Laboratory B

Five years ago at Laboratory B, the ratio of doctorate to nondoctorate researchers was 2:3. If no researchers have resigned, what is the current ratio?

(1) In the last 5 years, twice as many doctorates were hired as nondoctorates.

(2) 50 doctorates were hired during the last 5 years.
