If
50000=25000*p/(100-p)
50000(100-p)=25,000p
5,000,000-50,000p=25,000p add the 50,000
5,000,000=50,000p+25,000p
5,000,000=75,000p
p=5,000,000/75,000
p=66.66

The possible answers might be 3 (or) -25. There’s no -25 among answers so I suppose it’s B.
Step-by-step explanation:
best way to see it check the substitution and the numbering
24+24+15+15= the perimeter, aka 48+30 aka 78 meters
