Correct Answer: 33

Solution : Given: $(2000)^{10} = 1.024×10^{k}$
⇒ $(2×1000)^{10} = \frac{1024}{1000}×10^{k}$
⇒ $2^{10}×10^{30} = 2^{10}×10^{k–3}$
⇒ $10^{30} =10^{k-3}$
By comparing the powers, we get:
$(k-3) = 30$
$\therefore k = 33$
Hence, the correct answer is 33.

Correct Answer: $\frac{3}{5}$

Solution :

$\tan \theta=\frac{8}{15}=\frac{\text{Perpendicular}}{\text{Base}}$
$\therefore$ Hypotenuse = $\sqrt{8^2+15^2}=\sqrt{289}= 17$
So, $\sin \theta=\frac{8}{17}$
$\sqrt{\frac{1-\sin \theta}{1+\sin \theta}}=\sqrt{\frac{1-\frac{8}{17}}{1+\frac{8}{17}}}=\sqrt{\frac{\frac{9}{17}}{\frac{25}{17}}}=\sqrt{\frac{9}{25}}=\frac{3}{5}$
Hence, the correct answer is $\frac{3}{5}$.

Correct Answer: 500

Solution : Given: 60% of A = 30% of B, B = 40% of C, and C = $x$% of A
Here, C = $x$% of A ⇒ C = $\frac{x×A}{100}$
and B = 40% of C ⇒ B = $\frac{40×C}{100}$ ⇒ B = $\frac{40×x×A}{100×100}$ = $\frac{2×x×A}{500}$
