To complete the task Sandhya take x hours. After Two hours, she was called away. What fractional part of the assignment was left incomplete?
To complete the task sandhya take x hours. Therefore his speed in typing = 1/x. She was called away after 2 hours of typing. Therefore the work completed = (1/x) * 2. Therefore the remaining work to be completed = 1 – 2/x. (i.e.) work to be completed = (x-2)/x
