D) 673
E) 676
Correct Answer: D
Solution :
| Number of books sold in the year 2012 |
| \[=945\times \frac{8}{15}=504\] |
| Number of books sold in the year 2013 |
| \[=1240\times \frac{3}{4}=310\times 3=930\] |
| Total number of fiction books sold in the years 2012 and 2013 \[=504+930=1434\] |
| Number of non-fiction books sold in the year 2011 \[=720\times \frac{4}{9}=320\] |
| Number of non-fiction books sold in the year 2012 |
| \[=945\times \frac{7}{15}=63\times 7=441\] |
| Total number of non-fiction books sold in the years |
| 2011 and 2012 together \[=320+441=761\] |
| \[\therefore \] Required difference \[=1434-761=673\] |
