Fixed charge = ‘x’ Say
Variable charge = Rs y per km
⇒ x + 16y = 156 → (1)
x + 24y = 204 → (2)
By solving (1) & (2),
x = 60, y = 6
⇒ Cost for travelling distance of 30 km = 60 + 3y
= 60 + 3(6)
= Rs 240

       Mathematical-Reasoning       Averages       2015 December NTA UGC NET Paper 1
Question 63 Explanation: 
Given data:
Total number of students = 210
1/3 rd of 210 = 70 students
Mean marks of 70 students = 60
To Find: Mean of the whole group= ?
Let the sum of marks of 70 students be X
Mean = X / Number of students
60 = X/70
X = 70*60

⇒ Sum of marks of 70 students = 4200
Remaining students = 210 - 70 = 140 students
Mean of 140 students = 78
Sum of marks of 78 students = 140*78 = 10920
Total marks of 210 students = 4200 + 10920
= 15120
Mean of whole group = 15120 / 210
= 72 marks

Question 129 Explanation: 
1600 Years contains ‘0’ odd day.
300 Years contains ‘1’ odd day.
93 Years = 23 leap years + 70 ordinary years
= (46 + 70) odd days
= 116 odd days
= 4 odd days

No. of days upto 1st April, 1994
31 + 28 + 31 + 1 = 91 days [0 odd days]
Total odd days = (0 + 1 + 4 + 0) = 5
Day on 1st April is (Sunday + 5) = Friday
The fridays fall on = 1, 8, 15, 22, 29
The Sundays fall on = (1+2), (8+2), (15+2), (22+2), (29+2)

Question 184 Explanation: 
It can be observed that the difference between two consecutive terms is increasing by adding 4
in the previous difference.
So for next term, next difference will be 14+4= 18
Next term = 29 + 18
Next term = 47

       Mathematical-Reasoning       Ratio-and-Proportion       UGC-NET CS 2018 JUNE Paper-1
Question 188 Explanation: 
x/y = 2/5
⇒ x = (2 /5 )y ------(1)
(x+16)/(y+16)= 1/ 2
2 x + 3 2 = y + 1 6
Put value of ′ x ′ from eqn.(1) into above eqn.
2 ( (2 /5) y ) + 3 2 = y + 1 6
4 y + 160 = 5 y + 8 0
y = 80
Put value of ′ y ′ in eqn.(1)
x = (2/5) × 80
x = 3 2

A
10%
B
15%
C
20%
D
25%
       Mathematical-Reasoning       Percentage       UGC-NET June CS 2019 Paper 1
Question 194 Explanation: 
Let the price of the petrol is 100
It’s prices is increased by 25% then new price is 125.
Let Percentage of decrease of consumption =X
Then 125*X /100=25
⇒ X=2500/125
⇒ 20%

Assume the initial sum is x,
After six years, the amount becomes double which is 2x
After 12 years, again the amount is double(compound interest), which is 4x
After 18 years, again the amount is double(compound interest), which is 8x
After 24 years,again the amount is double(compound interest), which is 16x
Question 197
Oar is to rowboat as foot is to
A
running
B
sneaker
C
skateboard
D
jumping
       Mathematical-Reasoning       Analogy-Test       UGC-NET June CS 2019 Paper 1
Question 197 Explanation: 
An oar puts a rowboat into motion.
A foot puts a skateboard into motion.
The answer is not choice (a), because running is not an object that is put into motion by a foot.
Sneaker (choice b) is incorrect because it is something worn on a foot.
Jumping (choice d) is incorrect because although you do need feet to jump, jumping is not an object that is put into motion by means of a foot.
Question 198
If 152 is divided into four parts proportional to 3,4,5 and 7, then the smallest part is
A
29
B
26
C
25
D
24
       Mathematical-Reasoning       Number-Theory       UGC-NET June CS 2019 Paper 1
Question 198 Explanation: 
Given four proportional are 3x,4x,5x,7x.
Four proportional are divided into 152.
3x+4x+5x+7x=152
19x=152⇒ x=8
The smallest proportional is 3x=3x8=24

C
35.5%
D
38.8%
       Mathematical-Reasoning       Profit-and-Loss       UGC-NET Dec 2019 Part-1
Question 201 Explanation: 
Single equivalent discount for successive discounts of 10% and 15%.
= (10+15- (15*10)/100)%
= 23.5%
Single equivalent discount for 23.5% and 20%
=(23.5+20-(23.5*20)/100)%
=38.8%

Question 203

The sum of a number and its inverse is –4. The sum of their cubes is:

A
-52
B
52
C
64
D
-64
       Mathematical-Reasoning       Number-Theory       UGC-NET Dec 2019 Part-1
Question 203 Explanation: 
Given : a + 1/a = - 4
Find: a^3 + (1/a)^3
Solution: a + 1/a = -4
Take cube on both sides
(a + 1/a)^3 = (-4)^3
a^3 + (1/a)^3 + 3*a* 1/a (a+1/a) = -64
a^3 + (1/a)^3 + 3(a+1/a) = -64
a^3 + (1/a)^3 - 12 = -64
a^3 + (1/a)^3 = - 64 + 12
a^3 + (1/a)^3 = -52
