The figure below shows road accessibility on the \(X\)-axis and hierarchy of roads on the \(Y\)-axis. The line which represents their correct relationship is .

Question

Auditorium capacity of 1200 with 1/3 females & 2/3 Male. WC requirement in integer is
Female: 3 per 100 Upto 200- 2 per 100 for 200 onwards
Male: 2 per 100 upto 400. I per 250 for 400 onwards

Answer 1

This question tests a basic transportation planning idea: how road hierarchy (expressway down to local street) trades off against accessibility (how easily vehicles can get on and off a road). Let's go through the marked lines one by one.

P: This line stays close to flat across the accessibility range, suggesting road hierarchy barely changes with accessibility. Real road networks do not behave this way: an expressway and a local street clearly differ hugely in both function and accessibility, so a flat line does not fit.
Q: This traces only a short, steep drop concentrated near the low-accessibility end of the graph, so it does not represent the relationship across the practical range from low to high accessibility that the question asks about.
R: This line rises from lower-left to upper-right, meaning hierarchy would increase as accessibility increases. That is backwards: real expressways, at the top of the hierarchy, are built with restricted access, not high access, so a rising line points the wrong way entirely.
S: This line falls steadily from high hierarchy at low accessibility down to low hierarchy at high accessibility, matching the standard planning principle that higher-order roads are designed for mobility and kept low on accessibility, while lower-order roads are designed for accessibility and sit low in the hierarchy.

The functional classification of roads is built exactly on this inverse relationship: as a road's job shifts from moving through-traffic to serving property access, its position in the hierarchy drops. That is the pattern line S shows.

Let's summarize:

Road hierarchy and road accessibility move in opposite directions: higher hierarchy means lower accessibility, and vice versa.
A flat line (P) or a rising line (R) both contradict this principle; only a consistently falling line fits.

So the line that correctly represents the relationship is S.
