Answer 2

Total number of words typed in 4 minutes$=80$

Number of erroneous words$=12$

No. of words typed in a minute including erroneous word$=\frac{80}{4}=20$

Hence gross speed is 20 words per minute.

No. of correct words typed in a minute $=\frac{(80-12)}{4} =\frac{68}{4}=17$

Hence net speed is 17 words per minute.

Accuracy percentage

$= \frac{number \ of\ actual\ correct\ words\ typed}{Total\ number \ of \ actual \ words \ typed} \times 100\\\\=\frac{17}{20}\times 100\\ \\=85\%$

Hence the accuracy percentage is 85%.
