Question 2:​​ The Number of students from different academic backgrounds taking admission in Law colleges from 1992-1998 have been given, Answer the questions based on the given data only.

2.1 In 1994 what is the percentage of science background students taking admission in LAW Schools?

(a)​​ 20%​​   (b) 26%​​   (c) 23%​​   (d) 27%

2.2​​ In which year the number of students reached 250?

(a) 1993​​   (b) 1994​​   (c) 1995  (d) 1996

2.3 In which year percentage growth​​ in​​ the​​ number of students is highest?

(a) ​​ 1993  (b) 1995  (c) 1996  (d)1998

2.4 What is the percentage of arts and commerce student together with respect to​​ the​​ total number of students in the year 1996?

(a) 65%​​   (b) 75%   (c) 55%   (d) 77%

2.5​​ What is the percentage of arts and commerce student together with respect to​​ the​​ total number of students?

(a) 76%   (b) 67%   (c) 75%   (d) 65%

Solution:​​ This is​​ a​​ simple observation based question that doesnâ€™t need any calculation; just focus on points where tea consumption (blue dot) is above coffee (orange dot)

Solution:​​ Change in consumption from 1995 to 2020; just do straight percentage calculation for the answer. Donâ€™t get confused with the shuffled answers of both commodities.

Percentage change in tea consumption = (35 â€“ 19) *100 / 19 = 84.77 %

Percentage change in coffee consumption​​ = (15 â€“ 23)*100 / 15 = 86.6667%

Solution: 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 donâ€™t mess it up.

 Year Tea Coffee Sum of both Percentage Change 1990 20 23 43 1995 19 15 34 -21% 2000 23 19 42 24% 2005 22 27 49 17% 2010 25 29 54 10% 2015 27 32 59 9% 2020 35 28 63 7%

Table 1.​​ 1

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

Solution:​​ Again​​ an​​ observation-based question, count the number of times both tea and coffee saw a decline in consumption and thatâ€™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.

Solution:​​ Highest consumption​​ in any year by any commodity (doesnâ€™t matter its tea or coffee) = 35

Total highest consumption = 35+28 = 63

Ratio = 35 / 63 = 5/9

Note:​​ If you read the question 2 completely, you will see that the question is calculation-intensive(sum and percentages with different conditions), therefore it is advised to at​​ least sum up​​ the​​ total number of students and simultaneously calculate percentage with the question.

A table with all the calculations is given below for your reference. All the calculations are based on this table only.

 Year Arts Commerce Science Total number of students Percentage Growth 1992 50 70 30 150 - 1993 65 95 40 200 33% 1994 70 90 55 215 8% 1995 85 115 50 250 16% 1996 90 135 75 300 20% 1997 110 130 85 325 8% 1998 125 165 105 395 22% Total Number of students(stream wise) 595 800 440 1835

Table 2.​​ 1

Solution:​​ Number of law students with science background in 1994 = 55

Total number of students in 1994 = 215

Percentage of science background students in 1994 = 55 * 100 /215 = 25.58% â‰ˆ 26%​​

Note: There are close options in question hence you should do​​ the​​ whole calculation, using Tricks can make answer wrong.

Solution:​​ Observation-based question, you would have done the sum in​​ the​​ initial stage only.

Total = Arts + Commerce+Science students​​

85+115+50 = 250

Solution:​​ For this question,​​ you will need to refer to the table 2.1 as you will need the calculation of​​ the​​ total number of students for all the year with percentages wrt to​​ the​​ previous year as this is​​ a​​ comparative question.

Solution:​​ No. of Arts background student in 1996 = 90

​​ ​​ ​​​​ No. of Commerce background student in 1996 = 135

​​ ​​​​ Sum of Arts and Commerce Background Student = 90 + 135 = 225

​​ ​​​​ Total Number of students in1996 = 300

Percentage of Arts and Commerce student in 1996 = 225*100/300 = 75%

Solution:​​ Similar to previous question, add number of students of both arts and commerce background and calculate the percentage wrt to total number of students across the years.

For calculation refer to table 2.1.
