(D) 250 
(E) 315

NandishSS · Answer

45 percent of n is 405 =  \frac{45}{100}*n=405

n= \frac{(405*100)}{45}

35 percent of n ==> \frac{35}{100}*\frac{(405*100)}{45}  ==> \frac{35*405}{45}  ==>  315

Hence E

Kinshook · Answer

45% of n = 405 
=> n = 405/40%

35% of n =35% of 405/45% = 35%/45% * 405 = 7/9*405 = 315

E is correct answer.
