Number of female candidates in electronics = 30000
Number of female candidates in mechanical = 20000
Required difference = 10000

62. What is total number of male candidates appeared in the exam?

Correct Answer: (c) 363500
Solution:

Total Number of male candidates who appeared in the exam is 363500

63. Which of the following statements is correct?

Correct Answer: (c) The number of males who appeared in mechanical is 20% more than the number of males who appeared in electronics.
Solution:The number of males who appeared in mechanical = 90000
The number of males who appeared in electronics = 75000
Required % = (90000 - 75000)/75000 × 100 = 20%

64. In how many streams is the number of female candidates less than 25000?

Correct Answer: (b) 2
Solution:

In two streams, mechanical and civil, the number of female candidates is less than 25000.

65. If 56% of the female candidates cleared the exam, how many female candidates disqualified?

Correct Answer: (b) 60060
Solution:

Total number of female candidates = 136500
Number of disqualified female candidates = (1 - 0.56) × 136500 = 60060

66. Directions (66-70): The pie chart below shows the number of history books in 5 stores namely A, B, C, D and E. Also, table represents the percentage of polity books out of the total books in the store. Total books in the store contain only history and polity books.

Number of History books

Store

Percentage of Polity books

A

70%

B

40%

C

50%

D

30%

E

60%

Ques : Find the ratio between the history books in store D and polity books in store E respectively?

Correct Answer: (d) 7 : 9
Solution:

Number of History books in store A = 150 = 30% of total books

Number of Polity books in Store A = (150×70)/30 = 350

Similarly, the number of polity books for each store can be calculated

Number of Polity books in store B = (120×40)/60 = 80
Number of Polity books in store C = (140×50)/50 = 140
Number of polity books in store D = (210×30)/70 = 90
Number of Polity books in store E = (180×60)/40 = 270

History books in store D = 210
Polity books in store E = 270
Ratio = 210 : 270 = 7 : 9

67. The polity books in store C are approximately what percent of history books in store E? (a) 83.2%

Correct Answer: (b) 77.78%
Solution:Polity books in store C = 140
History books in store E = 180
Required percentage = (140×100)/180 = 700/9 = 77.78%

68. There is another store F, which has history books 20% more than the history books in store . Find the ratio between the history books in store B and store F respectively?

Correct Answer: (c) 2 : 3
Solution:History books in store A = 150
History books in store F = 120% of 150 = 180
History books in store B = 120
Ratio between the history books in store B and F = 120 : 180 = 2 : 3

69. If the 20% of the history books from store A and 30% of polity books from C are sold. Find the difference of the unsold history books from store A and sold polity books from store C?

Correct Answer: (a) 78
Solution:

History books
Store A = 150
Books sold = 20% of 150 = 30
Books unsold = 150 - 30 = 120

Polity books
Store C = 140
Books sold = 30% of 140 = 42

Required difference = 120 - 42 = 78

70. Find the total number of polity books from store B, C and D?

Correct Answer: (b) 310
Solution:

Polity books
Store B = 80
Store C = 140
Store D = 90

Total = 80 + 140 + 90 = 310
