Answer 2

Answer:

9.6 days.

Step-by-step explanation:

Since, the time taken by Arvind to cultivate the piece of land = 16 days,

⇒ His one day work = 1/16,

And, the time taken by Bimal to cultivate the piece of land = 12 days,

⇒ His one day work = 1/12,

Also, the time taken by Arvind, Bimal and Chetan to cultivate the piece of land = 4 days,

⇒There one day work = 1/4,

Since, Chetan's one day work = One day work of Arvind, Bimal and Chetan - ( Arvind's one day work + Bimal's one day work )

=  $\frac{1}{4}-(\frac{1}{16}+\frac{1}{12})$

= $\frac{1}{4}-\frac{3+4}{48}$

= $\frac{1}{4}-\frac{7}{48}=\frac{12-7}{48}=\frac{5}{48}$

Hence, the time taken by Chetan when he works alone = 1 / His one day work

= 48/5

= 9.6 days.
