doctors and lawyers is 40. If the average age of the doctors is 35

and the average age of the lawyers is 50, then what is the ratio of

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
