Question : Directions: Select the related letter cluster from the given alternatives. ZXVT : YWUS :: RPNL : ?
Option 1: XVTS
Option 2: TSQP
Option 3: SQPM
Option 4: QOMK
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.
Question : Direction: In each of the following question, select the missing number from the given responses.
Option 1: 15
Option 2: 5
Option 3: 6
Option 4: 3
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.
Question : In the given figure, PAB is a secant and PT is a tangent to the circle from P. If PT = 8 cm, PA = 6 cm, and AB = $x$ cm, then the value of $x$ is:
Option 1: $\frac{14}{9}$
Option 2: $\frac{1}{3}$
Option 3: $\frac{14}{3}$
Option 4: $\frac{4}{3}$
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 $\frac{14}{3}$.
Question : In Tennis, what is the score when the receiver wins the next point after deuce?
Option 1: Advantage out
Option 2: 30-40
Option 3: Advantage in
Option 4: 40-30
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.
Question : Select the option that expresses the given sentence in passive voice.
The ruler of the community had already passed a decree against that decision.
Option 1: A decree had already passed by the ruler of the community against that decision.
Option 2: A decree was already passed by the ruler of the community against that decision.
Option 3: A decree was already being passed by the ruler of the community against that decision.
Option 4: A decree had already been passed by the ruler of the community against that decision.
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."
Question : Directions: In the following question, select the missing number from the given series. 123, 125, 127, ?, 131, 133
Option 1: 128
Option 2: 129
Option 3: 130
Option 4: 145
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.

Question : Salaries of B, C, D, and E are in the ratio of 2 : 3 : 4 : 5 respectively. Their salaries are increased by 20%, 30%, 40% and 50% respectively. If the increased salary of D is INR 560, then what is the sum of the original salaries of B, C, D, and E?
Option 1: INR 1,400
Option 2: INR 1,560
Option 3: INR 1,820
Option 4: INR 1,260
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.
