() If there are 18 engineers, find the number of doctors.
(ii) If there are 65 doctors, find the number of engineers​

Answer 1

Step-by-step explanation:

e:d = 2:5

i) e = 2parts = 18 => 1part =9

d = 5parts = 5×9 =45

no. of doctors =45

ii) d= 5parts = 65

1 part = 13

e = 2parts = 13×2 =26

no. of engineers = 26
