If average weight of all male stars 71.2kg and average weight of all female co-stars is 50.8kg. Mean weight of male and female stars is 60Kg, find ratio of male stars to female stars

23:28.

Step-by-step explanation:

Let m = number of male stars and f = the number of female stars.

Total weight  of all the stars = 71.2m + 50.8f.

As  the mean weight of all the stars = 60 we have

(71.2m + 50.8f) / ( m + f) = 60

71.2m + 50.8f = 60m + 60 f

11.2m = 9.2f

11.2m // f = 9.2

m / f = 9.2 / 11.2

m / f = 23/28.

The required ratio is 23:28.
