Passage Based Questions: Quantitative Aptitude - 6 | Passage Based Questions for CLAT Preparation PDF Download

This is​​ a​​ simple observation based question that doesn’t need any calculation; just focus on points where tea consumption (blue dot) is above coffee (orange dot)

For​​ the​​ highest percentage increase in tea and coffee consumption together, add the yearly consumption of both and then calculate​​ the​​ yearly percentage increase.
You can do the write the sum of both directly on the graph itself but make sure you don’t mess it up.

From the table,​​ you can see​​ the​​ highest percentage change is in 2000

Highest consumption​​ in any year by any commodity (doesn’t matter its tea or coffee) = 35
Total highest consumption = 35 + 28 = 63
Ratio = 35/63 = 5/9

Change in consumption from 1995 to 2020; just do straight percentage calculation for the answer. Don’t get confused with the shuffled answers of both commodities.
Percentage change in tea consumption = (35 – 19) *100 / 19 = 84.77 %
Percentage change in coffee consumption​​ = (15 – 23)*100 / 15 = 86.6667%
Both the answers together will give option b as answer.

Again​​ an​​ observation-based question, count the number of times both tea and coffee saw a decline in consumption and that’s your answer. Here decline in tea happened twice: 1995 & 2005 and​​ a​​ decline in consumption of Coffee happened twice in 1995 & 2020. Hence answer is 4.
