Question

When a number is decreased by 40% of itself, the result is 54 . What is the number?

Answer 1

90

Explanation:

We can translate this into the following equation:

x - 0.4x = 54

Simplifying the left side of the equation, we get:

0.6x = 54

Dividing both sides by 0.6, we get the following:

x = 90

Therefore, 90 is the number decreased by 40% leaving 54.
