Question : Directions: In this question, three statements are given, followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follows/follow from the statements. Statements: All pens are books. All books are novels. All novels are good. Conclusions: I. Some novels are pens. II. All books are good.

Solution : The possible Venn diagram, according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): Some novels are pens – From the Venn diagram, it is evident that some parts of the circle representing novels
Question : In the adjoining figure $\angle AOC=140^{\circ}$, where O is the centre of the circle then $\angle ABC$ is equal to:
Option 1: $110^{\circ}$
Option 2: $100^{\circ}$
Option 3: $90^{\circ}$
Option 4: $40^{\circ}$
Correct Answer: $110^{\circ}$
Solution : Given: $\angle AOC = 140^{\circ}$ Construction: Take D on the remaining arc. We know that, The angle formed by the chord at the centre is twice the angle formed in the same arc segment. $\angle AOC = 2\angle ADC$ ⇒ $140^{\circ} = 2\angle ADC$ $\therefore
Question : Which of the following is not a part of the Peninsular Plateau?
Option 1: The Deccan Plateau
Option 2: The Central Highland
Option 3: The Northern Plain
Option 4: The North-eastern Plateau
Correct Answer: The Northern Plain
Solution : The correct option is the Northern Plain.
The Northern Plain is distinct from the Peninsular Plateau due to its northern location, younger formation from river deposits, and flatter, fertile terrain. While the Deccan Plateau, Central Highland, and North-Eastern Plateau are part of
Question : Directions: Choose a similar group of numbers based on certain common properties they possess. (72, 66, 96)
Option 1: (54, 57, 78)
Option 2: (24, 69, 58)
Option 3: (55, 66, 77)
Option 4: (63, 70, 86)
Correct Answer: (55, 66, 77)
Solution : Given: (72, 66, 96)→72 ÷ 12 = 6, 66 ÷ 11 = 6, 96 ÷ 16 = 6. Here, all the numbers are multiples of 6.
Let's check the options – First option: (54, 57, 78); 54 ÷ 9 = 6, 78 ÷

Option 3: FHDJB
Option 4: WYUAS
Correct Answer: TVRXQ
Solution : Let's check the options –
First option: NPLRJ; N + 2 = P; P – 4 = L; L + 6 = R; R – 8 = J Second option: TVRXQ; T + 2 = V; V – 4 = R; R + 6 =
Question : In a right-angled triangle for an acute angle $x$, find $\sin x$. It is given that $\tan x = 5$.
Option 1: $\frac{1}{3}$
Option 2: $\frac{5}{\sqrt{26}}$
Option 3: $\frac{2}{5}$
Option 4: $\frac{5}{\sqrt{28}}$
Correct Answer: $\frac{5}{\sqrt{26}}$
Solution : Given, $\tan x = 5$ We know that, $\tan x=\frac{\text{Perpendicular}}{\text{Base}}=\frac{5}{1}$ Let the perpendicular($p$) and base($b$) be 5 units and 1 unit. Let the hypotenuse be $h$. Using the Pythagoras theorem, $h^2=p^2+b^2$ ⇒ $h^2=5^2+1^2$ ⇒ $h=\sqrt{26}$ units So, $\sin x =\frac{\text{Perpendicular}}{\text{Hypotenuse}}= \frac{5}{\sqrt{26}}$ Hence, the correct answer
