Correct Answer: $\frac{12}{5}$

Solution : Given: $\sec\theta+\tan\theta=5$--------------------(equation 1)
We know,
$\sec^2\theta-\tan^2\theta=1$
⇒ $(\sec\theta+\tan\theta)(\sec\theta-\tan\theta)=1$
⇒ $(5)(\sec\theta-\tan\theta)=1$
⇒ $(\sec\theta-\tan\theta)=\frac{1}{5}$----------------------(equation 2)
Now, solving equations 1 and 2 we get,
$\tan\theta=\frac{12}{5}$
Hence, the correct answer is $\frac{12}{5}$.

Correct Answer: 1.33

Solution : Import during 2017-18 = 1600
Import during 2016-17 = 1200

Solution : According to the question,
$c^2 = ab$
where $c$ is the mean proportion of $a$ and $b$.
Now, the mean proportion of 12.8 and 64.8
 $x=\sqrt{12.8 \times 64.8}$
 $=\sqrt{16 \times 0.8\times 0.8 \times 81}$
 $=4 \times 0.8 \times 9$
$x=28.8$
Hence, the correct answer is
