working together tom and ricky can complete a piece of work in 6 days and working alone tom can complete same work in 10 days. how much time ricky takes

Answer 1

Ricky can do the work in 15days

Answer 2

Answer:

Ricky takes 15 days to complete work

Step-by-step explanation:

They can complete work together in days = 6

They can do a part of work in 1 day = $\frac{1}{6}$

Alone tom can complete same work in 10 days.

Tom  can do a part of work in 1 day = $\frac{1}{10}$

Ricky can do a part of work in 1 day = $\frac{1}{6}-\frac{1}{10}$

                                                           = $\frac{1}{15}$

Ricky can do $\frac{1}{15}$ part of work in day = 1

So, Ricky can do complete work in day = 15

Hence Ricky takes 15 days to complete work
