Question

sonam and shiny can complete a piece of work in 16 days.if sonam alone can do it in 48 days,how long will shiny take to finish the whole work?

Answer 1

Sonam and Shiny together can finish a piece in 16 days.

Sonam alone can do it in 48 days.
In 1 day she can do 1/48 of the work.
1/48 + 1/X = 1/16 or 3/48
1/X = 2/48
1/X = 1/24
therefore X = 24
Shiny can finish the work in 24 days.
