let no. male players be x and female players be y
as per the question stem : x*95/100+y*115/100 = (x+y)*110/100 => y/x =3/1 -> option E

Even the increase no. would drift with the same ratio cause we are considering an overall increase in the same exact proportion. We can't ascertain a ratio with the conditional part of a question stem and it was mentioned only to manipulate it further. Assume total to be 100; let x and y part be 30 and 70. Now, an overall increase of 10% will also let x and y part to go up by 3 and 7 respectively and not to mention that the ratio doesn't change.

Veritas Prep Official Solution:

We can solve this one with the weighted average mapping strategy or with algebra. For the mapping strategy:

-5%...............10%......15%

M..........15...........5......F

This gives us a female:male ratio of 15:5, or 3:1.

To solve algebraically, we can set up the following equation:
$$1.1(f+m)=1.15f+.95m$$. By manipulating, we can get to $$0.15m =0.05f$$, or $$\frac{f}{m}=\frac{0.15}{0.05}=\frac{3}{1}$$.
