40% of a number when added to the square of the same number then it is...



Given:
- Let the number be x

Calculation:
1. 40% of the number:
- 40% of x = 0.4 * x = 0.4x
2. Square of the number:
- Square of x = x^2
3. When 40% of the number is added to the square of the number:
- 0.4x + x^2
4. Increased to 4040% of itself:
- 0.4x + x^2 = 4040% of x = 40.4x
5. Equation:
- 0.4x + x^2 = 40.4x
6. Solve for x:
- x^2 - 40x + 0.4x = 0
- x^2 - 39.6x = 0
- x(x - 39.6) = 0
- x = 0 (rejected) or x = 39.6
7. Actual number:
- The actual number is 39.6
