1. We are given that 40 subtracted from 60% of a number results in 50. 2. Let the number be $x$. 3. 60% of $x$ can be written as $0.6x$. 4. The equation based on the problem statement is $0.6x - 40 = 50$. 5. Add 40 to both sides: $0.6x = 50 + 40$. 6. Simplify the right side: $0.6x = 90$. 7. Divide both sides by 0.6 to solve for $x$: $x = \frac{90}{0.6}$. 8. Calculate the division: $x = 150$. Final answer: The number is $150$.
