Assuming this post is from the same student who posted the other similar problem....

$1200 all invested at 6% would earn $72 interest; all at 8% would earn $96 interest; the actual interest was $90.

$90 is 18/24 = 3/4 of the way from $72 to $96, so 3/4 of the total was invested at the higher rate.

ANSWERS: 3/4 of $1200, or $900, was invested at 8%; the other $300 at 6%.

CHECK: .08(900)+.06(300) = 72+18 = 90
