the number of doctors to the number of lawyers?

**Reiny**, Wednesday, April 2, 2008 at 10:00pmlet the number of doctors be d

let the number of lawyers be l

total of ages of doctors = 35d

total of ages of lawyers = 50l

total of both groups = 35d+50l

but this is also equal to 40(d+l)

so 40(d+l) = 35d + 50l

40d + 40l = 35d + 50l

5d = 10l

d/l = 10/2 = 2:1
