Akuna Capital 25 Horses 2027: Classic Brain Teaser Solved

The Akuna Capital 25 horses brain teaser solution: 7 races. Race all five groups, race the five winners, then run one final race among the selected contenders to determine second and third. Commonly reported by candidates, this tests elimination logic — the answer is 7, not 6.

What This Question Assesses

This tests structured elimination reasoning. The interviewer wants the full logic: why 5 initial races, why the winners' race, and — the hard part — which horses can still contend for second and third and why the rest are eliminated. Most candidates get the first two steps and fumble the final selection.

How to Answer: Akuna Capital 25 Horses Brain Teaser

  • Step 1 — Five heats: race the 25 horses in five groups of five; label winners A1–E1 by finishing order of their groups.
  • Step 2 — Winners' race: race the five heat winners; suppose the order is A1 > B1 > C1 > D1 > E1. A1 is the fastest overall.
  • Step 3 — Eliminate: D1 and E1's groups cannot contain 2nd/3rd (three horses already beat their best); keep A2, A3, B1, B2, C1 as contenders.
  • Step 4 — Final race: race those five; the top two finishers are 2nd and 3rd fastest overall. Total: 5 + 1 + 1 = 7 races.

Example: "Five heats, then a winners' race — the winner is fastest overall. For second and third, only A2, A3, B1, B2, and C1 can still contend; one final race among them settles it. Seven races total."

Common Mistakes on Akuna Capital 25 Horses Brain Teaser

  • Answering 6 — forgetting that the final race needs five contenders (A2, A3, B1, B2, C1), not fewer.
  • Failing to justify eliminations — the logic of why D1's group is out is the scored reasoning.
  • Assuming no timing data — the puzzle gives only relative order per race; never assume cross-race times.

This teaser is famous because the final step is subtle. Learn the elimination logic properly once — interviewers always probe the last race.

FAQ

Why can't it be done in 6?

Because five horses can still contend for 2nd/3rd and only five run per race — the final race is unavoidable.

What if I only need the fastest?

Six races: five heats plus the winners' race. The seventh race is only for 2nd and 3rd.

Do I need to consider ties?

Assume no ties unless stated — and mention the assumption, which shows rigor.

What is the general lesson?

Elimination logic: each race's information prunes the contender set. State what each race proves.
