Correct Answer: surrender

Solution : The correct choice is the fourth option.

Explanation: When considering the meaning of prevail, which implies overcoming, succeeding, or winning, the antonym should convey the idea of yielding, giving up, or admitting defeat. Surrender fits this context, as it signifies the act of yielding or conceding in the face of opposition.
The meanings of the other options are as follows:

• Succeed: This word means to achieve success, accomplish a goal, or attain a desired outcome.
• Prove: This word refers to demonstrating the truth or validity of something.
• Control: This word means to manage, direct, or regulate a situation or entity.

Therefore, the correct antonym is surrender.

Correct Answer: getting on

Solution : The most appropriate option to substitute is the first option.

Explanation: The original sentence uses the preposition "going on" which may cause confusion. The phrasal verb "getting on" is more suitable in this context, as it is commonly used to inquire about the progress or status of someone's work or tasks. "Getting on" implies movement or advancement, making it an appropriate choice when asking about how someone is managing or progressing with his work.

So, the correct sentence would be: "How are you getting on with your work?"

Correct Answer: I said that I had taken a lot of precautions after my surgery.

Solution : The correct choice is the second option.

Indirect speech, also known as reported speech or indirect discourse, is a way of reporting what someone else has said without quoting their exact words.

The steps of construction are as follows:

• There would be no change in the reporting verb of the indirect speech.
• The simple past tense "took" is changed to the past perfect tense "had taken".
• The connector "that" is used to introduce the reported clause.

Therefore, the correct answer is: "I said that I had taken a lot of precautions after my surgery."

Solution : Since there is a restriction on the rotation of the figure, we will check which of the option figures can exactly fit in the given question figure.
By comparison of all the option figures, only the second option figure is embedded in the given question figure.

Hence, the second option is correct.

Correct Answer: 8

Solution : In a column, multiply the first number by the second number and then the third number to get the fourth number.

In the first column: 6 × 7 × 11 = 462
In the second column: 5 × 8 × 12 = 480
Similarly, follow the same pattern in the third column: 7 × 4 × ? = 224
⇒ 28 × ? = 224
⇒ ? = 224 ÷ 28 = 8

So, 8 is the missing number in the given figure. Hence, the second option is correct.

Correct Answer: The Northeast monsoons pick up moisture from the Bay of Bengal and these winds are obstructed by the Eastern Ghats.

Solution : The correct answer is The Northeast monsoons pick up moisture from the Bay of Bengal and these winds are obstructed by the Eastern Ghats.

Correct Answer: QJRGU

Solution : Given:
CAMEL is coded as CEMNG and TIGER is coded as KVGTG.

Add 2 to the place value of the first two and last two letters of CAMEL and TIGER, then interchange their positions. The middle letter remains constant.

Thus, CAMEL is coded as CEMNG.

Thus, TIGER is coded as KVGTG.
Similarly, follow the same pattern for HORSE –

Thus, HORSE is coded as QJRGU. Hence, the fourth option is correct.

Correct Answer: 104

Solution : Given:
15 12 81
17 14 93
15 11 ?

Solve according to rows, in each row the sum of the first and the second numbers is multiplied by the result of the subtraction of the second number from the first number to obtain the third number.
First row: (15 + 12) × (15 – 12)  = 27 × 3 = 81
Second row: (17 + 14) × (17 – 14) = 31 × 3 = 93
Similarly, Third row: (15 + 11) × (15 – 11) = 26 × 4 = 104

So, the required number is 104. Hence, the first option is correct.
