Correct Answer: 27.58

Solution :
AB = Height of observer = 1.6 m.
CD = Height of tower = $h$ m.
∴ DE = ($h$ – 1.6) m
BC = AE = 45 metres
$\angle$DAE = 30°
From $\triangle$DAE,
$\tan 30°=\frac{DE}{AE}$
⇒ $\frac{1}{\sqrt{3}}=\frac{h-1.6}{45}$
⇒ $h-1.6=15\sqrt{3}$
⇒ $h – 1.6 =

Correct Answer: 2

Solution : We know that $\sin \theta = \cos (90°-\theta)$
And, $\tan \theta = \cot (90°-\theta)$
So, $\cos ^2 35^{\circ}+\cos 55^{\circ} \cdot \sin 35^{\circ}+\frac{\tan 34^{\circ}}{\cot 56^{\circ}}$
= $\cos ^2 35^{\circ}+\cos (90^{\circ}-35^{\circ}) \cdot\sin 35^{\circ}+\frac{\tan(90^{\circ}- 56^{\circ})}{\cot 56^{\circ}}$
= $\cos ^2 35^{\circ}+\sin 35^{\circ} \cdot \sin 35^{\circ}+\frac{\cot 56^{\circ}}{\cot 56^{\circ}}$
= $\cos

Correct Answer: 15 : 38

Solution : Here, the LCM of the denominators of all the options is 38.
So, $\frac{8}{19} = \frac{8×2}{19\times 2}=\frac{16}{38}$
$ \frac{15}{38} $, $ \frac{17}{38}$
$ \frac{13}{19}= \frac{13×2}{19\times 2}=\frac{26}{38}$
$\therefore$ 15 : 38 is the lowest ratio.
Hence, the correct answer is 15 : 38.

Correct Answer: + and –

Solution : Given:
6 + 8 ÷ 4 – 4 = 8 

Let's check the options –
First option: ÷ and =
6 + 8 = 4 – 4 ÷ 8
LHS→6 + 8 = 14
RHS→4 – 4 ÷ 8
= 4 – 0.5

Correct Answer: 5.25 cm

Solution : Given: Surface area of a sphere = 346.5 cm²
Let the radius of the sphere be $r$.
We know, the surface area of a sphere $= 4\pi r^2$
⇒ $346.5 = 4\pi r^2$
⇒ $r^2$ = $\frac{346.5×7}{4×22}$
⇒ $r^2= 27.5625$
$\therefore r =
