Let the total marks are 100.

And Bradely got 66% marks.

So the marks of Bradely are:

[tex]\begin{gathered} M_B=\frac{66}{100}\times100 \\ M_B=66 \end{gathered}[/tex]

And Zevel got one third of Bradely's marks so:

[tex]\begin{gathered} M_Z=\frac{1}{3}M_B \\ M_Z=\frac{1}{3}\times66 \\ M_Z=22 \end{gathered}[/tex]
