Correct Answer: 20 metres

Solution : Given: The perimeter of the top of a rectangular table is 56 metres and its area is 192 m².
Use the formulas,
Perimeter = $2(l+b)$
Area = $l\times b$
Length of diagonal = $\sqrt{l^2+b^2}$
Where $l$ and $b$ are length and breadth.
Here, $2(l+b)=56$
⇒ $(l+b)=28$
Also, $lb=192$.
We know the identity, $a^2+b^2=(a+b)^2-2ab$.
⇒ $l^2+b^2=(l+b)^2-2lb$
Substitute the values in the above equation,
⇒ $l^2+b^2=(28)^2–2\times 192$
⇒ $l^2+b^2=784–384=400$
The length of its diagonal = $\sqrt{l^2+b^2}$ = $\sqrt{400}$ = 20 m.
Hence, the correct answer is 20 metres.

Correct Answer: salary of their living

Solution : The correct choice is the third option.

Explanation: In the phrase "salary of their living" the error is with the use of "of" instead of "for". The correct preposition "for" should be used to indicate the purpose for which the salary is used.

Therefore, the correct sentence would be: Both of my parents are dependent on my salary for their living.

Correct Answer: 113

Solution : Given:
× means –; – means ×; + means ÷ and ÷ means +.
(15 – 10) ÷ (130 + 10) × 50 = ?

After replacing the symbols, the equation becomes –
= (15 × 10) + (130 ÷ 10) – 50
= 150 + 13 – 50
= 163 – 50
= 113

So, 113 is the answer to the given equation. Hence, the second option is correct.

Correct Answer: 5 hours 20 minutes

Solution : Time taken by A₁ to do the work = 12 hours
⇒ 1 day's work of A₁ = $\frac{1}{12}$
Time taken by A₂ to do the work = 24 hours
⇒ 1 day's work of A₂ = $\frac{1}{24}$
Time taken by A₃ to do the work = 16 hours
⇒ 1 day's work of A₃ = $\frac{1}{16}$
If A₁, A₂, and A₃ work together, work will be done in a day
= $\frac{1}{12}$ + $\frac{1}{24}$ + $\frac{1}{16}$
= $\frac{4+2+3}{48}$
= $\frac{9}{48}$
= $\frac{3}{16}$
So, Time taken by A₁, A₂, and A₃ together to do the work
= $\frac{16}{3}$
= $5\frac{1}{3}$ hours
= 5 hours 20 minutes
Hence, the correct answer is 5 hours 20 minutes.

Correct Answer: Archery

Bombayla Devi Laishram is a female archer from India. She has been part of India's national recurve squad since 2007. She has been awarded with Padma Shri and Arjuna awards for her performance. She also won four gold, five silver and four bronze medals at various editions of the Archery World Cup.

Correct Answer: Only II

Solution : The correct solution is Only II.

Afforestation has the purpose of restoring an area that has been destroyed due to previous overuse of the land. It helps in the reduction of soil erosion. Carbon dioxide (CO₂) traps heat and does not allow it to escape into the air. It is a greenhouse gas. Greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range.

Correct Answer: Inaudible

Solution : The correct choice is the first option.

The word inaudible refers to a sound that is not able to be heard. In this context, it serves as a single word that succinctly captures the meaning of "a sound that cannot be heard".

The meanings of the other words are as follows:

• Audacious: This word describes someone bold, daring, or fearless.
• Autonomous: This term refers to something that operates independently or can function without external control.
• Delible: This word pertains to something that can be erased, blotted out, or easily removed.

Therefore, the most appropriate one-word substitute is inaudible.
