Direction (Q. 1-5): Study the following table carefully and answer the given questions.
A radio station surveyed 200 students to determine the types of music they liked. There are three types of music rock music, folk music and classical music. The survey revealed that 57 percent liked rock music, 25 percent liked folk music and 20.5 percent liked classical music, 14 students liked rock music and folk music, 15 students liked rock music and classical music, 6 students liked only classical music and folk music. 90 of them liked only rock music.
1). How many of them liked folk music but not rock music?

36
41
30
44
None of these

 

From the diagram, 114 – (14 -X+X+15 -X) = 114 – (29-X) = 90
∴ X = 90 – 85 = 5
Hence, 5 students liked all the three music.
The number of students liked only folk music = 50 – (9+5+6) = 30
The number of students liked only classical music = 41 – (10+5+6) = 20
1). Answer: A
The number of students like only folk music = 50 – (20) = 30
Hence, number of students liked folk music but not rock music = 30 +6 =36


2). How many of them liked any two types of music only?

15
16
19
25
None of these
2).Answer: D
The number of students liked rock& folk only = 14 – 5 = 9
The number of students liked folk& classical only = 6
The number of students liked classical& rock only = 15 – 5 =10
∴ Number of students who liked any two types only = 9 + 6 + 10 = 25


3). How many students did not like any of the three types?

35
40
30
25
20
3).Answer: C
The number of students who liked any one of the three types is,
90+30+20+ 9+6+10+5 = 170.
Hence, number of students who did not like any of the three types is,
200 – 170 = 30 students


4). What is the ratio of who liked rock and classical music together to the ratio of who liked only folk music?

5 : 1
31: 10
31 : 6
12 : 5
6 : 5
4).Answer: C
Required ratio = (rock + classical) : (only folk)
= (114+41) : 30 = 155 : 30
= 31 : 6


5). If 7 students liked all the three types of music then how many students liked only rock music?

88
92
89
91
86
5).Answer: B
Let X= 7,
114 – (14-X + X+15-X) = 114 – (14 -7+7+15-7) = 114 – 22= 92
Hence, 92 students liked only rock music.


Directions (Q. 6-10): Study the information carefully to answer the questions that follow:
In a shopping mall, there are three different varieties of dress materials Cotton, Silk and Chiffon. There are 300 customers visited the Shop. 50% of customers purchased Cotton material; 40% of customers purchased Chiffon material and 60% of customers purchased Silk material. The customers who purchased any of two dress materials are 90. 20% of customers who purchased Cotton also purchased other two materials. The customers who purchased only Silk material are 20 more than that of who purchased only Chiffon material. 30 Customers are purchased only Silkand Chiffon material.
6). How many of them purchased only one variety of dress material?

150
180
120
160
None of these

 

The number of customers purchased cotton material = 50/100 × 300 = 150
The number of customers purchased silk material = 60/100 × 300 = 180
The number of customers purchased chiffon material = 40/100 × 300 = 120
Given that, d+ e+ f = 90
∴ d+ e = 90 – 30 =60 ———– (1)
Also given, b = c + 20 ——— (2)
To find g,
20% of 150 = 20/100 × 150 = 30; g=30
To find a,
a + d + e + g = 150
a + 60 + 30 = 150
a = 150 – 90 = 60; a = 60
To find remaining variable,
b + d + g + f = 180
b + d + 30 + 30 = 180
∴ b + d = 120 ————– (3)
c + e + g + f = 120
c + e + 30 + 30 = 120
∴ c + e = 60 ————— (4)
Substitute (1), (2) and (4) in (3),
b + d = 120  (c +20) + (60 – e) =120
(60 – e +20) + (60 – e) = 120 e = 10
From (4), c + e = 60
c = 60 – e = 60 – 10
c = 50
Hence, b = c + 20 = 50 +20
∴ b = 70
And d = 60 – e = 60 – 10
∴ d = 50
6). Answer: B
a + b+ c = 60 + 70 + 50 = 180

7). How many of them purchased at least two types of dress materials?

90
100
120
140
None of these
7). Answer: C
The customers who purchased at least two types of materials
d + e + f + g = 10 + 50 + 30 + 30 = 120


8). What is the percentage of the customers who purchased only Silk material to that of the customers who purchased all types of dress material?

300.43%
305.53%
355.23%
233.33%
None of these
8). Answer: D
Required percentage = 70 / 30 × 100 = 233.33%


9). How many of them did not purchase any of the three types of materials?

10
15
5
Cannot be determined
None
9).Answer: E
The number of customers who purchased at least one type of material is,
60 + 70 + 50 + 10 + 30 + 50 + 30 = 300
The number of customers visited the shop = 300
Hence, all the customers are purchased the dress material.
So, the answer is option e) none.


10). How many of them did not purchase only Chiffon material?

180
120
150
330
None of these
10).Answer: A
Required answer = a + d + b = 60 + 50 + 70 = 180
