 Maths Questions in UGCNET/JRF 2017 exam
 Data Interpretation in UGC NET exam: How to prepare?
 RC Passage: literature, partition and great war
Maths Questions in UGCNET/JRF 2017 exam
 In NET exam, UGC asks hardly 1 or 2 MCQs from basic maths. [and 6 from DI, 6 from RC and ~10 from reasoning]
 Unlike other competitive exams, in UGC you don’t have to prepare entire maths but only following topics:
 Linear equation (coin problems, age problems etc.) usually in two variables (x,y). only this year, UGC asked linear equation in three variables (x,y,z). but quite easy calculation as you can see below.
 Percentages, Profitloss, Discount, product consistency rule.
 Averages: Both simple and weighed average. (But ignore alligiations it’s not asked).
 Pipes and cisterns. (only occasionally asked)
 How to prepare Mathematics for future exams? If you’re already preparing for exams such as UPSC, SSC or Banking then no separate preparation required here. Same books / material will suffice. If you’ve no book, then I would recommend FastTrack to objective arithmetic by Rajesh Verma
Anyways, let’s solve the MCQ asked in Jan’17 paper:
Q1. Imtiyaz Ali buys a glass, a pencil box and a cup and pays ₹ 21 to to the shopkeeper. Rakesh Roshan buys a cup, two pencil boxes and a glass and pays ₹ 28 to the shopkeeper. Preeti Zinta buys two glass, a cup and two pencil boxes and pays ₹ 35 to the shopkeeper. the cost of 10 cups will be?
 40
 60
 80
 70
Imtiyaz Ali  1g+1p+1c=21 
Rakesh Roshan  1g+2p+1c=28 
Preeti Zinta  2g+2p+1c=35 
Rakesh minus Ali =>p=7; substitute values
Preeti minus Rakesh=> g=7.
Substitute these values in Ali’s equation, you get c=7.
Therefore, cost of 7 cups will be 7 x 10 = 70 rupees.
Data Interpretation Qs in UGC NET exam: How to prepare?
UGC Trend 3 years ago  Nowadays 

One set with 6 MCQs. 

quick and simple pie charts and single digit divisions 

 People who take exam casually, rely on following strategy: RC+DI = 6+6=12 Qs तो मैं पक्का करके आऊंगा.. But due to lack of practice, and lengthiness of the sets, they waste 40 minutes on 12 Questions only.
How to prepare Data Interpretation for future UGCNET exams?
 As such no special book required. The level of these RC and DI are a bit higher than SSC and a notch lower than Banking exams.
 So just solve previous papers of UGCNET/JRF, SSC and Bank exams, and you’d have sufficient skill over these two segments.
Anyways, let’s solve two data sets theyasked in January 2017’s NET exam
DISET#1: virus corrupted HDD
A University professor maintains data on MCA students tabulated by performance and gender of the students. The data is kept on a computer had disk, but accidentally some of it lost because of a computer virus. Only the following could be recovered:
Gender  Average  Good  Excellent  Total 

Male  10  
Female  32  
Total  30 
Panic buttons were pressed but to no avail. An expert committee was formed, which decided that the following facts were selfevident:
 Half the students were either excellent or good.
 40% of the students were females
 Onethird of the male students were average
Filling the missing values
Before we can solve the questions, we’ve to fillup the missing values in above table, using “selfevident” facts, we know that:
Gender  Average  Good  Excellent  Total 

Male  M ÷ 3  10  M (60% of total)  
Female  32(40% of total)  
Total  30 
FactB: Since 40% of students are females; so male are 60%: 60/40=m/32=>m=48. update the table
Gender  Average  Good  Excellent  Total 

Male  48 ÷ 3=16  10  48  
Female  32  
Total  30  80 
FactA: Half the students were either excellent or good.
Since total students are 80, so 40 are (either excellent or good.) and within them 30 are good. So no. of excellent students are 4030=10. only. Now fillup the missing values in the cells.
Gender  Average  Good  Excellent  Total 

Male  16  (481610)=22  10  48 
Female  328=24  (3022)=8  0  32 
Total  40  30  10 (FactA)  80 
Now our table is complete, so let’s solve the questions
Q1: How many female students are excellent?
 0
 8
 16
 32
Answer: ZERO female students are excellent!! Where are thehindu columnists to criticize this misogynistic / “trumpwaadi” mindset walla examiner? Had UGC asked any question about Cow, then indeed these columnists have jumped into their britches to critisise the saffornization of higher education!
Q2. What proportion of female students are good?
 0
 0.25
 0.50
 0.75
8 good females ÷ 32 Total females = 8/32=0.25
Q3. Approximately, what proportion of good students are male?
 0
 0.73
 0.43
 0.27
22 good males ÷ total 30 good students= 0.73
DI SET #2: Publication revenue
The table below embodies data on the sales revenue (in lakh) generated by a publishing house during the years 201215 while selling books, magazines and journals as three categories of items. Answer the questions based on the data contained in the table.
item  2012  2013  2014  2015 

Journals  46  47  45  44 
Magazines  31  39  46  51 
Books  73  77  78  78 
Total 
Q1). The number of years in which there was an increase in revenue from at least two categories of items, is
 0
 1
 2
 3
This happens only twice
 2013 (over 2012) : sales of all items increased
 2014 (over 2013): sales of only two items increased
 2015 (over 2014): journals declined, magazines increased and books stagnant.
So only in two years (2013 and 2014), we see increase in the revenue from at least two categories.
Q2). If the year 2016 were to show the same growth in terms of total sales revenue as the year 2015 over the year 2014, then the revenue in the year 2016 must be approximately :
 194 lakh
 187 lakh
 172 lakh
 177 lakh
Let’s update the table:
item  2014  2015  2016 

Journals  45  44  
Magazines  46  51  
Books  78  78  
Total  169  173  A 
Let “A” be the total sales in 2016.
IF % wise the growth is same for 201415 and 201516 then, the ratio should also be same. i.e.
Sales of [2014 ÷ 2015]= sales of [2015 ÷ 2016] (169 ÷ 173)=(173 ÷ A)
A=(173*173) ÷ 169
In calculator or mobile, we can easily solve this but in actual exam, both are prohibited! So how to proceed?
You should know that square of 13=169. therefore,
A=(173/13)*(173/13)
Only once you do manual two digit division and it turns out 173/13=13.3
A=13.3 x 13.3
A=~177 lakh.
Q3). In 2015, approximately what percent of total revenue came from books ?
 45%
 55%
 35%
 25%
From previous question, we know the total sales in 2015 are 173.
So, out of them books are %=(78/173) x 100
Again, we can’t use calculator or mobile in real exam, so how to do a three digit division by hand!?
You know that 173<180.
So when we are dividing a number with them as denominators: a/173 > a/180
now let’s try guestimation:
This will be bigger  This will be smaller 

78*100/173  78*100/180 
(13 x 6) x 100 / (6 x 3 x 10)  
130/3  
From the options, the nearest big amount than 43% is 45%. Hence our answer is 1)  43.33% 
Cross check from calculation: (78/173) x 100=45.08% so our answer is correct.
RC Passage: literature, partition and great war
 In January 2017 UGCNET/JRF paper, they asked single passage with 6 MCQs
 For convenience in referencing, I’ve given bullet numbers to the statements.
Read the passage carefully and answer following questions
 The last Great War, which nearly shook the foundations of the modern world had little impact on Indian Literature
 beyond aggravating the popular revulsions against violence and
 adding to growing disillusionment with the ‘humane pretensions’ of the Western World.
 This was eloquently voiced in Tagore’s poems and his last testament, ‘Crisis in Civilization’.
 The Indian intelligentsia was in a state of moral dilemma.
 On the one hand, it could not help but sympathize with
 the England’s dogged courage in the hour of peril,
 with the Russians fighting with their backs on the wall against ruthless Nazi hordes, and
 with the China groaning under the heel of Japanese militarism;
 on the other hand their own country was practically under the military occupation of their own soil and the Indian army under Subhas Bose was trying from the opposite camp to liberate their country.
 On the one hand, it could not help but sympathize with
 No creative impulse could issue from such confusion of loyalties.
 One would imagine that the achievement of Indian independence in 1947, which came in the wake of the Allies victory and was followed by collapse of colonialism in the neighboring countries of South East Asia, would have released an upsurge of the creative energy.
 No doubt it did, but it was soon submerged in the great agony of partition with
 the inhuman slaughter of innocents and the uprooting of the millions of the people from their homeland
 followed by the martyrdom of Mahatma Gandhi.
 These tragedies along with Pakistan’s Invasion of Kashmir and its later atrocities in Bangladesh, did indeed provoke a pregnant writing,
 particularly in the languages of the regions most affected Bengali, Hindi, Kashmiri, Punjabi, Sindhi and Urdu.
 Both poignant or passionate writing does not by itself make great literature.
 What reserves of enthusiasm and confidence served these disasters have been mainly absorbed in the task of national reconstruction and economic development.
 Great literature has always emerged out of chains of convulsions. Indian literature is richer today in terms of volume, range and variety than it ever was in past.
Q1) What was the impact of the last great war on Indian literature?
 It had no impact
 It aggravated popular revulsion against violence
 It shook the foundations of literature
 It offered eloquent support to the Western World
Read passage sentence no. 1/A. hence answer is B.
Q2) What did Tagore articulate in his last testament?
 Offered support to Subhas Bose
 Exposed the humane pretensions of the Western World
 Expressed loyalty to England
 Encouraged the liberation of countries
Read passage sentence no. 1/b and 1/c. hence answer is B.
Q3) What was the stance of Indian intelligentsia during the period of great war?
 Indifference to Russia’s plight
 They favored Japanese militarism
 They prompted creativity out of confused loyalties
 They expressed sympathy for England’s dogged courage.
We’ve to go by elimination. Read passage sentence no. 2 and 3 and accordingly answer choice 1 to 3 are eliminated.
We are left with answer D.
Q4) Identify the factor responsible for the submergence creative energy in India literature.
 Military occupation of one’s own soil
 Resistance to colonial occupation
 Great agony of partition
 Victory of Allies
Read passage statement 5. hence answer is C.
Q5) What was the aftermath that survived tragedies in Kashmir and Bangladesh?
 Suspicion of other countries
 Continuance of rivalry
 Menace of war
 National reconstruction
Read passage sentence no.8. hence answer is D.
Q6) The passage has the message that
 Disasters are inevitable
 Great literature emerges out of chains of convulsions
 Indian literature does not have a marked landscape
 Literature has no relation with war and independence.
Read passage sentence no. 9. hence answer is B.
