Given:
There are given that the final number is 150.
Step-by-step explanation:
According to the question:
We need to find the percentage number.
Then,
Suppose the percentage number is x.
Then,
The equation will be:

Now,
We need to solve the above equation for the value of x.
Then,
Divide by 150 on both sides of the equation:
![(150)/(150)* x\operatorname{\%}=(60)/(150)]()
Then,
![\begin{gathered} x\%=(60)/(150) \\ x\operatorname{\%}=(6)/(15) \\ x\operatorname{\%}=0.4 \\ x=0.4*100 \\ x=40 \end{gathered}]()
Final answer:
Hence, the percentage is 40%.
