This one's tricky because the two-stage setup feels more complicated than it actually is. Let me work through it.
Setup: Three departments get interns in two stages. Stage 1: each department gets the same number (call it n). Stage 2: remaining interns go proportionally to what each department originally requested.
The question asks: did Marketing request more than half of all interns?
Statement (1): One-fourth of all interns were assigned in Stage 1.
So Stage 1 = (1/4)Total, which means 3n = (1/4)Total. That tells us how big Stage 1 is relative to the whole, but nothing about what Marketing requested. You could have Marketing requesting 60% or 40% of the Stage 2 pool and this statement says nothing about it. NOT SUFFICIENT.
Statement (2): Total assigned to Marketing was 25% more than the combined total of Accounting and Production.
So Marketing = 1.25 x (Accounting + Production). Since all three sum to the total, this gives us Marketing = 1.25 x (Total - Marketing), which means 2.25 x Marketing = 1.25 x Total, so Marketing = (1.25/2.25) x Total = 5/9 of Total.
Now here's the key move: Marketing ended up with 5/9 of all interns, which is more than half the total. In Stage 1, Marketing got exactly n, which is 1/3 of Stage 1. Since Marketing got a below-average share in Stage 1, it must have gotten an above-average share of Stage 2 to end up above 50% overall. Stage 2 is distributed proportionally to original requests, so Marketing's Stage 2 share > 50% means Marketing requested > 50% of the total. YES to the question. SUFFICIENT.
Answer: B.
The trap most people fall into here is thinking Statement (2) only tells you about the final assignment totals, not the original requests. But the proportional distribution mechanic in Stage 2 connects those two things directly.
