Official UPSC Answer KeyUPSC Prelims 1998 • Indian Economy

Correct Answer: Option (C) — weighted mean of price of certain items has increased 3.3 times

Concept & Option Breakdown

Standard Reference Verified

A price index is a weighted average (or weighted mean) of the prices of a representative basket of goods and services relative to a base period (where the base year index is set at 100). An index of 330 relative to a base of 100 means that the weighted mean price of that specific basket of items has increased by a factor of 3.3 times (or 230% increase) since 1960.

Elimination Heuristic & Exam Approach

Price indices are always constructed as 'weighted averages' of a specific basket of commodities, not simple unweighted changes across 'all' or individual items.
