1Ans B
Substitute x=1001
and x=2,
U will get 2 eqns solving u will get 2000
Q If f is a real valued f(x) then
f(x) + 2f(2002/x)=3x
for all x>0 .Then f(2)
(A)1000
(B)2000
(C)3000
(D)4000

21F2 + 2F1001 = 3*2
F1001 + 2F2 = 3*1001

1If x = 2;
f(2) + 2 f(1001) = 6..................(1)
If x = 1001 ;
f(1001) + 2 f(2) = 3003...............(2)
(2) x 2 - (1)
f(2) = 2000 ....option (b)
