```							let ratio of engineers and doctors be 2x:5xtherefore if there are 18 engineersthen 2x=18          x=18/2          x=9then number of doctors= 5x= 5(9)=45if there are 65 doctorsthen 5x=65          x=65/5          x=13then number of engineers=2x=2(13)=26

```							Since the ratio of engineers to doctors is 2:5 we can let the number of engineers to be 2x and number of doctors to be 5xIt is given that there are 18 engineers so according to the above assumption, 2x=18 and x=9No. of doctors = 5x= 5*9 =45The second part can be solved similarly as 5x=65 and x=13So number of engineers = 2x= 2*13=26
