The total number of newspapers sold by E is 960.
Total newspapers and magazines sold by E = 2400
Percentage of newspapers sold by E = a%
So:
Number of newspapers sold by E = a / 100 × 2400 = 960
a / 100 × 2400 = 960
24a = 960
a = 40
Organization A:
Total newspapers and magazines sold = 840
Percentage of newspapers sold = 36.66%
Number of newspapers sold = 36.66 / 100 × 840 = 308
Number of magazines sold = 840 - 308 = 532
Organization B:
Total newspapers and magazines sold = 1440
Percentage of newspapers sold = 42.22%
Number of newspapers sold = 42.22 / 100 × 1440 = 608
Number of magazines sold = 1440 - 608 = 832
Organization C:
Total newspapers and magazines sold = 2420
Percentage of newspapers sold = 45.45%
Number of newspapers sold = 45.45 / 100 × 2420 = 1100
Number of magazines sold = 2420 - 1100 = 1320
Organization D:
Total newspapers and magazines sold = 2880
Percentage of newspapers sold = 31.25%
Number of newspapers sold = 31.25 / 100 × 2880 = 900
Number of magazines sold = 2880 - 900 = 1980
Organization E:
Total newspapers and magazines sold = 2400
Percentage of newspapers sold = 40%
Number of newspapers sold = 960
Number of magazines sold = 2400 - 960 = 1440
| Organization | Total Newspapers and Magazines Sold | Newspapers Sold | Magazines Sold |
|---|---|---|---|
| A | 840 | 308 | 532 |
| B | 1440 | 608 | 832 |
| C | 2420 | 1100 | 1320 |
| D | 2880 | 900 | 1980 |
| E | 2400 | 960 | 1440 |
Calculations:
Number of magazines sold by A is x% of the total number of newspapers and magazines sold by A, so x% = 532 / 840 × 100 = 19/30
Number of newspapers sold by D is y% of the number of newspapers sold by C, so y% = 900 / 1100 × 100 = 9/11
Difference between x% of the number of magazines sold by D and y% of the number of newspapers sold by C:
= 19 / 30 × 1980 - 9 / 11 × 1100 = 354
Thus, the correct answer is 354.
