Dolar's 1 hour's work = $\frac{1}{4}$

(Zoha & Khadem)'s 1 hour's work = $\frac{1}{3}$

(Dolar & Khadem)'s 1 hour's work = $\frac{1}{2}$

(Dolar, Zoha & Khadem)'s 1 hour's work $= \frac{1}{4} + \frac{1}{3} = \frac{7}{12}$

Zoha's 1 hour's work = $\frac{7}{12} - \frac{1}{2}$ = $\frac{1}{12}$

Time taken by Zoha to complete the work 12 hours
