Free Figure Series IQ Test: Can You Spot the Pattern?

This puzzle is a standard part of a Professional IQ Intelligence Test, specifically measuring your Mathematical Logic and Deductive Reasoning skills. Solving these geometric equations is a powerful form of Brain Fitness that supports Cognitive Health and Healthy Aging. We can solve this step-by-step using a simple "substitution method": First Scale: We established a base value where "One Orange Diamond + One Purple Rectangle = 8." Second Scale: The equation expands to "One Purple Rectangle + One Green Octagon + One Orange Diamond = 15." Find the Octagon Value (The Key Step): From the first scale, we already know the "Diamond + Rectangle" pair equals 8. By replacing that pair in the second scale, the equation becomes "8 + Green Octagon = 15." Using basic subtraction: 15 - 8 = 7. Therefore, one Green Octagon = 7. Calculate the Final Answer: The third scale asks for the total value of "Two" Green Octagons. Calculation: 7 + 7 = 14. Conclusion: The correct value for the question mark is 14, matching Option C. Stay Sharp Tip: Think of this as a shopping scenario where you are figuring out the price of individual items based on group totals.
