Correct Answer: QOMK

Solution : Given:
ZXVT : YWUS :: RPNL : ?

Like, ZXVT→Z – 1 = Y; X – 1 = W; V – 1 = U; T – 1 = S
Thus, ZXVT is related to YWUS.
Similarly, follow the same pattern for RPNL –
R – 1 = Q; P – 1 = O; N – 1 = M; L – 1 = K

Thus, RPNL is related to QOMK. Hence, the fourth option is correct.

Correct Answer: 15

Solution : Given: 

In the first column, 8 – 6 = 2 → 2 + 2 = 4

In the second column, 12 – 5 = 7 → 7 + 8 = 15

In the third column, 13 – 10 = 3 → 18 – 3 = 15

So, the missing number is 15.

Hence, first option is correct.

Correct Answer: $\frac{14}{3}$

Solution :
As we know,
PT² = PA × PB
⇒ 8² = 6($x$ + 6)
⇒ 64 = 6$x$ + 36
⇒ $x$ = $\frac{28}{6} = \frac{14}{3}$
Hence, the correct answer is $\frac{14}{3}$.

Correct Answer: Advantage out

Solution : The correct option is Advantage Out.

When the score is tied, the next point won by a player is referred to as an "advantage." If the receiver wins the next point after a deuce, the score becomes "advantage [receiver's name]". If the receiver wins the next point, they win the game.

Correct Answer: A decree had already been passed by the ruler of the community against that decision.

Solution : The fourth option is the correct choice.

Passive voice is the voice in which the object experiences an action rather than the person who performs the action. Hence, the object in the active sentence becomes the subject in the passive voice.

The structure of the passive voice in the case of the past perfect tense is: "Singular object + had + been + past participle form of the verb + 'by' followed by the agent of the action."

Therefore, the correct sentence is: "A decree had already been passed by the ruler of the community against that decision."

Correct Answer: 129

Solution : Given:
123, 125, 127, ?, 131, 133

Add 2 to the previous term to get the next term.
123 + 2 = 125; 125 + 2 = 127; 127 + 2 = 129; 129 + 2 = 131; 131 + 2 = 133

So, 129 is the missing term in the series. Hence, the second option is correct.

Correct Answer: entails

Solution : The fourth option is the correct answer.

The word entails fits well in the context of the sentence. The sentence discusses the meaning of being constant and entails means to involve or necessitate as a consequence. It makes sense in the sentence, conveying that being constant involves repeating a task or action.

The meanings of the other options are as follows:

• Envelops means to surround or enclose.
• Initiates means starts or begins.
• A figure refers to a number or shape.

Correct Answer: INR 1,400

Solution : Given: Salaries of B, C, D, and E are in the ratio of 2 : 3 : 4 : 5 respectively.
Percentage increase = 20%, 30%, 40%, and 50%.
Let the salary of B, C, D, and E be $2x, 3x, 4x,$ and $5x$, respectively.
According to the question,
$4x+0.4(4x)=560$
⇒ $4x+1.6x=560$
⇒ $5.6x=560$
⇒ $x=100$
The sum of the original salaries of B, C, D, and E
$=2x+3x+4x+5x=14x=14\times100=$ INR 1,400
Hence, the correct answer is INR 1,400.

Correct Answer: Rhodophyceae

Solution : The correct answer is Rhodophyceae.

The Rhodophyceae division is the taxonomic classification for these red algae. They are distinguished by their reddish or purple hue, attributed to pigments like phycoerythrin and phycocyanin.

Correct Answer: 71

Solution : Let's check the options –
First option: 42; 42 is divisible by 1, 2, 3, 6, 7, 14, 21, 42. It is not a prime number.
Second option: 84; 84 is divisible by 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84. It is not a prime number.
Third option: 91; 91 is divisible by 1, 7, 13, 91. It is not a prime number.
Fourth option: 71; 71 is divisible by only 1 and 71. It is a prime number. 

The fourth option does not follow a similar pattern as the other options. Hence, the fourth option is correct.
