0.04% will be the answer only if CPU is fetching and executing instructions at an average rate of one million instructions per second.

Assuming there is a misprint in the question, CPU is fetching and executing million instructions per second.

Device transmits 1600 characters per second, or 400 words per second.

Hence, %age of cycles stolen = $\large \frac{400}{10^6} \times 100 = 0.04$
