India has a very young population compared to many other nations. According to recent data, a significant proportion of Indians are below the age of 35, and the median age is around 28 years. This makes India one of the youngest countries in the world.
\[ \text{India's demographic pyramid is broad at the base, showing a large young population.} \]
This youthful population contributes greatly to India’s economic potential and workforce dynamism. To realize the demographic dividend, focus must be placed on education, skill development, and job creation.
\[ \textbf{India has a high youth proportion, making it a young and dynamic nation.} \]

In the following figure \(\triangle\) ABC, B-D-C and BD = 7, BC = 20, then find \(\frac{A(\triangle ABD)}{A(\triangle ABC)}\). 
The radius of a circle with centre 'P' is 10 cm. If chord AB of the circle subtends a right angle at P, find area of minor sector by using the following activity. (\(\pi = 3.14\)) 
Activity :
r = 10 cm, \(\theta\) = 90\(^\circ\), \(\pi\) = 3.14.
A(P-AXB) = \(\frac{\theta}{360} \times \boxed{\phantom{\pi r^2}}\) = \(\frac{\boxed{\phantom{90}}}{360} \times 3.14 \times 10^2\) = \(\frac{1}{4} \times \boxed{\phantom{314}}\) <br>
A(P-AXB) = \(\boxed{\phantom{78.5}}\) sq. cm.
