Correct Answer: 85

Solution : Virat Kohli's batting average = $\frac{\text{Runs}}{\text{Inning – Not out}}$ = $\frac{752}{12-3}$ = 83.66
Also, batting average of Gautam Gambhir = 44.9
So, the required percentage = $\frac{\text{Difference in batting average}}{\text{Batting average of Gautam Gambhir}}×100$
= $\frac{83.66-44.9}{44.9}×100$
= $\frac{38.37}{44.9}×100$
= 85.45% (approx)
Hence, the correct answer is 85.

Correct Answer: Neither conclusion I nor II follows

Solution : According to the given statement –
Conclusion I: Singers make a song.
This conclusion does not necessarily follow from the given statement. The statement mentions that songs have singers to sing them, which implies a relationship between singers and songs, but it does not explicitly state that singers make the song itself. A song can be created by songwriters, composers, or musicians, and singers may interpret or perform those songs.
Conclusion II: There is no un-sung song.
This conclusion is not directly addressed in the given statement. The statement indicates that songs have singers to sing them, but it does not make any claims about the existence or absence of un-sung songs. The statement is focused on the role of singers in singing songs, not on the status of un-sung songs.

So, neither conclusion I nor conclusion II follows. Hence, the third option is correct.

Correct Answer: 96

Solution : 2505 + $x$ = perfect square
The perfect square nearest to 2505 is 2601 = 51²
$\therefore x$ = 2601 – 2505 = 96
Hence, the correct answer is 96. 

Correct Answer: 10

Solution : Given: (0.1 × 0.01 × 0.001 × 10⁷)
= 0.1 × 0.01 × 0.001 × 10⁷
= 10^–1 × 10^–2 × 10^–3 × 10⁷
= 10^–6 × 10⁷ 
= 10
Hence, the correct answer is 10.

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.

Hence, the fourth option is correct.

Correct Answer:

Solution : Since there is a restriction on the rotation of the figure, we will check which of the option figures can exactly fit in the given question figure.
By comparison of all the option figures, only the first option figure is embedded in the given question figure.

Hence, the first option is correct.

Correct Answer: 84

Solution : The LCM and ratio of the three numbers = 1386
Let the numbers be $3x, 7x,$ and $11x$.
According to the question:
$(3\times7\times11)x=1386$
⇒ $231x=1386$
$\therefore x=6$
Thus, Least number $= 3x=3\times6=18$
Greatest number $=11x=11\times6=66$
$\therefore$ Sum $=18+66=84$
Hence, the correct answer is 84.

Correct Answer: Snake

Solution : The correct option is Snake

Snakes are cold-blooded (ectothermic) which means they cannot control their body temperature. They depend on outside heat sources like the sun or warm surfaces, to maintain their activity and metabolism. They can survive in a range of environments and conserve energy due to their versatile nature.
