The heavy-weight showdown: what is the weight of the white ball?

Hey there, vinyl junkies, pub-quiz regulars, and classic rock veterans! Ready to pause your favorite playlist and test your physics radar on this high-stakes balance scale?

Take a look at this two-tiered scale puzzle. You’ve got pink balls, white balls, and a labeled weight of 90 hanging on a mobile-style setup. At first glance, it looks like a breeze. You glance at the 90, do some quick math in your head, and drop a guess.

But hold your spatulas! Most people fall headfirst into the hanging-scale trap and guess 30 or 45! Can you dodge the physical illusion and calculate the exact weight of one white ball?

The Scene & The Setup

Let’s break down the scales before we drop the needle on the solution:

=

The Small Scale (Right Side): 3 Pink Balls on the left pan balance perfectly with a 90 weight on the right pan.

The Main Scale (Top Level): 2 White Balls + 1 Pink Ball on the left pan balance perfectly with the ENTIRE small scale hanging off the right hook.

YOUR MISSION (IF YOU CHOOSE TO ACCEPT IT):

Channel your inner hawk-eyed tour manager and run through the step-by-step soundcheck:

Step 1: Crack the Pink Ball

The small scale is level, meaning 3 Pink Balls equal 90.

Pink Ball = 90 ÷  3 = 30

Step 2: Avoid the Hanging Scale Trap!

Here’s where 90% of people slip up! The main scale isn’t holding just the 90 weight—it’s holding the entire hanging assembly!

Left pan of small scale = 3 Pink Balls = 90

Right pan of small scale = Labeled weight = 90

Total weight on the right hook = 90 + 90 = 180

Step 3: Solve for the White Ball

The top main scale is balanced, so:
