Directions: Read the table carefully and answer the following questions.
The table shows the total number of newspaper readers and the percentage distribution of readers reading TH, and TOI in 4 offices. All readers read only 3 newspapers i.e. TH, TOI, and IE.
| Offices | Total readers | TH (percent) | TOI (percent) |
|---|---|---|---|
| P | 400 | 30 | 40 |
| Q | 300 | 50 | 20 |
| R | 200 | 25 | 45 |
| S | 200 | 40 | 15 |
What is the difference between the maximum and the minimum number of readers of TH in any office?
120
150
100
80
90
Correct answer
100
Why this answer is correct
Number of readers of TH in P = 40/100 × 300 = 120
Number of readers of TH in Q = 50/100 × 300 = 150
Number of readers of TH in R = 25/100 × 200 = 50
Number of readers of TH in S = 40/100 × 200 = 80
Maximum number of readers of TH is in Q = 150
Minimum number of readers of TH is in R = 50
∴ Required difference = 150 – 50 = 100

| R | 200 | 25 | 45 |
| S | 200 | 40 | 15 |
What is the ratio of the readers of TH and TOI in P and R together to the TH and IE readers in Q and S together?
10 : 7
22 : 21
15 : 7
42 : 41
12 : 5
Correct answer
42 : 41
Why this answer is correct
Number of readers of TH and TOI in P and R = 70/100 × 400 + 70/100 × 200 = 420
Number of TH and IE readers in Q and S = 80/100 × 300 + 85/100 × 200 = 410
∴ Required ratio = 420 : 410 = 42 : 41

The number of TOI readers in all offices is what percent of IE readers in Q and R?
226.67%
166.67%
200%
83.33%
192.5%
Correct answer
226.67%
Why this answer is correct
Number of TOI readers in all offices = 40/100 × 400 + 20/100 × 300 + 45/100 × 200 + 15/100 × 200 = 340
Number of IE readers in Q and R = (100 – 50 – 20)/100 × 300 + (100 – 25 – 45)/100 × 200 = 150
∴ Required percent = 340/150 × 100 = 226.67%

10%
16.66%
5%
0%
20%
Correct answer
0%
Why this answer is correct
Number of IE readers in P = (100 – 30 – 40)/100 × 400 = 120
Number of readers of TOI in R and S = 45/100 × 200 + 15/100 × 200 = 120
∴ Required percent = (120 – 120)/120 × 100 = 0%

90
120
80
100
150
Correct answer
100

Total readers of TH in all offices = 30/100 × 400 + 50/100 × 300 + 25/100 × 200 + 40/100 × 200
= 400
∴ Required average = 400/4 = 100
