Total Questions: 250

231. Directions [231-235]: Read the data carefully and answer the following questions.

The table given below shows the total number of messages received by five different customer service agents in a week and the percentage of read messages out of the total messages received by these agents.

Customer service agent

Q

450

40%

R

360

55%

S

480

45%

T

320

70%

Note: Total messages received = Number of read messages + Number of unread messages.

Ques : The number of unread messages of customer service agent R is what percent more/less than the number of read messages of customer service agent S?

Correct Answer: (b) 25%
Solution:

For customer service agent P:
Total messages received = 240
Percentage of read messages = 60%
Hence, number of read messages = (3/5) × 240 = 144
And number of unread messages = (240 - 144) = 96
Similarly, we calculate the values for the remaining customer service agents and tabulate them.

 Number of unread messages of customer service agent R = 162

232. Find the ratio of the number of read messages of customer service agent T to the number of unread messages of customer service agent P.

Correct Answer: (c) 7:3
Solution:Number of read messages of customer service agent T = 224
Number of unread messages of customer service agent P = 96
Hence, required ratio = 224 : 96 = 7 : 3

233. If the difference between the number of unread messages of customer service agents Q and Z is 68, find the number of unread messages of customer service agent Z.

Correct Answer: (e) Both a and c
Solution:

Number of unread messages of customer service agent Q = 270
Difference between the number of unread messages of customer service agents Q and Z = 68
Let the number of unread messages of customer service agent Z be ‘t’

Case 1: t > 270
According to the question:
⇒ t - 270 = 68
⇒ t = 338

Case 2: t < 270
⇒ 270 - t = 68
⇒ t = 202

234. Find the average number of messages received by customer service agents P, R and S together.

Correct Answer: (a) 360
Solution:

Required average = (240 + 360 + 480)/3 = 360

235. If the total number of messages received by customer service agent V is 12.5% less than that of customer service agent R, find the total messages received by customer service agent V.

Correct Answer: (e) 315
Solution:Total number of messages received by customer service agent R = 360
Total messages received by customer service agent V = (7/8) × 360 = 315

236. Directions [236-240]: Study the data given below and answer the given questions:

Below pie chart shows the percentage distribution of notebooks manufactured by five companies in a month:

Total number of notebooks manufactured by five companies in a month = 48000

Ques: What is the ratio of number of notebooks manufactured by T and U together to the number of notebooks manufactured by W alone?

Correct Answer: (c) 10:13
Solution:

The number of Notebooks manufactured by both T and U together = (16 + 14)% of 48000
The number of Notebooks manufactured by both T and U together = (39)% of 48000
Required ratio = (16 + 14) × 48000 : (39) × 48000 = 10 : 13

237. If the number of notebooks manufactured by A and B are 20% and 25% more than the number of notebooks manufactured by U and V respectively, then what is the average number of notebooks manufactured by A and B together?

Correct Answer: (d) 7032
Solution:The number of notebooks manufactured by A = (120/100) × (14/100) × 48000 = 8064
The number of notebooks manufactured by B = (125/100) × (10/100) × 48000 = 6000
Required average = (8064 + 6000)/2 = 7032

238. The number of notebooks manufactured by V is what percentage more less than the number of notebooks manufactured by T?

Correct Answer: (b) 37.5%
Solution:

The number of Notebooks manufactured by T = 16% of 48000
The number of Notebooks manufactured by V = 10% of 48000
Required % = [(16 - 10) × 48000/(16 × 48000)] × 100
= (16 - 10)/16 × 100 = 37.5%

239. What is the average number of notebooks manufactured by U and W together?

Correct Answer: (a) 12720
Solution:

The number of Notebooks manufactured by U = 14% of 48000
The number of Notebooks manufactured by W = 39% of 48000
Required average = ((14 + 39)/200) × 48000
= 12720

240. The number of notebooks manufactured by S is what percentage of the number of notebooks manufactured by U?

Correct Answer: (c) 150%
Solution:The number of Notebooks manufactured by S = 21% of 48000
The number of Notebooks manufactured by U = 14% of 48000
Required % = (21/14) × 100 = 150%
