Question : Which of the following laws, represented by the formula T2/R3, compares the orbital period and radius of the orbit of a planet with that of other planets?
Option 1: Hubble's Law
Option 2: Copernicus's Law
Option 3: Kepler's Third Law
Option 4: Bragg's Law
Correct Answer: Kepler's Third Law

It states that the square of the orbital period (T) of a planet is directly proportional to
Question : Anuj's efficiency is 150 percent of Vinod's efficiency. If Anuj can complete a work in 20 days, then how many days will they together take to complete the same work?
Option 1: 6 days
Option 2: 9 days
Option 3: 15 days
Option 4: 12 days
Correct Answer: 12 days
Solution : Let Vinod's efficiency be $x$ Let the total time taken by them to complete the work = $t$ days Anuj's efficiency = $\frac{3}{2}x$ Number of days taken by Anuj to complete the work = 20 days Total work = Efficiency × Time Now, $20\times

Question : The sentences of a paragraph are given below. While the first and the last sentences (S1 and S6) are in the correct order, the sentences in between are jumbled up. Arrange the sentences in the correct order to form a meaningful and coherent paragraph.
S1. He sat in his seat A. hardly showing any signs of hearing B. beside the bed, C. gazing sternly D. at the patient’s face S6. what they were saying to him.
Option 1: DABC
Option 2: BCDA

Correct Answer: BCDA
Solution : The correct choice is the second option: BCDA.
The logic behind the rearrangement is to first establish the setting followed by describing the character's action, and then specifying the target of his gaze. Next, we observe the patient's behaviour before concluding with the context
Question : From point P on the level ground, the angle of elevation to the top of the tower is 30°. If the tower is 100 metres high, the distance of point P from the foot of the tower is: (Take $\sqrt{3}$ = 1.73)
Option 1: 149 m
Option 2: 156 m
Option 3: 173 m
Option 4: 188 m
Correct Answer: 173 m
Solution : Let AB be the tower. Given: AB = 100 m and $\theta$ = 30° In $\triangle$ PAB, $\tan$ $\theta$ = $\frac{AB}{PB}$ ⇒ $\tan 30°$ = $\frac{100}{PB}$ ⇒ $\frac{1}{\sqrt{3}}$ = $\frac{100}{PB}$ ⇒ $PB = 100 × \sqrt{3} = 100 × 1.73 = 173$ m Hence,
Question : Directions: P, Q, R, S, T, and U are six friends sitting at equal distances from each other around a circular table facing the center of the table.

Option 1: S
Option 2: P
Option 3: R
Option 4: Q
Correct Answer: P
Solution : Given: I. U is sitting at the 4th position to the left of T.
II. Someone is sitting between S and T but it's not P. R is sitting to the immediate left of U.
Therefore, P is sitting opposite T. Hence, the second option
