Answer:

55 days

Step-by-step explanation:

Answer 2

Naveen will complete the remaining work in one day.

Given:

Ravi Manish and naveen alone can complete the work in 30days,15days and 10days respectively.

They started the work together but ravi leaves the work after 2 days of the starting and Manish leaves the work after 3days more.

To find:

How many days naveen will complete the remaining work.

Explanation:

Ravi do work in one day = $\frac{1}{30}$

Manish do work in one day = $\frac{1}{15}$

Naveen do work in one day = $\frac{1}{10}$

So total Ravi Manish and naveen will do work in one day =  $\frac{1}{30}$ + $\frac{1}{15}$ +  $\frac{1}{10}$

They started the work together but ravi leaves the work after 2 days

That is all three are working 2 days.

So Total two days work =  $\frac{2}{30}$ + $\frac{2}{15}$ +  $\frac{2}{10}$ = $\frac{24}{60}$  work complied in two days.

After that Ravi left work and three day work manish and naveen

So three day work of manish and naveen = $\frac{3}{15}$ +  $\frac{3}{10}$ = $\frac{30}{60}$

So total work done till now = $\frac{24}{60}$ + $\frac{30}{60}$ = $\frac{54}{60}$

Remaining work = 1- $\frac{54}{60}$ = $\frac{6}{60}$ = $\frac{1}{10}$

This work can complete naveen only

Its one day naveen work.

So naveen can complete work in 1 day.
