AfterR+2W = 2R,This gives R = 2W. So, total R would be 4W=4W+W+4+W/2 = 3W+2W

Note, there is no change in the number of blue chips, so
W+4 = 3W+2
W = 1
Which gives,
B = W+4 = 5
R = 2W = 2

R/T = 2/(1+5+2) = 1/4

If according to you B is 5 then why isn't your T equal to 10, as it is mentioned in the question "half the total number of chips would be blue chips"

B, R, W

B = R+4
2W+R = 2R i.e.
B = (1/2)*(R+W+B+2W)


i.e. R = 2W
and B = (1/2)*(5W+B)
i.e. B = 5W

i.e. B+R+W = (5W) + 2W + W = 8W

R/Total = (2W)/(8W) =0.25 1/4

Answer: Option D

The "after" is hypothetical situation. The present total is what I have mentioned and question asks for what the current situation is.

AfterR+2W = 2R,This gives R = 2W. So, total R would be 4W=4W+W+4+W/2 = 3W+2W

Note, there is no change in the number of blue chips, so
W+4 = 3W+2
W = 1
Which gives,
B = W+4 = 5
R = 2W = 2

R/T = 2/(1+5+2) = 1/4
