Books publishers | Novels : Biography

P → 16 : 7
Q → 3 : 5
R → 6 : 7
S → 13 : 11
T → 21 : 23

Ques: What is the total number of books published by P, R, and T?

Correct Answer: (b) 1704
Solution:

Total books published = 2400
Books published by P = (23/100) × 2400 = 552
Novels published by P = (16/23) × 552 = 384
Biographies Published by P = (7/23) × 552 = 168

Books published by Q = (11/100) × 2400 = 264
Novels published by Q = (3/8) × 264 = 99
Biographies Published by Q = (5/8) × 264 = 165

Books published by R = (26/100) × 2400 = 624
Novels published by R = (6/13) × 624 = 288
Biographies Published by R = (7/13) × 624 = 336

Books published by S = (18/100) × 2400 = 432
Novels published by S = (13/24) × 432 = 234
Biographies Published by S = (11/24) × 432 = 198

Books published by T = (22/100) × 2400 = 528
Novels published by T = (21/44) × 528 = 252
Biographies Published by T = (23/44) × 528 = 276

Total number of books published by P, R, S and T
= 552 + 624 + 528 = 1704

72. What is the difference between the Sum of the Biographies published by S and Novels published by Q and the Biographies published by P?

Correct Answer: (c) 129
Solution:Novels published by Q = 99
Biographies published by S = 198
Sum = 99 + 198 = 297
Biographies published by P = 168
Difference = 297 - 168 = 129

73. What are the average biographies published by Q, R, and T?

Correct Answer: (d) 259
Solution:Biography published by Q = 165
Biography published by R = 336
Biography published by T = 276
Average biographies published by Q, R and T
= (165 + 336 + 276) / 3
= 777 / 3 = 259

74. Total number of novels published by R and T together are approximately what percentage of total number of biographies published by S?

Correct Answer: (e) 273%
Solution:Total number of Novels published by R = 288
Total number of Novels published by T = 252
Sum = 288 + 252 = 540
Total number of biographies published by S = 198
Required percentage = (540/198) × 100
= 3000/11
= 272.72% ≈ 273%

75. What are the total number of Novels published by all the publishers?

Correct Answer: (a) 1257
Solution:

Novels published by P = 384
Novels published by Q = 99
Novels published by R = 288
Novels published by S = 234
Novels published by T = 252
Total novels published = 384 + 99 + 288 + 234 + 252 = 1257

76. Calculate the ratio of differences between total books published by R and total books published by P and difference between total books published by T and total books published by Q?

Correct Answer: (b) 3 : 11
Solution:

Total books published by R = 624
Total books published by P = 552

Difference = 624 - 552 = 72
Total books published by T = 528
Total books published by Q = 264
Difference = 264
Required ratio = 72/264 = 3/11 = 3:11

77. Directions (77-81): Study the following information carefully and answer the related questions.

Following line-graph represents the data regarding male and female graduates in four different towns and table represents the ratio of employed to unemployed graduates in respective towns.

Ques: Total number of unemployed graduates in town A and C taken together are approximately what percent more/less than the total number of graduates in town A?

Correct Answer: (b) 25%
Solution:

Town

Number of graduates

Male

Female

Total

Employed

A

310

330

310 + 330 = 640

640 × 5/8 = 400

B

320

140

320 + 140 = 460

460 × 3/10 = 138

C

300

380

300 + 380 = 680

680 × 11/17 = 440

D

170

350

170 + 350 = 520

520 × 7/13 = 280

Total number of unemployed graduates in town A and C taken together = 240 + 240 = 480
Total number of graduates in town A = 640
Difference = 640 - 480 = 160
Therefore, percentage = (160/640) × 100 = 25%

78. What is the respective ration of total number of female graduates in town B and C together to the total number of male graduates from town A and D together?

Correct Answer: (a) 13:12
Solution:Total number of female graduates in town B and C together = 140 + 380 = 520
Total number of male graduates from town A and D together = 310 + 170 = 480
Therefore, ratio = 520 : 480 = 13 : 12

79. What is the average of total number of unemployed graduates in all given town taken together?

Correct Answer: (c) 260.5
Solution:

Average of total number of unemployed graduates in all given town taken together
= (240 + 322 + 240 + 240) / 4 = 260.5

80. If male to female employed graduates in town A and D taken together are in the ratio 1 : 3 respectively, then how many females employed graduates are there in town A and D taken together?

Correct Answer: (d) 510
Solution:

Number of employed graduates in town A and D taken together = 400 + 280 = 680
Therefore, total number of females employed graduates in town A and D taken together
= 680 × 3/4 = 510
