Answer:
A stenographer will type 80 words.
Explanation:
In this question it is given that average typing speed of a stenographer is 100 words per minute and we have to calculate the words a stenographer will type in 4/5 of a minute.
By using unitary method we will calculate the number of words a stenographer will type.
∵ In 1 minute stenographer is typing words = 100
∴ in 4/5 minutes stenographer will type = 100 × (4/5) words
