Given information:
- First number = 270
- First number is 75% of second number
- Second number is 125% of third number
To find:
- Third number
Solution:
1. Let's assume the third number to be x.
2. From the given information, we know:
- First number = 75% of second number
- Second number = 125% of third number
3. Using the above information, we can write the following equations:
- First number = 0.75 x Second number
- Second number = 1.25 x Third number
4. Substituting the values in the above equations, we get:
- 270 = 0.75 x Second number
- Second number = 270 / 0.75 = 360
- 360 = 1.25 x Third number
- Third number = 360 / 1.25 = 288
5. Therefore, the value of the third number is 288.
