Correct Answer: Scientists will have cured AIDS by the year 2070.

Solution : The correct choice is the first option.

Active voice emphasises the doer of the action, while passive voice emphasises the receiver. To convert passive to active, we make the subject perform the action and rephrase the

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: Rs. 10000

Solution : Given,
Difference between compound interest and simple interest = Rs. 25,
Annual interest rate = 10%
We know,
Compound Interest for 1 year = $P[(1 + \frac{r}{100})^n- 1]$, where $r$ is the annual interest rate and $n$ is the number of compounding periods.
Simple

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
