Correct Answer: 8:45

Solution : Given:
Reflected time is 3:15.

Because the time 3:15 lies between 1:00 and 11:00, so to get the actual time subtract the reflected time from 11:60.
Actual time = 11:60 – 3:15 = 8:45

So, 8:45 is the right time. Hence, the first option is

Correct Answer: $55^\circ$

Solution :
Given: $\angle A = 70^\circ$
To find: $\angle BOC$
We know that,
Angle formed by external angle bisectors = $90^\circ-\frac{1}{2}\angle A$
⇒ $\angle BOC$ = $90^\circ-\frac{1}{2}\angle A$
= $90^\circ-\frac{1}{2}×70^\circ$
= $90^\circ-35^\circ$
= $55^\circ$
Hence, the correct answer is $55^\circ$.

Correct Answer: 4 and 64

Solution : Let the two numbers as $a$ and $b$. The mean proportion of two numbers is the square root of their product. 
$\sqrt{ab} = 16$
Squaring both sides, 
$ab = 256$.....................................(1)
The third proportional of two numbers $a$ and $b$ is the number which

Correct Answer: $3 \frac{384}{529}$

Solution : Given:
$\sec \theta=2 \frac{4}{23}=\frac{50}{23}$
We know, $\tan^2\theta=\sec^2\theta-1$
⇒ $\tan^2\theta=(\frac{50}{23})^2-1$
⇒ $\tan^2\theta=\frac{2500}{529}-1$
⇒ $\tan^2\theta=\frac{1971}{529}$
$\therefore \tan^2\theta=3 \frac{384}{529}$
Hence, the correct answer is $3 \frac{384}{529}$.

Correct Answer: satisfy human wants

Solution : The correct answer is to satisfy human wants.

The fundamental goal of all manufacturing is to generate commodities and services that fulfil human desires and needs. To put it another way, the primary goal of production is to create items that may

Correct Answer: Tariffs and quotas

Solution : The correct option is Tariffs and quotas.

Both tariffs and quotas are consistent with import substitution policies. Import substitution is an economic policy that aims to promote domestic industries by reducing reliance on imported goods. Tariffs involve imposing taxes on imported goods,

Correct Answer: 7

Solution : Given: The sum of a non-zero number and thrice its reciprocal is $\frac{52}{7}$.
Let the number be $x$.
According to the question,
$x+\frac{3}{x}=\frac{52}{7}$
$\Rightarrow 7x^2-52x+21=0$
$\Rightarrow (7x-3)(x-7)=0$
$\Rightarrow (7x-3)$ or $(x-7)=0$
$\Rightarrow x=7$ or $ \frac{3}{7}$
After checking the options, we get, $x=7$
Hence, the

Correct Answer: 299

Solution : $40 \times 7-2 \times\left(11^3 \div 11\right) \div 22+30$
$=40 \times 7-2 \times(11^2) \div 22+30$
$=40 \times 7-2 \times(\frac{11}{2}) +30$
$=40 \times 7-11 +30$
$=280-11 +30$
$=310-11$
$=299$
Hence, the correct answer is 299.
