Thread: rati word poblem

an absent minded doctor cannot remember how many patients are on his registar. records show that the ratio of male to females patients is 2:3 and the ratio of private to NHS patients is 2:5 . How many patients are on the registar,


chose from
a)60
b)63
c)70

the total number of patients must be divisible by 5 and by 7 ...

so its 70?

yes, both ratio's have to be divisible by the same number

do you understand how I came up with 5 and 7?
