Efficiency of genelia is 25% more than jessica and jessica takes 25 days to complete a piece of work. genelia started a work alone and then jessica joined her 5 days before actual completion of the work, for how many days genelia worked alone

Answer 1

Jessica works for 25 days to complete a piece of work.

Since Genelia is 25% efficient than Jessica, Genelia will take less days by 25% to complete the work.

75/100 × 25 = 18.75 days

Jessica joined 5 days before completion.

18.75 - 5 = 13.75 days

13.75 days that Genelia work alone.
