Question

Match the following Curves in Group-I with their corresponding uses in Group-II.

 

• A. P–2, Q–3, R–4, S–5
• B. P–3, Q–1, R–5, S–2
• C. P–1, Q–2, R–3, S–4
• D. P–2, Q–1, R–5, S–4

Hint:

Curves like the Lorenz and Mass curves are essential in economics and traffic engineering for understanding distributions and transitions in various systems.

Answer 1

The Correct Option is D

P (Mass Curve) graphically depicts cumulative inflow (supply) and outflow (demand) over time. Match: P–2.
Q (Lorenz Curve) visually represents income or wealth inequality. Match: Q–1.
R (Density Curve) is an idealized distribution where the area under the curve equals 1. Match: R–5.
S (Horizontal Curve) facilitates a smooth transition between tangent roadway strips for turning. Match: S–4.
Therefore, the correct pairing is (D) P–2, Q–1, R–5, S–4.
