Answer
It does not make sense.
Work Step by Step
Let \[x\] be the original price of computer.
Reduced computer price is \[\$780\].
It means,
\[\begin{align}
& x-0.35x=780 \\
& 0.65x=780 \\
& x=\frac{780}{0.65} \\
& x=1,200
\end{align}\]
The original price of computer is \[\$1,200\].
So, \[x-0.35x=780\] is the correct equation of a problem which is not given in the problem.
Hence, the provided statement does not make sense.
