Correct Answer: $\mathrm{\frac{AD+BC}{AD }}$

Solution :

The area of a trapezium,
$\text{Area} = \frac{1}{2} \times (\text{sum of parallel sides}) \times \text{height}$
$\text{Area}_{ABCD} = \mathrm{\frac{1}{2} \times (AD + BC) \times EF}$
The area of triangle AED,
$\text{Area}_{AED} = \mathrm{\frac{1}{2} \times AD \times EF}$
The ratio of the area of ABCD to that of AED,
$\mathrm{\frac{\text{Area}_{ABCD}}{\text{Area}_{AED}} = \frac{\frac{1}{2} \times (AD + BC) \times EF}{ \frac{1}{2} \times AD \times EF} = \frac{AD + BC}{AD}}$
Hence, the correct answer is $ \mathrm{\frac{AD + BC}{AD}}$.

Correct Answer: 3

Solution : The correct choice is the third option.

The phrase not make economic sense should replace not to make economic sense, as modal verbs are to be followed by the base form of the main verb. Here, would is a modal verb and it should be followed by the base form of the main verb, make.

So, the correct sentence is: Internet providers would not block content because it would not make economic sense and consumers would stand for it.

Correct Answer: Body

Solution : Given:
Cells : Tissue :: Organs : ?

Like, a group of cells forms tissues.
Similarly, a group of organs forms a body.

Hence, the third option is correct.

Correct Answer: 2 km

Solution : Let the distance be $x$ km.
According to the question,
Speed = $\frac{\text{Distance}}{\text {Time}}$ 
$\frac{x}{3}–\frac{x}{4}=\frac{5+5}{60}$
⇒ $x=2$
Hence, the correct answer is 2 km.

Correct Answer: 24125

Solution : According to the question, 75% of the T-type cars are sold.
Now, if 75% of the T-type cars produced each year were sold by the company, the number of T-type cars remain unsold
= 350000 $\times$ (90 – 75)% $\times$ (100 – 75)% $+$ 440000 $\times$ (95 – 85)% $\times$ (100 – 75)%
= 24125
Hence, the correct answer is 24125.

Correct Answer: rainfall

Solution : The correct option is - rainfall

The maximum and minimum temperatures, temperature range, total and seasonal distribution of precipitation, and other factors are used to classify the climatic zones. The most well-known classification scheme was initially created by Wladimir Koppen based on these parameters.

Correct Answer: –2197

Solution : $\frac{r}{13}+\frac{13}{r}=1$
We know that if $x+\frac{1}{x} = 1$, then $x^3 = -1$
Let $\frac{r}{13} = x$
The equation becomes,
$x+\frac{1}{x} = 1$
⇒ $x^2-x+1=0$
$x^3+1^3=(x+1) (x^2-x+1)$
⇒ $x^3+1^3 =0$
⇒ $x^3 = -1$
⇒ $(\frac{r}{13})^3 = -1$
⇒ $r^3 = -2197$
Hence, the correct answer is –2197.

Correct Answer: Coagulation

Solution : The correct answer is coagulation. 

When the suspended particles in any liquid solution form a precipitate and settle down, then this process is known as coagulation. The most common example of it is coagulation of blood which forms a blood clot and stops bleeding. Similarly when alum is added to the muddy water it reacts with the impurities of the water and forms a solid precipitate which settles down at the bottom of water along with all the suspended dust particles. 

Correct Answer: 25

Solution : Given:
45 : 15 :: 20 : 10 :: 125 : ?

Like, 45 : 15→(45 × 5) = 225; √225 = 15
20 : 10→(20 × 5) = 100; √100 = 10
Similarly, follow the same pattern for 125 : ?→(125 × 5) = 625; √625 = 25

So, 25 is related to 125. Hence, the second option is correct.

Correct Answer:

Solution : As per the mirror image properties, closer things appear closer to the mirror in the reflection.
So, according to the above property and the information provided, the mirror is placed on the right side of the figure (on line MN). So, the left side of the reflected image will appear as the right side and the right side will appear as the left side. However, the top and bottom of the reflected image will remain the same.

Thus, the correct mirror image of the given figure will be –

Hence, the second option is correct.
