The table shows the revenue (in lakh rupees) earned by a publishing house from the sale of journals, magazines and books during 2020 to 2023.

Year	Journals	Magazines	Books
2020	45	35	70
2021	47	40	80
2022	40	42	87
2023	40	54	79

In exactly how many of the years was there an increase in the revenue from at least two types of publications as compared to the previous year?

B2 ✓ Correct

Correct answer: (B) 2

Explanation

There were exactly two such years, so that is the answer.

From 2020 to 2021 journals, magazines and books all rose, so all three increased.

From 2021 to 2022 magazines and books rose while journals fell, so two increased.

From 2022 to 2023 only magazines rose, while journals stayed and books fell, so only one increased.

So the years with at least two increases are 2021 and 2022.

That makes exactly two years.
