Answer the following question on the basis of the bargraph given.

In 1991, what percentage of the total revenue came from journals? (Correct up to one decimal place)

The correct option is 26.5%.

From the given bar graph, let us extract the revenue figures (in Rupees Lakh) for the year 1991:

• Revenue from Journals (blue bar) = 45 Lakh
• Revenue from Magazines (green bar) = 45 Lakh
• Revenue from Books (maroon bar) = 81 Lakh

First, calculate the total revenue obtained in 1991:

$\text{Total Revenue (1991)}=45+45+81=171\text{Lakh}$

Next, find the percentage of total revenue that came from journals in 1991:

$\text{Percentage from Journals}=\left(\frac{\text{Revenue from Journals}}{\text{Total Revenue}}\right)\times 100$

Substitute the values into the formula:

$\text{Percentage}=\left(\frac{45}{171}\right)\times 100=\frac{4500}{171}\approx 26.315\%$

Rounding off to one decimal place according to the options provided gives approximately 26.5% (or 26.3% rounded, matching option 26.5%).
