Question : Directions: In the given figure, how many huts are covered and muddy?
Option 1: 28
Option 2: 40
Option 3: 33
Option 4: 19
Correct Answer: 19

Question : Direction: G is fatter than H but not as fat as M. Q is also not as fat as M. Who is the leanest person in the group?
Option 1: Q
Option 2: H
Option 3: G
Option 4: Cannot be determined
Correct Answer: Cannot be determined
Solution : Given:
G is fatter than H but not as fat as M → M > G > H
Q is also not as fat as M → M > Q
So, from the above, it's not clear whether Q is the leanest or
Question : Select the most appropriate synonym of the highlighted word in the given sentence. A strong man is a mediator between divine and mortal fate.

Question : Direction: In the following question, select the one that is different from other three alternatives.
Option 1: 240
Option 2: 304
Option 3: 272
Option 4: 210
Correct Answer: 240
Solution : Let's check the options —
First option: 240 Add the digits → 2 + 4 + 0 = 6; 6 is not a prime number → Hence, it's the odd one out.
Second option: 304 Add the digits → 3 + 0 + 4 =
Question : The value of $\frac{\sin A}{1+\cos A}+\frac{\sin A}{1-\cos A}$ is $(0°<A<90°)$:
Option 1: $2\operatorname{cosec}A$
Option 2: $2 \sec A$
Option 3: $2 \sin A$
Option 4: $2 \cos A$
Correct Answer: $2\operatorname{cosec}A$
Solution : Given: $\frac{\sin A}{1+ \cos A}+\frac{\sin A}{1- \cos A}$ = $\frac{\sin A(1–\cos A)+\sin A (1+\cos A)}{(1+ \cos A)(1- \cos A)}$ = $\frac{\sin A–\sin A \cos A+\sin A+\sin A \cos A}{(1- \cos^{2} A)}$ = $\frac{2\sin A}{\sin^{2}A}$ = $\frac{2}{\sin A}$ = $2 \operatorname{cosec}A$ Hence, the correct answer is
Question : Select the most appropriate option that can substitute the underlined segment in the given sentence. If there is no need to substitute it, select 'No substitution required'. Have you want me to come with you to the dentist?
Option 1: Has you wanted me
Option 2: No substitution required
Option 3: Had you want me
Option 4: Do you want me
Correct Answer: Do you want me
Explanation: The correct form should be: "Do you want me to come with you to the dentist?"
The auxiliary verb "do" is needed before the subject to form an interrogative sentence in the
Question : The average of the first three numbers is double the fourth number. If the average of all the four numbers is 12. Find the 4th number.
Option 1: $16$
Option 2: $\frac{48}{7}$
Option 3: $20$
Option 4: $\frac{18}{7}$
Correct Answer: $\frac{48}{7}$
Solution : Let the four numbers be $p, q, r$ and $s$. $⇒\frac{p+q+ r+s}{4}=12$ $⇒p+q+r+s=48$ ...(i) $⇒\frac{p+q+r}{3}=2s$ $⇒p+q+r=6s$ ...(ii) Putting equation (ii) in equation (i), we get, $⇒6s+s=48$ $⇒7s=48$ $\therefore s=\frac{48}{7}$ Hence, the correct answer is $\frac{48}{7}$.
Question : Directions: Three different positions of the same dice are shown. Find the number on the face opposite the face showing 2.
Option 1: 1
Option 2: 6
Option 3: 3
Option 4: 4
Correct Answer: 1
Solution : Taking dice positions 1 and 2 with 2 as common face,
Moving clockwise from the common face with 2,
Pairs of opposite faces –
So, the opposite face to the face containing 2 is 1. Hence, the first option is correct.
Question : In the given figure, the radius of a circle is $14\sqrt{2}$ cm. PQRS is a square. EFGH, ABCD, WXYZ, and LMNO are four identical squares. What is the total area (in cm2) of all the small squares?
Option 1: 31.36
Option 2: 125.44
Option 3: 62.72
Option 4: 156.8
Correct Answer: 125.44
Solution :
Given that the radius of the circle = $14\sqrt{2}$ cm The diameter of the circle = $2 \times 14\sqrt{2} = 28\sqrt{2}$ cm. The side of the larger square (PQRS) = $\frac{\operatorname{diameter}}{\sqrt2}=28$ cm. TO = half the side of the larger square = $14$ cm. The
