I did the same, and the question did mention equal weight, that I missed during the first read.Thank you David! I used this formula and as people have mentioned my answer didn't match too. Then I tweaked the formula to factor in weights of the respective ULs
( ((1/2)^2 * 64^2) + ((1/2)^2 96^2) + (2*1/2*1/2*0.450*64*96)) = 68.63. If I remember correctly, there was a 69 in one of the options. Marked it and moved on only to panic and miss out on some easier ones towards the end :|
