During an evaluation of a new diagnostic imaging modality for detecting salivary gland tumors, 90 patients tested positive, out of the 100 patients who tested positive with the gold standard test (with disease, true positives). A total of 80 individuals tested negative with the new test, out of the 100 individuals who tested negative with the gold standard test (without disease, true negatives). What is the positive likelihood ratio for this test?
1) 90/110
2) 80/90
3) 90/20
4) 10/80
5) 90/100
