What is the central angle of the sector corresponding to the expenditure incurred on Royalty ?
A
15​ 0
B
24​ 0
C
54​ 0
D
48​ 0
Question 5 Explanation: 
According to Diagram the circle is in the form of 360°
From that Diagram Expenditure incurred on Royalty is 15%
ஃ 360*(15/100) = 54°
Question 6
The following pie-chart shows the percentage distribution of the expenditure incurred in publishing a magazine. Study the pie-chart and answer the questions based on it.

The price of the magazine is marked 20% above the C.P. If the marked price of the magazine is ₹ 180, then what is the cost of the paper used in a single copy of the magazine?
A
₹ 36
B
₹ 37.50
C
₹ 42
D
₹ 44.25
Question 6 Explanation: 
Let’s C.P = x
M.P = 120 x / 100
From that question M.P of Magazine is = 180/-
Cost of the paper in a single copy = ?
From the above details we have to find out C.P first
180 x = x (120 x / 100)
After solving this
x = 150
Cost of the paper in a single copy
= 150 * (25/100)
= 37.50
Question 7
The following pie-chart shows the percentage distribution of the expenditure incurred in publishing a magazine. Study the pie-chart and answer the questions based on it.

C
₹ 22950
D
₹26,150
Question 7 Explanation: 
Printing Cost=30,600/- that means 20% according to Diagram
Royalty cost=x
∴20 % →30,600
15% →x
Do Cross Multiplication
(20/100) * x=30,600 * (15/100)
x=22,950/-
Question 8

A
5%
B
33 (1 / 5 )
C
20%
D
25%
Question 8 Explanation: 
According to Diagram
Printing Cost = 20%
Royalty Cost = 15%
How much percentage royalty cost is less than printing cost
((20-15) / 20 ) * 100 = 50/2 = 25%
Question 9
The table given here shows production of five types of cars by a company in the year 2010 to 2015. Study the table and answer the questions.

P+Q in 2011 -----> 20+10 = 30
R+S in 2011 ------> 17+6 = 23
option A is wrong
P+Q in 2012 ----> 16+14 = 30
R+S in 2012 ----> 16+10 = 26
option B is wrong
P+Q in 2015 ---> 6+14 = 20
R+S in 2015 ---> 31+8 = 39
option C is wrong
So finally option D is correct.
Question 10

2012
C
2014
D

A
S
B
R
C
Q
D
P
Question 11 Explanation: 
From that table in 2014 total production of cars was 80.
So,
100% -----> 80
25% ------> x
(25 * 80) / 100 = 20.
From that table 20 cars are from Type S .

Difference between their age is = 28
12x - 5x = 28
x= 4
Substitute x value in (i) and (ii)
Father’s present age = 48
son’s present age = 20
Ratio of their ages after eight years
Father’s age : Son’s age
48+8 : 20+8

Question 44
A train started from Mumbai at 6.00 A.M. On the next (second) station 1/3 passengers got down and 96 got in. On the next (third) station, 1⁄2 of the total passengers present in the train, got down and 12 came in. Now there were 248 passengers in the train, when the train started from Mumbai, the number of passengers was :
A
435
B
564
C
654
D
736
Question 44 Explanation: 
Let’s take number of passengers in a train = x
on second station 1⁄3 rd passengers got down and 96 got in = (x - (x/3)) + 96
on third station 1⁄2 got down and 12 got in = (((x-(x/3))+96)/2)+12 Now there were 248 passengers
(((x-(x/3))+96)/2)+12 =248
x=564
Question 45
The LCM of two numbers is 45 times their HCF. If the sum of the LCM and the HCF of these two numbers is 1150 and one of the numbers is 125, then the other number is :
A
256
B
225
C
250
D
255
Question 45 Explanation: 
Let the lcm be x and hcf be y and the other number be z.
Given lcm of 2 numbers is 45 times their hcf, the sum of HCF + LCM is 1150.
y = 45x. ---- (1)
x + y = 1150 --- (2)
Substitute equation (1) in (2), we get
46x = 1150
x = 25.
Substitute x = 25 in (1), we get
y = 45 * 25 = 1125.
We know that product of two numbers = LCM * HCF
125 * z = 25 * 1125
z = 25 * 1125/125 = 225.
The other number = 225.
Question 46
Find out the wrong term from the following series and select the number from the alternatives which will replace the wrong term in the series.

299, 178, 97, 48, 24, 14, 13 :

B
295
C
23
D
10
Question 46 Explanation: 
From that sequence we found out
-121, -81, -49, -24, -10, -1.
From the above sequence 24 is replace with 23.
So we get perfect sequence.
Question 47
Find out the wrong term from the following series and select the number from the alternatives which will replace the wrong term in the series.

2, 9, 28, 126, 216, 344 :
A
38
B
217
C
356
D
66
Question 47 Explanation: 
1^3 + 1 = 2
2^3 + 1 = 9
3^3 + 1 = 28
4^3 + 1 = 65
5^3 + 1 = 126
But
6^3 + 1 = 217 and,
Given is 216 so its odd or wrong.
7^3 + 1 = 344.
Question 48
The ratio between Sumit’s and the Prakash’s age at present is 2 : 3. Sumit is 6 years younger than Prakash. The ratio of Sumit’s age to Prakash’s age after six years will be
A
1 : 2
B
2 : 3
C
3 : 4
D
3 : 8
Question 48 Explanation: 
Sumit’s age = 2x
Prakash’s age = 3x
Sumit is 6 years younger than Prakash means
Prakash = Sumit + 6
Prakash - Sumit = 6
3x - 2x = 6
x = 6
So, Sumit’s age = 12
Prakash’s age = 18
Ratio of Sumit’s age and Prakash’s age after six years
12+6 : 18+6
18 : 24
3 : 4
Question 49
Two pipes A and B can fill a water tank in 20 and 24 minutes respectively and third pipe C can empty at the rate of 3 gallons per minute. If A, B and C opened together filed the tank in 15 minutes, the capacity (in gallons) of the tank is :
A
60
B
120
C
150
D
180
Question 49 Explanation: 
Work done by the waste pipe in 1 minute
= (1/15) - ((1/20) + (1/24))
= -1/40 (Negative means it’s emptying)
Volume of the 1/40 = 3 gallons = (40 * 3) = 120 gallons
Question 50
A can run 200 m in 35 seconds and B in 38 seconds. By what distance A beats B ?
A
15m
B
15 (2/3)m
C
15 (15/19)m
D
15 (4/19)m
Question 51
A train starts at 7 a.m. from A towards B with a speed of 50 km/hr. Another train from B starts at 8 a.m. with a speed of 60 km/hr towards A. Both of them meet at 10 a.m. at C. The ratio of the distances AC to BC is :
A
4 : 5
B
5 : 4
C
5 : 6
D
6 : 5
Question 51 Explanation: 
Distance covered by A in 3 hours with the speed of 50 km/ h is = 50 *3 = 150km
Distance covered by B in 2 hours with the speed of 60 km/ h is = 60 * 2 = 120km =120 km
then AC:BC = 150:120 =5:4

B
₹ 550
C
₹ 484
D
₹ 460
Question 54 Explanation: 
From that question A + B = 1210 ---> (i)
(4/15) A = (2⁄5) B ---> (ii)
(2⁄3) A = B ---> (iii)
Sub (iii) in (i)
A + (2A/3) = 1210
A = 726 (Sub A value in (i) )
So,
B = 484
Question 55

Question 56
Two dice are thrown simultaneously. The probability of obtaining a total score of 5 is :
A
1/18
B
1/12
C
1/9
D
None of these
Question 56 Explanation: 
Probability of obtaining a total score of 5 is {(1,4)(2,3)(3,2)(4,1)} = 4
Total Probability = 6 * 6 = 36
P(E) = 4 / 36 = 1 / 9
Question 57
A tradesman marks his goods at such a price that after allowing a discount of 15%, he earns a profit of 20%. Find the marked price of an article which costs him ₹ 850.
A
₹ 1200
B
₹ 1300
C
₹ 1250
D
₹ 1350
Question 57 Explanation: 
C.P = 850
M.P = x
Discount = 15%
S.P = x - (15x/100) = 85x / 100
S.P
= 120% of C.P
= (120/100) * 850
= 85 * 12
= 1020
Therefore S.P = (85X/100) = 1020
X = 1200
Question 58
In a camp, there are meals for 120 men or 200 children. If 150 children have taken their meals, how many men will be catered to with the remaining meal ?
A
50
B
40
C
30
D
20
Question 58 Explanation: 
There is a meal for 120 men and 200 children.
150 Children already taken meal. 50 Children remaining can also take a meal
200 Children = 120 men
50 Children = (120/200) * 50
= 30
Question 59
56 men can complete a piece of work in 24 days. In how many days can 42 men complete the same piece of work ?
A
48
B
32
C
20
D
16
Question 59 Explanation: 
1 Men 1 Day work = (1/(56 *24))
42 Men in how many days = (1/(56 *24)) * 42 = 1/32
So,
42 Men can complete piece of work in 32 days.
Question 60
A boat travels upstream from P to Q and downstream from Q to P in 4 hours. If the speed of the boat in still water is 12 km/hr and the speed of the current is 4 km/hr, then what is the distance from P to Q ?
A
31 (1/ 3) km
B
41( 1/ 3) km
C
21 (1 /3) km
D
11 (1/ 3) km
Question 60 Explanation: 
Speed of the boat in still water = 12 km/hr
Speed of the current = 4 km/hr
Speed of the upstream = 12 + 4 = 16 km/hr
Speed of the Downstream = 12 - 4 = 8 km/hr
Let the distance between P and Q be x
(x/16) + (x/8) = 4
x = 64 / 3
x = 21 (1⁄3)
