d. Rs. 179 lakh

By analyzing the graph given in the question we can extract the following data: From the table above we can analyze the revenue obtained from magazines

The highest change in the revenue obtained from magazines is (39 – 31) = 8 in 1990.

Revenue from Journals in 1991 = 45 lakhs

Total revenue in 1991 = 169 lakhs

∴ required percentage = 45/169 × 100 = 26.6%

From the bar graph given, we can see that the revenue increased in all three categories in year 1990.

In 1991 it increased for two categories i.e. magazines and books whereas in year 1992 it increased only for 1 category i.e. magazines.

So the number of years in which revenue increased from at least 2 categories is 2 years (1990 and 1991)
