Correct Answer: Periscope 

Solution : Given:
Star : Telescope :: Ship : ? 

A telescope is a device used to magnify and observe distant stars.

Correct Answer: 48.07%

Solution : Imports in 1976 = 2700 (in thousand tonnes)
Imports in 1975 = 5200 (in thousand tonnes)
The decrease in imports in 1976 = 2500 (in thousand tonnes)
$\therefore$ The decrease percentage = $\frac{2500}{5200}\times{100}$ = 48.07%
Hence, the correct answer is 48.07%.

Correct Answer: 7

Solution : Given: $\sin^2\theta + \cos^2\theta+\sec^2\theta+\operatorname{cosec}^2\theta+\tan^2\theta+\cot^2\theta$
= $(1+\sec^2\theta+\operatorname{cosec}^2\theta+\tan^2\theta+\cot^2\theta)$
= $(1+1+\tan^2\theta+1+\cot^2\theta+\tan^2\theta+\cot^2\theta)$
= $(3+2\tan^2\theta+2\cot^2\theta)$
= $3+2(\tan^2\theta+\cot^2\theta)$
The value of the above expression is minimum when $\tan^2\theta+\cot^2\theta$ is minimum.
We know that $\tan^2\theta+\cot^2\theta \geq 2$
So, the minimum value is [3 + (2 × 2)] = 7
Hence, the correct

Correct Answer: Solitory
