Question : If A's wealth is $\frac{4}{9}$ times of B's and C's is $\frac{7}{6}$ times of B's. What is the ratio of C's wealth to A's?
Option 1: 8:21
Option 2: 21:8
Option 3: 27:14
Option 4: 14:27
Correct Answer: 21:8
Solution : Given: A's wealth is $\frac{4}{9}$ times of B. C's wealth is $\frac{7}{6}$ times of B. ⇒ A's wealth = B's wealth × $\frac{4}{9}$ ⇒ C's wealth = B's wealth × $\frac{7}{6}$ Ratio of C's wealth to A's wealth = $\frac{\frac{7}{6}}{\frac{4}{9}}$ $⇒\frac{21}{8}$ ⇒ 21:8 Therefore, option
Question : PQRS is a cyclic quadrilateral. If $\angle$P is three times of $\angle$R and $\angle$S is four times of $\angle$Q, then the sum of $\angle$S + $\angle$R will be:
Option 1: $169^{\circ}$
Option 2: $171^{\circ}$
Option 3: $187^{\circ}$
Option 4: $189^{\circ}$
Correct Answer: $189^{\circ}$
Solution : $\angle$P = 3$\angle$R $\angle$S = 4$\angle$Q As PQRS is a cyclic quadrilateral, $\angle$P + $\angle$R = $180^{\circ}$ ⇒ 3$\angle$R + $\angle$R = $180^{\circ}$ ⇒ 4$\angle$R = $180^{\circ}$ $\therefore$ $\angle$R = $45^{\circ}$ ⇒ $\angle$P = 3 × $45^{\circ}$ = $135^{\circ}$ $\angle$S + $\angle$Q = $180^{\circ}$ ⇒
Question : Comprehension: In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank.

Solution : The correct answer is in the third option.
The context suggests that people are left to mourn the harsh realities after their loved ones are gone. Mourn is the suitable word here, as it means to feel or express grief or sorrow, especially in response
Question : If $a \cot \theta+b \operatorname{cosec} \theta=p$ and $b \cot \theta+a \operatorname{cosec} \theta=q$ then $p^2-q^2$ is equal to.
Option 1: $a^2+b^2$
Option 2: $a^2-b^2$
Option 3: $b^2-a^2$
Option 4: $b-a$
Correct Answer: $b^2-a^2$
Solution : Given: $a \cot \theta+b \operatorname{cosec} \theta=p$ Squaring both sides, We get $(a \cot \theta+b \operatorname{cosec} \theta)^{2} =p^{2}$ ⇒ $a^{2} \cot^{2}\theta+b^{2} \operatorname{cosec}^{2}\theta +2ab \cot \theta\operatorname{cosec} \theta =p^{2}$……(i) And $b \cot \theta+a \operatorname{cosec} \theta=q$ Squaring both sides, We get $(b \cot \theta+a \operatorname{cosec} \theta)^{2}=q^2$ ⇒ $b^2 \cot^{2}\theta+a^2

Question : Directions: In the following question, some parts of the sentence have errors, and some are correct. Find out which part of the sentence has an error. The number of that part is the answer. If a sentence is error-free, your answer is "No error".
He'd no sooner (1) / seen one continent (2) /when he saw another. (3) / No error (4)
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4
Correct Answer: 3
Solution : The error lies in the third part of the sentence.
Explanation: The correlative conjunction "no sooner...than" is used to indicate that one action or event happens immediately after another. In this case, "than" should be used after he'd no sooner seen one continent, which correctly
Question : Directions: Select the option in which the following figure is embedded (Rotation is NOT allowed).
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : Since there is a restriction on the rotation of the figure, we will check where the question figure can exactly fit itself in the given option figures. By comparison of all the option figures, the given question figure is embedded only in the fourth option figure.
Question : The table given below shows the income of two companies C1 and C2 in 6 years.
Which of the following statements is NOT correct? I. The income of C1 in year P is 33.33% of the income of C2 in year Q. II. The average income of C1 and C2 in year T is 400.
Option 1: Only I
Option 2: Both I and II
Option 3: Neither I nor II
Option 4: Only II
Correct Answer: Only I
Solution : The income of C1 in year P is 750 and the income of C2 in year Q is 250. So, the income of C1 in year P is $\frac{750}{250}×100$ = 300% of the income of C2 in year Q. Therefore, the first statement is
