Problem Statement

We are given that: - The first typist takes 3 hours less time than the second typist to type a manuscript - Working together, they take 6 hours and 40 minutes to type the manuscript

Solution

Let's call the time taken by the first typist be x hours Then the time taken by the second typist is x + 3 hours Using the information given: x + (x + 3) = 6.67 hours (given time for both together) 2x + 3 = 6.67 2x = 3.67 x = 1.835 hours

Time taken by first typist (x) = 1.835 hours Time taken by second typist (x + 3) = 1.835 + 3 = 4.835 hours

So the time required by each typist individually is: - First typist: 1.835 hours - Second typist: 4.835 hours
