Correct Answer: CBDA

Solution : The correct choice will be the second option.

C. Mechanical production of goods leads to uniformity of design.
B. However, uniformity does not imply a lack of taste.
D. In fact, popular taste has improved because standardised goods of better design are now accessible.
A. Expert designers standardise basic designs, leaving scope for the satisfaction of individual taste.

Therefore, the correct answer will be CBDA.

Correct Answer: 220 sec

Solution : P beats Q by 120 metres or 30 sec, which means Q covers 120 m in 30 sec.
Speed of Q = $\frac{120}{30}=4$ m/s
Time taken to cover 1000 m = $\frac{1000}{4} = 250$ sec
P beats Q by 30 seconds, which means P reached 30 seconds early.
Time taken by P to complete the race = 250 – 30 = 220 sec.
Hence, the correct answer is 220 sec.

Correct Answer: Carbon dating

Solution : The correct option is Carbon dating.

The process of using radiation to establish the age of prehistoric items is known as "radiocarbon dating" or "carbon dating." This approach estimates the age of organic materials by using the decay of radioactive carbon isotopes. It specifically examines the decay of carbon-14 (14C) to determine how long the substance has been in a live body.

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.
