The average typing speed of a stenographer is 100 words per minute. how many words would a stenographer type in 4⁄5 of a minute if typing at the average speed

A stenographer will type 80 words.

Step-by-step 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

                                                                  = 400/5 = 80 words

So the answer is a stenographer will type 80 words in 4/5 of a minutes.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
