The number m was increased by 20%. The resulting number was again increased by 20%. As a result, the number 144 was obtained. Find m.
To complete this task, you need to create an equation. The first step is to increase the number m by 20%.
m + 0.2m = 1.2m.
We will increase the result obtained by another 20%.
1.2m + 0.2 * 1.2m = 1.2m + 0.24m = 1.44m.
Knowing that the obtained result is equal to 144, we draw up an equation and find the value of the original number.
1.44 * m = 144
M = 144 / 1.44 = 100.
Answer: 100.
