A month ago the ratia of nurses to doctors on a hospital staff was 3:5. Since that time two additional nurses joined the staff, no nurses left and the number of doctors remained the same. The ratio of nurses to doctors on the hospital staff is 4:5. How many nurses are now on the staff?

initially,let number of nurses and doctors be 3x and 5x.
now,number is 4x and 5x.
we know 2 new nurses joined,so,
4x-3x=2
x=2
so,now there are 4*2=8 nurses.

If adding two nurses increases the nurse ratio by 1 and the ratio is now 4:5,
2 x 4 = 8 nurses.
I'm afraid it's one of those ones you need to think about. I could be wrong though....
