Visual math puzzles and scale equations are popular social media teasers that test basic algebra, observation, and mental arithmetic. In this puzzle, three kitchen scales display the combined weights of different cutlery items—spoons, forks, and a coffee cup.
By setting up simple equations from left to right, we can easily determine the individual weight of each item and solve for the weight of the cup. Below is the full step-by-step mathematical breakdown.
Step-by-Step Mathematical Solution
Here is how to calculate the exact weight of each item:
-
1. Find the weight of one spoon ($S$):
-
The first scale shows 3 identical spoons weighing a total of 90g.
-
$$3S = 90\text{ g} \implies S = \frac{90}{3} = 30\text{ g}$$
-
-
2. Find the weight of one fork ($F$):
-
The second scale shows 1 spoon and 1 fork weighing a total of 55g.
-
$$S + F = 55\text{ g}$$
-
Substitute $S = 30\text{ g}$:
-
$$30 + F = 55\text{ g} \implies F = 55 – 30 = 25\text{ g}$$
-
-
3. Calculate the weight of the cup ($C$):
-
The third scale shows 1 fork and 1 cup weighing a total of 175g.
-
$$F + C = 175\text{ g}$$
-
Substitute $F = 25\text{ g}$:
-
$$25 + C = 175\text{ g} \implies C = 175 – 25 = 150\text{ g}$$
-
Item Weight Summary
| Item | Equation | Weight |
| Spoon ($S$) | $90\text{ g} \div 3$ | 30 g |
| Fork ($F$) | $55\text{ g} – 30\text{ g}$ | 25 g |
| Cup ($C$) | $175\text{ g} – 25\text{ g}$ | 150 g |
