On January 1, 2026, Atlas Fitness had 48,000 more active members than Beacon Fitness. During 2026, the number of active members at each gym increased by p percent. After the increase, how many more active members did Atlas Fitness have than Beacon Fitness did?

(1) On January 1, 2026, Beacon Fitness’s number of active members was 5/11 of Atlas Fitness’s number of active members.

(2) p = 15

So AF had 48000 more members than BF, that is AF = BF + 48000.
After increase of p %, AF becomes \(AF(1+\frac{p}{100})\) and BF becomes \(BF(1+\frac{p}{100})\).
We have to find their difference.
\(AF(1+\frac{p}{100}) - BF(1+\frac{p}{100}) = (AF-BF)(1+\frac{p}{100}) = 48000(1+\frac{p}{100}).\)
To find the value of the expression, we just require value of p.

Statement 1 does not give the value of p, while statement 2 directly tells us that p is 15.
Thus Statement 2 is sufficient.

Answer B

If it were PS question, the answer would be 48000(1+15/100) = 48000×115/100 = 55200.
