Only 20% of Adults Can Solve This IQ Test: Are You Among Them?

Donna’s Pizza Challenge has become a viral IQ test that only 20% of adults solve correctly. The puzzle seems simple: Donna eats 1/4 of a pizza in 1 minute. How long will it take her to eat 2.5 pizzas?

Step-by-Step Solution:

  1. Donna’s Eating Speed: She eats 1/4 of a pizza in 1 minute. To eat one whole pizza, she needs 4 minutes (1/4 × 4 = 1 pizza).
  2. Scaling Up: Now, to eat 2.5 pizzas, we multiply the time for 1 pizza (4 minutes) by 2.5:
    4 minutes × 2.5 pizzas = 10 minutes.

Why It’s Tricky:

  • Many rush and mistakenly think Donna eats a whole pizza in 1 minute or confuse the fractions, leading to wrong answers.
  • The key is understanding fractions and scaling—often overlooked in daily life.

Why It Matters:

This puzzle is more than just an IQ test. It’s about clear thinking, breaking problems into manageable steps, and avoiding overcomplication. The ability to apply basic math and logical reasoning in everyday situations—like managing time, scaling recipes, or even budgeting—is crucial.

Bonus Tip: Next time you face a tricky problem, remember Donna’s pizza. Break it down, stay calm, and approach it step by step. It’s a skill that will pay off in both simple and complex challenges!
