Correct Answer: 10 cm

Solution :
Given that $\frac{\text{area}(\triangle ABC)}{\text{area}(\triangle PQR)}=\frac{9}{4}$, BC = 15 cm, AB = 18 cm
$\triangle$ ABC ~ $\triangle$ QRP, hence the ratio of areas of two similar triangles is equal to the ratio of the square of their corresponding sides.
$\frac{\text{area}(\triangle ABC)}{\text{area}(\triangle PQR)}=\frac{BC^{2}}{PR^{2}}$
$⇒\frac{9}{4} =

Correct Answer: 1911-21

Solution : The correct option is 1911-21.

India witnessed a unique phenomenon of negative population growth rate from 1911 to 1921, which was mostly related to the catastrophic impact of the 1918 influenza pandemic, often known as the Spanish flu. This lethal epidemic has far-reaching implications for

Correct Answer: 4 hours

Solution : Given:
Distance between Delhi and Agra = 300 km
Speed of bus 1 = 38 km/h
Speed of bus 2 = 37 km/h

Here, both the buses are moving toward each other.

Relative speed = 38 + 37 = 75 km/h

Therefore, the time

Correct Answer: $\frac{1}{3}$

Solution : Given: $\sqrt{3} \tan \theta=3 \sin \theta$
⇒ $\sqrt{3}\times \frac{\sin \theta}{\cos\theta}=3 \sin \theta$
⇒ $\frac{\sqrt{3}}{3}=\cos\theta$
⇒ $\cos\theta=\frac{1}{\sqrt3}$
Squaring both sides of the above equation,
$\cos^2 \theta=\frac{1}{3}$ (equation 1)
We know the trigonometric identity, $\sin ^2 \theta+\cos ^2 \theta=1$.
Substitute the value from the equation 1 in

Correct Answer: Bone marrow

Solution : The correct answer is Bone marrow.

Haematopoiesis or the process of producing new blood cells occurs predominantly in bone marrow, which is found within the cavities of bones throughout the body. During haematopoiesis, bone marrow supplies the required microenvironment and components to promote blood

Correct Answer: Rs. 2,000

Solution : Here, Selling price of an object = Rs. 2,100
Here, $a$ = 40%, $b$ = –25%
Effective percentage change = $a+b+\frac{ab}{100}$%
= $40 − 25 −\frac{40\times 25}{100}$%
= $(15 - 10)$ = 5%
According to the question,
Let the cost price of the article
