:

Follow the BODMAS rule according to the table given below: 

Calculation:

⇒ $\left[{\frac{1}{5} + \left(\frac{9}{15} \times \frac{7}{5} \right) - \left( \frac{4}{5} \times \frac{6}{9}\right) + \frac{3}{4}} \right]$ of $\frac{2}{3}$

⇒ $\left[{\frac{1}{5} + \left(\frac{21}{25} \right) - \left( \frac{24}{45}\right) + \frac{3}{4}} \right]$of $\frac{2}{3}$

⇒ $\left[{\frac{60 + 252 - 160 + 225}{300}} \right] \times \frac{2}{3}$

⇒ $\left[{\frac{377}{300}} \right] \times \frac{2}{3}$

⇒ $\frac{377}{450}$

∴ $\left[{\frac{1}{5} + \left(\frac{9}{15} × \frac{7}{5} \right) - \left( \frac{4}{5} × \frac{6}{9}\right) + \frac{3}{4}} \right] × \frac{2}{3} = \frac{377}{450}$

The correct answer is Velocity.

CONCEPT:

• Velocity: The rate of change of displacement of a body is called the velocity of that body.
• Velocity is a vector quantity that has both magnitudes as well as direction.
• Acceleration: The rate of change of velocity is called the acceleration of the body.
• Acceleration is also a vector quantity.
• Retardation/Negative acceleration: When the acceleration of the body is in the opposite direction of the velocity is called deceleration.
• It is a negative acceleration of the body.

EXPLANATION:

• The direction of acceleration is determined by the general principle that if an object is slowing down, the acceleration is in the opposite direction of the motion.
• Therefore, from this principle, it becomes clear that when an object is slowing down, the acceleration is in the opposite direction of velocity. This is a negative acceleration. So option 1 is correct.
