Let the stock value was x.

x* 0.85 * 1.07= 440

x= 440/0.85*1.07= 490 (approximately)

A is the answer

i m getting 483 as answer...
no choice seems to be the same...
can anyone confirm please

-15+7-(15*7)/100=-9.05% net decrease
let initial price be X
X(1-9.05/100)=440
X=44000/90.95 = ~483
:roll:

Ans A seems closer
Bunuel please confirm

thanks

Yes I agree. The answer should be of the form 48--. I guess if the question is correct, we will just have to go with the closest option.....

Okay....Since this involves calculation to a good extent ... any tips in general on fast calculations OR approximations?
May be taking this one as example how did you manipulate numbers to arrive at the final answer. {In shortest possible time}
