Step 1: Understanding Golden Quadrilateral
The Golden Quadrilateral (GQ) is a highway network in India that connects four major metropolitan cities: Delhi, Mumbai, Chennai, and Kolkata, forming a quadrilateral.
Step 2: Purpose of the project
It was launched under the National Highways Development Project (NHDP) in 2001, with the objective of improving road connectivity, reducing travel time, and boosting economic activities.
Step 3: Mode of transport
Since it is a highway network, the Golden Quadrilateral is associated with road transport.
Step 4: Conclusion
Thus, the correct answer is:
\[
\boxed{\text{Road Transport}}
\]
Find the unknown frequency if 24 is the median of the following frequency distribution:
\[\begin{array}{|c|c|c|c|c|c|} \hline \text{Class-interval} & 0-10 & 10-20 & 20-30 & 30-40 & 40-50 \\ \hline \text{Frequency} & 5 & 25 & 25 & \text{$p$} & 7 \\ \hline \end{array}\]
Two concentric circles are of radii $8\ \text{cm}$ and $5\ \text{cm}$. Find the length of the chord of the larger circle which touches (is tangent to) the smaller circle.
