141. Directions [141-145]: Two persons A and B both read the same novel and end the novel in 5 days. The following bar graph shows the number of pages read by them per day.

(Bar graph showing Day 1 to Day 5 for A and B)

Ques. The average number of pages read by A in all five days together is:

Correct Answer: (c) 70
Solution:

Total number of pages in novel = 60 + 100 + 80 + 50 + 60 = 350
Required average = 350/5 = 70

142. Find the difference between the number of pages read by A on day1, day3 and day5 together and that of read by B on day2, day4, and day5 together.

Correct Answer: (a) 5
Solution:

Number of pages read by A on day1, day3 and day5 together = 60 + 80 + 60 = 200
Number of pages read by B on day2, day4 and day5 together = 85 + 60 + 60 = 205
Required difference = 205 - 200 = 5

143. The ratio between the total number of pages read by A and B together on day1 and that of on day3 is

Correct Answer: (c) 9:10
Solution:

Total number of pages read by A and B together on day1 = 60 + 75 = 135
Total number of pages read by A and B together on day3 = 80 + 70 = 150
Required ratio = 135 : 150 = 9 : 10

144. The number of pages read by A on day4 is what percent less than the number of pages read by B on day4?

Correct Answer: (e) None of these
Solution:Number of pages read by A on day4 = 50
Number of pages read by B on day4 = 60
Required percent = (60 - 50) × 100/60 = 100/6 = (50/3)%

145. Another person C read the same novel in 5 days also but he read same number of pages on each day. For what number of days the number of pages read by C is more than the number of pages read by A?

Correct Answer: (b) 3
Solution:

Number of pages read by C on each day = 350/5 = 70
So, on day1, day4 and day5 C read more number of pages than A.
So the number of days are 3.

146. Directions [146-150]: Read the data carefully and answer the following questions.

The table given below shows the data regarding number of people (male + female) who attended six different art exhibitions held in Delhi. The table also shows the percentage of males who attended the exhibition out of the total number of people who attended that exhibition.

Exhibition | Total number of people | Percentage of males

A             480                                25%
B             600                                65%
C             400                                45%
D             525                                60%
E              700                                55%
F              625                                40%

Note: No people attended more than one exhibition.

Ques : Find the average number of males who attended exhibitions A, C and D together.

Correct Answer: (b) 205
Solution:

For exhibition A:
Total number of people who attended the exhibition = 480
Percentage of males who attended the exhibition = 25%
Number of males who attended the exhibition = 25% of 480 = 480 × (1/4) = 120
Hence, number of females who attended the exhibition = 480 - 120 = 360

Similarly, we calculate the values for the remaining exhibitions and tabulate them.

F

375

Total number of males who attended exhibitions A, C and D together = 120 + 180 + 315 = 615
Hence, required average = 615/3 = 205

147. In which exhibition, the number of females who attended the exhibition is second highest?

Correct Answer: (a) A
Solution:The number of females who attended the exhibition A is 360 which is only less than the number of females who attended the exhibition F (375)

148. What is the respective ratio between total number of males who attended exhibitions D and E together to the total number of females who attended exhibitions B and D together?

Correct Answer: (d) 5:3
Solution:

Total number of males who attended exhibitions D and E together = 315 + 385 = 700
Total number of females who attended exhibitions B and D together = 210 + 210 = 420
Hence, required ratio = 700 : 420 = 5 : 3

149. The total number of people who attended exhibition D is what percent more/less than the total number of people who attended exhibition F?

Correct Answer: (c) 16%
Solution:Required % = [(625 - 525)/625] × 100 = 16%

150. If the number of females who attended exhibition E is ‘P’ percent of the total number of people who attended exhibition B, then find the value of ‘P’.

Correct Answer: (b) 52.5
Solution:

Number of females who attended exhibition E = 315
Total number of people who attended exhibition B = 600
Hence, required value of P = 315/600 × 100 = 52.5
