Answer 1

Kushal and nainsuk while working together can complete a piece of work in 64 hours while nikhil alone can do it in 96 hours how long will khusal take.

Answer 2

Answer:

192 hours

Step-by-step explanation:

Kushal and Nikhil can do a part of work in 64 hours = 1

So, Kushal and Nikhil can do a part of work in 1 hour = $\frac{1}{64}$

Nikhil can do a part of work in 96 hours = 1

Nikhil can do a part of work in 1 hour = $\frac{1}{96}$

So, Kushal can do a part of work in 1 hour = $\frac{1}{64}-\frac{1}{96}$

                                                                     = $\frac{1}{192}$

Kushal can do complete work in 192 hours .

Hence Kushal can do complete work alone in 192 hours .
