To solve this problem, we need to find the price relative, using the year 1980 as the base year for the index calculation. A price relative is used to compare the price of a commodity at one point in time to another.
Here are the steps to calculate the price relative:

Identify the Prices :

Price in 1975 (P1) = ₹25
Price in 1980 (P0) = ₹30


Calculate the Price Relative : The formula to calculate the price relative is:
Price Relative = ( Price in 1980 Price in 1975 ​ ) × 100
Substituting the given values:
Price Relative = ( 30 25 ​ ) × 100
Price Relative = 0.8333 × 100
Price Relative = 83.33

Select the Correct Multiple Choice Answer : Based on the calculation, the price relative is 83.33, which is not listed as one of the specified multiple-choice options. Therefore, the correct choice is:
(d) None of these.


In conclusion, using 1980 as the base year, the price relative for the year 1975 is 83.33, indicating that in 1975, the price of the commodity was 83.33% of the price in 1980.
