Number of books sold by division C

= 130000 ×  50.4  ×  11  = 14300

360 12

Number of books unsold by division D
= 130000 ×  28.8  ×  3  = 3900
360 8

∴ Required ratio = 15925 : (11375 + 3900) = 15925 : 15275 = 637 : 611 = 49 : 47

Hence, option D is correct.

Granthbhavan’s total count of published books fell by 9% in the next set of three months. If one-fourth of these books were published by division E, how many books did the other divisions publish?
» Explain it
A
Number of books published by Granthbhavan in the next set of three months = 91% of 130000 = 118300
 
Since division E published one-fourth of these (i.e. 25%), the remaining divisions published 75% of the total books published. 
 
∴ Number of books published by the remaining divisions = 0.75 × 118300 = 88725
 
Hence, option A is correct.
