E. 180.
x=old price
n = number of pendrives can be purchased at x price

before; xn=360
after; x(n+2) = 400
solving the above equations, x=20 and n=18
so, new price = 10 (1-0.1) x= 10 (0.9) 20 = 180

Original = x
New = 0.9x

360/x + 2 = 360/0.9x
x = 20

New price = 18
10 pen drives = 180 (E)

first time I got a correct answer in a question of this nature!
E.180
x'*q'=x*q
q'=q+2
x'=0.9x
solve and get q
then it's easy
