are ≥0.25e >55yo

1)f is a subset of e. and, of them means 2/5·40%=16%.
Must be a whole number of people. At a minimum this is 4 females from a total of 25 (as 0.16=16/100=4/25)
Don't know numbers concerning men. Insufficient

2) 20 men are over 55. Don't know total number of men. Don't know numbers concerning females.
Insufficient

Together
Assume all men are over 55

$$\frac{(20+4)}{(20+25)}$$=$$\frac{24}{45}$$ which is greater than half, so greater than 0.25

$$\frac{(20+4)}{(9999999+25)}$$ is well below 0.25

Insufficient
