Solutions:
1. B) From the table,
∴ The rate
of increase of users from the previous year of Redmi mobile users is the
highest in the year 2012.
2. B) From the
table,
Total
numbers of student users of Samsung mobiles = 900 + 1071 + 912 + 742 = 3625
∴ The
approximate average number of student users of Samsung mobile phones over the
years = 3625/4 = 906.25 ≈ 906.
3. B)
∴ The
numbers of users other than student users for Asus mobile phones is the highest
in the year 2014.
4. C) From the
table,
In
the 2013, the total numbers of Samsung mobile phones users = 2850
And
the numbers of students of Samsung mobile phones users = 2850 × (32/100) = 912
In
the 2013, the total numbers of Redmi mobile phones users = 3050
And
the numbers of students of Redmi mobile phones users = 3050 × (32/100) = 976
∴ The ratio
between the numbers of student users for Samsung and Redmi mobile phones
respectively in the year 2013 = 912:976 = 57:61.
5. A) From the
table,
The
total numbers of Asus mobile users in all given years = 1950 + 2200 + 2600 +
3200 = 9950
The
total numbers of Redmi mobile users in all given years = 1540 + 2450 + 3050 +
3600 = 10640
The
required percentage = (9950/10640) × 100 = 93.51
∴ The total
numbers of Asus mobile users is 93.51% of the total numbers of Redmi mobile
users in all years together.
(6 – 10): Explanation:
As
per the given information, we can create a table
6. B) Following
the common explanation, we get
Total
number of female reporters in studio P = 2052
Similarly,
in Q = 600
And,
Total number of female reporters in R = 1270
Similarly,
in S = 1460
Reqd
ratio = (2052 + 600)/(1270 + 1460) = 2652/2730 = 34 : 35
7. B) Following
the common explanation, we get
Total
no. of female computer operators in Q, R and S = 470 + 580 + 245 = 1295
Total
no. of male reporters in Q, R and S = 4530 + 2280 + 2540 = 9350
∴ Reqd average = (1295 + 9350)/3 = 10645/3 =
3548.33 ≈ 3548
8. E) The total
number of female operators in studio P = 456
Similarly,
In R = 580 and In S = 245
And,
The total number males reporters in P = 3598 and in S = 2540
∴ Reqd % = (456 + 580 + 245)/(3598 + 2540) ×
100 = 1281/6138 × 100 = 20.86 ≈ 21%
9. B) Total no.
of male reporters in studio P = 3598
Similarly,
in studio Q = 4530 and in studio R = 2280
Therefore,
total no. of reporters in studios P, Q and R together = 3598 + 4530 + 2280 =
10408
And
the total no. of male computer operators in studio P = 369
Similarly,
in studio Q = 640, In studio R = 620 and in studio S = 705
Therefore,
total no. male computer operators in studios P, Q, R and S together = 369 + 640
+ 620 + 705 = 2334
∴ Reqd difference =
10408 – 2334 = 8074
10. D) Following
the common explanation, we get
That
in the studio Q male reporters are maximum which is 4530
And,
in the studio S has the least female computer operators which is 245.
Hence,
option D is correct.
11. E) As per the
question,
15%
: 5200 :: 16% : Population of HP
∴ The total population of HP in 2014 = 5200 × 16/15 = 5546.6 ≈ 5547
∴ The total population of HP in
2015 = 110% of 5547 ≈ 6102
Population of the youth in HP = 55% of 6102 = 3356.1 ≈ 3356
Hence, option E is the correct answer.
12. B) As per the
question,
13%
: 9000 :: 8% : Population of AP
∴ The total population of AP in 2014 = 7800 × 8/13 = 4800
Population
of AP in 2016 = 4800 × 125/100 = 6000
Population
of UK in 2016 = 7800 × 85/100 = 6630
∴ Total population of AP
and UK in 2016 = 6000 + 6630 = 12630
13. D) The total
population of the youth in HR in 2014 = 48% of 13% of 45000 = 2808
Similarly,
the total population of the youth of WB = 18% of 51% of 45000 = 4131
∴ Required % = 2808/4131
× 100 = 67.97 ≈ 68%
14. A) As per the
question,
17%
of 58% : 2958 :: 13% : Total population of HR
Total
population of HR in 2014 = (2598 × 13 × 100)/(17 × 58) = 3900
15. E) The total
population of the youth in UP in 2014 = 58% of 3250 = 1885
Therefore,
the total population of the youth in WB
=
17% : 3250 :: 51% of 18% : Population of youth in WB
Youth
population of WB = (3250 × 51 × 18)/(17 × 100) = 1755
Reqd
ratio = 1855 : 1755 = 371 : 351
Hence,
option E is correct.
