Which number when squared is increased by 500%?

Explanation

To solve this question, we need to find the number that, when squared, increases by 500% compared to its original value.First, understand that a 500% increase means the final value is 6 times the original (100% original + 500% increase = 600% total).Let's analyze the correct option:For 6: When squared, 6 becomes 36. The percentage increase is calculated as: (36 - 6) / 6 x 100 = 500%. This confirms that squaring 6 results in a 500% increase.Now, examine the incorrect options:Option 5: Squaring 5 gives 25, which increases by 400%.Option 7: Squaring 7 gives 49, which increases by 600%.Option 10: Squaring 10 gives 100, which increases by 900%.Thus, 6 is the only number that, when squared, increases by exactly 500%.
