Answer 2

Answer:

⇒ Karan and Smith can complete total work in  $\frac{238}{31}$ days    

Step-by-step explanation:

Given data

Karan can finish a task in 14 days

let x be the task

⇒ the work done by Karan in 1 day = $\frac{x}{14}$  

Smith can finish a task in 17 days

⇒ the work done by Smith in 1 day = $\frac{x}{17}$  

⇒ here we need find how much time will they take to complete the same job together

from given data

the work done by Karan and Smith together in 1 day = $\frac{x}{14}+ \frac{x}{17}$

                                                                                 = $\frac{17x+ 14x }{238}$ =  $\frac{31x}{238}$  

$\frac{31x}{238}$  work can be done in 1 day

the total work x can be done in  = $x[\frac{238}{31x }]$ = $\frac{238}{31}$ days

⇒ Karan and Smith can complete total work in  $\frac{238}{31}$ days
