Sorry for the late reply. You are correct the OA is A. I was checkin to see what other people thought here because I thought "unique" license plates meant that none of the letters or numbers could repeat. If that was the case then 36^6 wouldn't be the correct answer, but neither would anything else...

1)f(x)=x^2
f(a+b)=(a+b)^2
f(a)=a^2
f((b)=b^2
hence (a+b)^2#a^2+b^2

likewise solve u will get E as the ans for which LHS ans RHS are equally...
its all mental calculation....
E)
f(a+b)=-3(a+b)
fa=-3a
fb=-3b
fa+fb=-3(a+b)

x=sum of interior opp angles

using this formula we can get the other angle as 30 and hence the req side as same as 6


from 1st x can be either 2 or 3 not suff as we need only one value
from 2nd x can be either 3 or 4 same

from bth we come to knw that only one sol that is x=3 is possible

hence bth
