Therefore, the correct answer is, in.
Question : Directions: Select the correct mirror image of the given figure when the mirror is placed at MN as shown below.
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : As per the mirror image properties, closer things appear closer to the mirror in the reflection. Here, according to the information provided, the mirror is placed on the right side of the figure (on line MN). So, the left side of the reflected image will appear

Explanation: Luxurious best fits the context of describing opulent or lavish surroundings, indicating a high level of comfort and wealth. The sentence implies that she lived in surroundings that were well-equipped or affluent, indicating a level of luxury
Question : If $\sin \theta \cos \theta=\frac{1}{\sqrt{3}}$ then the value of $\left(\sin ^4 \theta+\cos ^4 \theta\right)$ is:
Option 1: $1$
Option 2: $\frac{5}{3}$
Option 3: $\frac{2}{3}$
Option 4: $\frac{1}{3}$
Correct Answer: $\frac{1}{3}$
Solution : Given: $\sin \theta \cos \theta=\frac{1}{\sqrt{3}}$ We know that $\sin^2 \theta + \cos^2 \theta = 1$ Squaring both sides, $⇒\sin^4 \theta + \cos^4 \theta + 2\sin^2\theta\cos^2\theta= 1$ $⇒\sin^4 \theta + \cos^4 \theta + 2(\sin\theta\cos\theta)^2 = 1$ $⇒\sin^4 \theta + \cos^4 \theta + 2\times (\frac{1}{\sqrt{3}})^2 = 1$
Question : Directions: Select the set in which the numbers are related in the same way as those of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 - Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed.) (264, 462); (132, 330)
Option 1: (211, 340)
Option 2: (188, 378)
Option 3: (386, 584)
Option 4: (282, 496)
Correct Answer: (386, 584)
Solution : Given: (264, 462); (132, 330)
Like, (264, 462)→264 + 198 = 462 (132, 330)→132 + 198 = 330
Let's check the options – First option: (211, 340)→211 + 198 = 409 ≠ 340 Second option: (188, 378)→188 + 198 = 386 ≠ 378 Third
Question : Directions: Some equations have been solved using the same pattern of a certain system. Find out the correct answer for the unsolved equation using the same pattern. If 4 × 5 × 2 = 524, 3 × 7 × 2 = 723, 6 × 8 × 7 = 876, then, 9 × 4 × 5 = ?
Option 1: 495
Option 2: 459
Option 3: 549
Option 4: 954
Correct Answer: 459
Solution : Given: 4 × 5 × 2 = 524, 3 × 7 × 2 = 723, 6 × 8 × 7 = 876
The first number moves to the third position, the second number moves to the first position, and the third number moves to the
Question : Study the given graph and answer the question that follows.
In how many years was the revenue of the company more than 1.2 times the average expenditure over the given five years?
Option 1: 4
Option 2: 2
Option 3: 1
Option 4: 3
Correct Answer: 2
Solution : According to the question Total expenditure in 2014 to 2018 = 150 + 210 + 350 + 275 + 325 = 1310 ⇒ Average from 2014 to 2018 = $\frac{\text{1310 }}{5}$ = 262 ⇒ 1.2 times of expenditure = 262 × 1.2 = 314.4 In
Question : Two numbers are 90% and 75% less than a third number. By what percentage should the first number be increased so that it becomes equal to the second number?
Option 1: 250
Option 2: 200
Option 3: 150
Option 4: 100
Correct Answer: 150
Solution : Given: Two numbers are 90% and 75% less than a third number. Let the third number be 100. Now, the first and second numbers are 90% and 75% less than the third number. So, the first number = (100 – 100 × $\frac{90}{100}$) = 10
Question : The surface area of a sphere is 221.76 cm2. Its volume (in cm3) is (correct to one decimal place): (Take $\pi=\frac{22}{7}$)
Option 1: 315.6
Option 2: 289.8
Option 3: 280.4
Option 4: 310.5
Correct Answer: 310.5
Solution : The total surface area of the sphere = $4\pi r^2$ Where, $r$ = radius of the sphere According to the question, we have $4\pi r^2 = 221.76$ $⇒4 \times (\frac{22}{7}) \times r^2 = 221.76$ $⇒ r^2 = 17.64$ $\therefore r = 4.2\ \text{cm}$ Now, The
Question : Reverse transcription was discovered by:
Option 1: Beadle & Tatum
Option 2: Waston & Crick
Option 3: Temin & Baltimore
Option 4: har Govind Khorana
Correct Answer: Temin & Baltimore
Solution : The correct option is - Temin & Baltimore.
David Baltimore and Howard Temin independently and concurrently discovered reverse transcriptase in retroviruses (at the time, RNA tumor viruses), which revolutionized molecular biology and laid the groundwork for retrovirology and cancer biology in 1970.
