Take your time with this puzzle:

As you can see, the first three equations have exact solutions. Can you get the answer to the fourth one without having to scroll down?

## How to Find the Solution

- The first equation shows a summation in which the three lipsticks give a result equal to 30.
- The next equation sums up one lipstick and two mirrors giving a result of 20.
- Equation 3 represents a summation of two pairs of nail polish and one mirror to give a result of 9
- The final equation is the one with a question mark. It is a representation of one mirror, one nail polish, and a lipstick.

Did you get an answer?

## The Solution

To solve the fourth equation, you will need to use the first three so that you can determine what each component stands for.

- In the first equation, all three lipstick represent the same number. You find this number by dividing the result by 3 to get 10. Therefore, one lipstick represents the number 10.
- Taking 10 as your base value for the lipstick, you find that both mirrors represent 10 in equation number 2. Every mirror is then determined to be equal to a value of 5.
- Taking 5 and adding two pairs of nail polishes will give a value of 9. You can tell that every pair of lipstick represents a value of 2.
- This only leaves you with one lipstick representing a value of 1.
- The final equation can then be represented by 5 + 1 x 10

The equation simplifies to** **5 + 1 x 10, which gives a value of 15.

**The answer is, therefore, 15. **
